Magical 2-Cup Summer Squash Cake Recipe Everyone Loves

Nothing says summer quite like baking with fresh garden produce, and my Summer Squash Cake is the ultimate way to celebrate the season! This unexpectedly moist cake has a delicate sweetness that’ll make you forget it’s packed with veggies. The magic? A mix of zucchini and yellow squash—trust me, it makes all the difference.

I first fell in love with this recipe at my aunt’s backyard barbecue years ago. One bite of her lightly spiced cake with that tangy cream cheese frosting, and I begged for the recipe. Now it’s my go-to for potlucks—no one ever guesses there’s squash in there until I tell them! The texture is incredible—somehow both dense and light, with just the right amount of crumb. Plus, it’s a fantastic way to use up that summer squash bounty when your garden (or farmer’s market haul) gets overwhelming.

Ingredients for Summer Squash Cake

Gathering the right ingredients makes all the difference with this cake. I’ve learned through trial and error that quality and prep matter—especially with the squash. Here’s everything you’ll need, organized so you can scan quickly while baking.

Cake Batter Ingredients

This batter comes together so easily, but the magic’s in the details. I always set my eggs out early—room temperature eggs blend better with the oil for that perfect crumb.

Wet Ingredients

• 3 large eggs (set out 30 minutes ahead—cold eggs make dense cakes)
• 2 cups grated summer squash (I do 1 cup zucchini + 1 cup yellow squash for color)
• 1 1/2 cups sugar (plain white sugar lets the squash flavor shine)
• 1 cup vegetable oil (or light olive oil for a fruity note)
• 1 teaspoon vanilla extract (the good stuff—none of that imitation vanilla!)

Dry Ingredients

• 2 cups all-purpose flour (spoon and level it—don’t scoop!)
• 1 teaspoon cinnamon (Vietnamese cinnamon is my secret for warmth)
• 1 teaspoon baking powder (check it’s fresh—old powder won’t rise right)
• 1/2 teaspoon baking soda
• 1/4 teaspoon salt (just a pinch balances the sweetness)

Frosting Ingredients

The frosting makes this cake special. Cream cheese must be room temp—I learned the hard way that cold cheese makes lumpy frosting!

• 3 1/2 cups powdered sugar (sift if it’s clumpy)
• 1 (8-oz) package cream cheese (full-fat only, and softened)
• 1/4 cup unsalted butter (also softened—30 minutes out of the fridge)
• 1 teaspoon vanilla extract (same as the cake batter)

How to Make Summer Squash Cake

Okay, let’s get baking! This Summer Squash Cake comes together in stages, but don’t worry—none of the steps are tricky. I’ve made this dozens of times, and once you get the rhythm down, it’ll become second nature. Just follow these simple steps, and you’ll have a gorgeous cake ready to frost before you know it!

Preparing the Cake Batter

First things first—preheat that oven to 350°F (175°C). While it’s heating up, grab your favorite mixing bowl (mine’s this chipped blue one that’s seen better days) and let’s make magic happen.

Start by whisking together the eggs, grated squash, sugar, oil, and vanilla extract. You want this mixture nice and smooth—no streaks of egg yolk visible. The squash will release some liquid as you mix, and that’s perfect! That moisture is what keeps this Summer Squash Cake so incredibly tender.

Now, add all your dry ingredients right on top—flour, cinnamon, baking powder, baking soda, and salt. Here’s my trick: use a fork to lightly mix the dry stuff together before folding it into the wet ingredients. This prevents any little baking soda or powder pockets from forming. Mix just until everything’s incorporated—overmixing makes tough cake, and we want fluffy!

Baking the Summer Squash Cake

Pour that beautiful batter into your greased 9- or 10-inch round pan. Smooth the top with a spatula—it’ll look lumpy from the squash, but that’s normal. Pro tip: place the pan on a baking sheet before putting it in the oven. This catches any potential overflow (trust me, I’ve had some messy oven incidents!).

Bake for 55-60 minutes. Around the 45-minute mark, start checking with a toothpick—insert it near the center, and when it comes out with just a few moist crumbs (not wet batter), you’re golden. The top should be a deep golden brown, and the edges will pull slightly away from the pan.

Here’s the hard part: let it cool completely in the pan on a wire rack. I know it smells amazing, but if you try to frost a warm cake, you’ll end up with a melty mess! About 2 hours should do it.

Making the Cream Cheese Frosting

While the cake cools, let’s whip up that dreamy frosting. In your stand mixer (or with a hand mixer), beat the softened cream cheese and butter together until they’re completely smooth—no lumps allowed! Scrape down the bowl frequently.

