first of all, oh my gawd this cake was so huge. you better have a big mixing bowl to make this! everything didn’t fit into the food processor at once, so i just kinda disregarded the instructions and mixed all the wet ingredients + butter (and added a lil splash of vanilla extract), and then mixed those into the dry ingredients. also, i needed two bowls to make it work, which was a lil crazy. but it turned out pretty yummy! oh, and i was too lazy to make frosting so i bought whipped vanilla icing– it took almost 3 containers! and i dyed some of it pink with food dye to decorate the cakesies.
For the cake
4 1/2 cups cake flour
3 cups sugar
5 1/4 teaspoons baking powder
3/4 teaspoon salt
3 sticks (12 ounces) unsalted butter, at room temperature
1 1/2 cups pureed frozen strawberries*
8 egg whites
2/3 cup milk
1 to 2 drops red food dye, if using (to make the pink color pop more)
Make the cake
1. Preheat the oven to 350»F. Butter three 9-inch round or 8-inch square cake pans. Line with parchment or waxed paper and butter the paper.
2. Put the flour, sugar, baking powder, and salt in a large mixer bowl. With the electric mixer on low speed, blend for 30 seconds. Add the butter and strawberry puree and mix to blend the ingredients. Raise the speed to medium and beat until light and fluffy, 2 to 3 minutes; the batter will resemble strawberry ice cream at this point. (Deb note: I must warn you not to try the batter at this point. Not even a smear of it. How unbearably good it is will shock you, and lead to more dipping. Only you can stop this from coming to pass.)
3. In another large bowl, whisk together the egg whites, milk and red food dye, if using, to blend. Add the whites to the batter in two or three additions, scraping down the sides of the bowl well and mixing only to incorporate after each addition. Divide the batter among the three prepared pans.
4. Bake the cakes for 30 to 34 minutes, or until a cake tester or wooden toothpick inserted into the center comes out clean. Allow the layers to cool in the pans for 10 to 15 minutes. Invert and turn out onto wire racks and peel off the paper liners. Let stand until completely cooled before assembling the cake, at least an hour.
