Perfect gluten-free cake for summer!
Summer is all about spending time outdoors – or ya know, on patios – watermelon, cookouts, and hot weather. But why does that mean cake can’t come to the party?
This little cake is a subtle nod to that popular summer holiday in the states, whether you call it 4th of July, Independence Day, or Firecracker Day (really, I’ve heard it all!). With strawberries and blueberries baked within and topping the cake, it’s a nice little tribute to America.
I’m all about transparency, so the story behind this cake recipe is this: I thought this gluten-free cake was going straight to the trash. Really.
For the first time ever, my frosting failed, the cake fell in, it took way too long to bake, and I was ready to taste the cake and immediately dump it.
But I didn’t.
Because it turned out amazing.
If you’re someone who isn’t a fan of frosting, this is the cake for you. If you’re someone who loves frosting and can eat it right out of the bowl (hi, that’s me), this is the cake for you, too. If you want an excuse to eat cake in the summer, this is for you, too.
I adapted this recipe from Gluten-Free on a Shoestring’s basic vanilla cake; however, I made some major modifications to this gluten-free cake recipe thanks to the berries, my desire to make it a little less sweet, and my genuine screw-ups along the way.
I have one major tip when baking, because I always wanted to make cute little 6″ cakes, but until recently, didn’t have the cute little pans:
Never make enough batter for an 8″ cake pan and pour it into 6″ cake pans. Just don’t do it! Even by accident! You’ll regret your whole life!
Okay, you won’t regret your whole life, but your cake will take forever to bake and will become slightly dry. And your husband or wife will be forced to eat an entire bowl-full of the extra gluten-free cake you had to slice off the top.
This cake isn’t your super-sweet, give-you-a-headache, covered-in-frosting cake. It has a light, airy sweetness thanks to the dusting of powdered sugar and strawberry and blueberry puree within the cake.
It even tastes delicious warm, room temperature or cool.
When you top this cake with the berry purees, it gives it a slightly tangy and satisfying bite that’s unlike other cakes, making it perfect for late spring or the hot days of summer.
2 cups Bob’s Red Mill Gluten Free 1-to-1 baking flour
1/4 cup + 2 tablespoons cornstarch
1/2 teaspoon baking soda
2 teaspoons baking powder
1/2 teaspoon kosher salt
12 tablespoons unsalted butter, at room temperature
1 1/4 cups granulated sugar
1/2 cup powdered sugar
2 teaspoons pure vanilla extract
4 egg whites + 1 whole egg at room temperature
1 1/4 cups buttermilk at room temperature*
*If you’re like me and always forget buttermilk, here’s an easy substitute: Add 1-1.5 tablespoons lemon juice to regular milk, stir and let rest for 5-10 minutes. You’ll see it slightly curdle – that’s good. Stir before mixing with other ingredients.
5-8 strawberries, depending on size
1 cup blueberries
Pre-heat oven to 350. Grease two 8″ or three 6″ baking pans and place parchment paper cut to fit in the bottom.
In a medium bowl, sift flour, cornstarch, baking soda and baking powder. Add salt and whisk.
In a large bowl or bowl attached to a stand mixer, add butter, granulated sugar and vanilla. Mix on medium-high for 3 minutes until fluffy. You may need to scrape the mixture off the sides of the bowl halfway through.
Combine the egg whites, egg and buttermilk (or buttermilk substitute) into a bowl and whisk to combine.
Add the dry ingredients in 4 equal portions into the bowl with butter, sugar and vanilla, alternating with the milk and egg mixture. Mix between adding portions.
Continue to beat ingredients on medium speed until everything is fully combined and smooth.
Divide the batter into two (for 8″ pans) or three (for 6″ pans) and pour into medium-sized bowls.
In a food processor, chop up the strawberries until they’re mostly smooth – a few larger pieces are just fine. Pour half of the berry purée into one (for 8″ pans) or two (for 6″ pans) bowls of batter. Mix by hand to combine. Set the remaining berry purée aside for topping later.
Repeat the processing steps for the blueberries, adding a little less than half of the purée to the remaining pan(s). Set the remaining purée aside for topping.
Pour mix into pans until they’re filled evenly. Place the baking pans into preheated oven and bake for 20 minutes, until a toothpick is clean and they are golden brown.
Remove the cakes from the oven and cool the cake in pans for 10-20 minutes before placing cakes onto a wire rack. Remove parchment paper and allow to cool completely.
To assemble the gluten-free cake, place on a stand, serving platter or plate. Place the first layer on the surface, then spread 1-2 tablespoons one of the berry purées on top until covered, but not dripping down the sides. Place the alternating flavor cake on top of the first layer. If using 3 6″ layers, spread the other berry purée and place the third layer on top.
If serving immediately, sift desired amount of powdered sugar on top and sides of cake. If serving later, wait until serving time to dust powdered sugar, since it will melt into the cake within a few hours.
Optional: Spread a tablespoon of each purée on center of cake, then top with berries or spread berry purée on individual pieces. Mix berry purée with cream cheese frosting and use between layers instead of puree-only.
This cake looks amazing!
Thanks, Kimberly! Tastes amazing, too. Glad to see a fellow Okie 🙂