Add the vanilla, then dump in all the powdered sugar at once. Start mixing on low speed unless you want a powdered sugar cloud in your kitchen (been there!). Once it’s mostly incorporated, crank up the speed to medium-high for about 10 seconds—just until the frosting gets fluffy. Overbeating makes it too soft.

Assembling the Cake

Time for the fun part! Run a thin knife around the edge of your cooled cake to loosen it from the pan, then flip it onto a plate. If the top domed a lot, you can level it with a serrated knife—but I usually leave it rustic-looking.

Spread that luscious frosting thickly over the top, letting some drip down the sides prettily. No need to frost the sides fully—the naked cake look is totally in! Pop it in the fridge for about 30 minutes to let the frosting set before slicing.

And there you have it—Summer Squash Cake perfection! The hardest part now is waiting to dig in…

Why You’ll Love This Summer Squash Cake

This isn’t just any cake—it’s the kind of dessert that makes people ask for seconds (and then beg for the recipe). Here’s why it’s become my summer staple:

• Impossibly moist texture – The squash keeps every bite tender, even days after baking (if it lasts that long!)
• Secretly wholesome – Packed with fresh veggies, but sweet enough that kids devour it
• Garden-to-table magic – Perfect for using up that backyard squash overload in the tastiest way possible
• Foolproof to make – No fancy techniques needed, just simple mixing and baking
• Always a crowd-pleaser – The cream cheese frosting takes it from “nice” to “where has this been all my life?”
• Better the next day – Flavors deepen overnight, making it ideal for make-ahead gatherings

Seriously, this Summer Squash Cake checks all the boxes—it’s the dessert that makes summer taste even sweeter.

Tips for the Best Summer Squash Cake

After making this cake more times than I can count (and yes, learning from a few flops along the way), I’ve picked up some game-changing tricks. These little details take your Summer Squash Cake from good to “oh-my-goodness-I-need-another-slice” amazing!

Don’t squeeze your squash!

I know it’s tempting to wring out grated squash like you would with zucchini bread, but resist! That natural moisture is what makes this cake so tender. Just pat it lightly with a paper towel if it seems extra wet—you want about 2 cups of loosely packed, freshly grated squash for perfect texture.

The golden rule: mix gently

Overmixing is the enemy of fluffy cake. Once you add the dry ingredients, stir just until the flour disappears. A few small lumps are fine—they’ll bake out. I like to use a rubber spatula and fold in wide, gentle strokes. Your arm might get tired, but your taste buds will thank you!

Know your oven’s personality

Nothing’s worse than a sunken cake because your oven runs hot. Mine’s a feisty one—I always bake at 325°F instead of 350°F and add 5 extra minutes. Use an oven thermometer (they’re cheap!) to check accuracy. If the top browns too fast, tent it with foil after 40 minutes.

Let it cool—no cheating!

I get it—that warm cake smell is torture. But frosting a warm Summer Squash Cake is a recipe for sliding frosting puddles. Wait until the pan feels just warm, not hot, about 2 hours. Pro tip: Pop it in the fridge for 30 minutes if you’re impatient (I won’t tell).

Fresh spices make all the difference

That cinnamon should smell like heaven when you open the jar. If your spices are older than a year, treat yourself to new ones—they lose potency over time. I keep mine in the freezer to stay fresh longer. A pinch of nutmeg or cardamom adds lovely depth too!

Summer Squash Cake Variations

One of my favorite things about this Summer Squash Cake is how easily it adapts to different flavors and dietary needs. Over the years, I’ve played with all sorts of twists—here are my absolute favorite variations that still honor the original’s delicious spirit!

Going gluten-free? No problem!

Simply swap the all-purpose flour with your favorite 1:1 gluten-free blend (I love King Arthur’s). The squash keeps everything moist, so you won’t even miss the gluten. Just check that your baking powder is GF too—some brands sneak in wheat starch.

Nut lovers, rejoice!

Fold in 3/4 cup chopped pecans or walnuts into the batter for delightful crunch. Toasting them first brings out their flavor—just watch them carefully so they don’t burn! My aunt always adds a handful of golden raisins too for little bursts of sweetness.

Zesty citrus twist

Add 2 teaspoons lemon or orange zest to the batter for bright summer flavor. For extra punch, swap half the vanilla extract in both cake and frosting with citrus extract. A drizzle of lemon glaze instead of cream cheese frosting? Divine!

Spice it up your way

While cinnamon is classic, try adding 1/4 teaspoon cardamom or ginger for warmth. Chai lovers—mix in 1/2 teaspoon each cinnamon, ginger, and cardamom plus a pinch of black pepper. Sounds crazy, but trust me, it works!

