Raspberry Zinger Cake with a homemade vanilla sheet cake, raspberry filling, marshmallow frosting, and pink coconut topping. One bite will bring you back to that box of Hostess, but this one is better!
Preheat oven to 350 degrees F. Grease and flour a 13x9 baking dish, or use baking spray. Set it aside.
In a large mixing bowl, beat butter with granulated sugar for several minutes, until butter turns pale in color. Add in eggs, egg whites, and vanilla extract. Beat an additional 2-3 minutes, scraping down the sides of the bowl as needed.
Add in cake flour, salt, and baking powder, Mix just until combined.
Add buttermilk. Beat for a minute or two until fully blended. Pour batter into baking dish.
Bake for 40-44 minutes, or until a toothpick inserted into the center comes out with just crumbs. Poke about 20 holes in the top of the warm cake with the back of a wooden spoon. Spread the raspberry preserves over the top while the cake was still warm.
In a mixing bowl, beat marshmallow fluff with butter for 3 minutes. Add in vanilla and powdered sugar and beat for about 3 minutes. Frosting with be thick, almost like a taffy texture. Drop onto the raspberry preserves and spread using an offset spatula or fingertips.
In a bowl, add coconut and gel food coloring. Mix with a fork until all the coconut has been tinted. Add an additional drop or two to achieve desired color. Spread coconut over cake.
Notes
If you prefer to use a cake mix, you can swap out the homemade vanilla sheet cake for a yellow cake or butter cake instead!
Save your two leftover egg yolks to make my homemade lemon curd recipe or my drop sugar cookies.
I used an 18 ounce jar of Raspberry preserves, which is about 1 3/4 cups.
Storage- cover cake with plastic wrap and keep in the refrigerator for up to 5 days.