Chocolate chip surprise

Because everything’s better with chocolate! Stir in 1 cup mini chocolate chips (regular chips sink). The melted pockets against the moist squash cake? Pure magic. Kids especially love this version.

The beauty of Summer Squash Cake is how forgiving it is—don’t be afraid to make it your own! Just keep that squash base and you’re golden. What variations have you tried? I’m always looking for new ideas to test!

Storing and Serving Summer Squash Cake

This cake disappears fast at my house—but if you somehow have leftovers (or want to bake ahead), here’s how to keep it tasting fresh and fabulous. The cream cheese frosting means you can’t just leave it on the counter like some cakes—trust me, I learned that lesson the hard way one summer afternoon!

Keeping it fresh in the fridge

Once frosted, your Summer Squash Cake needs refrigeration. I cover it loosely with foil or slide the whole cake stand into one of those giant plastic cake keepers. It’ll stay perfect for 4-5 days—though in my experience, it never lasts that long! The frosting actually helps seal in moisture, so slices stay tender.

Freezing for later (yes, it works!)

Need to stash some away? Freeze unfrosted cake layers wrapped tightly in plastic wrap, then foil, for up to 3 months. Thaw overnight in the fridge before frosting. You can freeze frosted slices too—just separate them with parchment in an airtight container. They thaw in about 30 minutes at room temperature.

Serving tips for maximum wow factor

Let refrigerated cake sit at room temperature for 20 minutes before serving—the flavors wake up beautifully. For special occasions, I garnish with edible flowers or lemon zest curls. A dusting of cinnamon takes it up a notch too! Warm individual slices for 10 seconds in the microwave if you prefer it slightly gooey (my husband’s favorite way).

Pro tip: Bring leftovers to room temp before refrigerating again. Repeated chilling draws out moisture and makes the texture gummy. Now go enjoy every last crumb of your Summer Squash Cake—you’ve earned it!

Summer Squash Cake FAQs

I get so many questions about this cake whenever I bring it to gatherings! Here are the answers to the most common ones—consider this your cheat sheet for Summer Squash Cake success.

Can I use only zucchini instead of a mix?

Absolutely! The combo of zucchini and yellow squash looks pretty, but all zucchini works great. Just make sure you’re using about 2 cups total. Yellow squash tends to be slightly sweeter, so if you’re using only zucchini, you might want to add an extra teaspoon of sugar—but honestly, most people can’t tell the difference!

Does this cake freeze well?

Better than you’d think! Freeze unfrosted layers wrapped tightly in plastic and foil for up to 3 months. Frosted slices freeze beautifully too—just layer them between parchment in an airtight container. They’ll taste fresh after thawing overnight in the fridge. The texture holds up shockingly well!

Can I make cupcakes instead?

You sure can! Fill lined muffin cups 2/3 full and bake at 350°F for 18-22 minutes. They’re adorable with a little swirl of frosting—perfect for summer picnics. You’ll get about 18 standard cupcakes from one batch. Check them early—they bake faster than the full cake.

Why did my cake sink in the middle?

Oh no! Usually that means either the baking powder/soda was old (they lose potency after 6 months), the oven temp was off (get that thermometer I mentioned!), or you opened the oven door too early. The cake needs that initial undisturbed heat to set properly. Wait until at least the 45-minute mark before peeking!

Can I reduce the sugar?

You can, but be careful—sugar adds moisture as well as sweetness. I’ve successfully reduced it to 1 cup without major texture changes. Any less and the cake gets dense. If you try it, maybe add a tablespoon of applesauce to keep things tender. The frosting definitely needs all its sugar though—it won’t set properly otherwise.

Nutritional Information

Okay, let’s talk numbers—but remember, these are just estimates! Your actual Summer Squash Cake nutrition might vary depending on your exact ingredients (like how much frosting you slather on—no judgment here!). I calculated this based on standard brands and 8 generous slices per cake.

• Serving Size: 1 slice (about 1/8 of the cake)
• Calories: 450 (worth every single one!)
• Sugar: 40g (mostly from that dreamy frosting)
• Sodium: 150mg
• Fat: 25g (6g saturated from the butter and cream cheese)
• Carbohydrates: 55g (with 1g fiber from all that squash goodness)
• Protein: 5g (who knew cake could have protein?)
• Cholesterol: 80mg

Now, before anyone panics about the numbers—remember, this is dessert! And it’s packed with actual vegetables, which makes me feel slightly virtuous when I go back for seconds. The values will change if you use sugar substitutes, low-fat cream cheese, or different oils. My philosophy? Life’s too short to stress over cake calories—just enjoy every delicious bite!
