Those freeze dried strawberries are my secret weapon The berry flavor is so intense that even a small amount transforms the buttercream My little cousin once asked if the frosting was made from magic That pretty much sums it up for me

Storage Tips

Store the cake covered in the refrigerator because of the fresh fruit filling For the softest crumb bring slices to room temperature before serving If you need to make it ahead wrap the cooled layers tightly in plastic and freeze without frosting

Ingredient Swaps

If you do not have cake flour use all purpose flour plus cornstarch as listed If you cannot find freeze dried strawberries substitute a tablespoon of strawberry jam for a lighter pink flavor Just know the frosting will be softer

Serving Suggestions

This cake is happiest at celebrations Set it out with extra berries and sprinkles on the side Serve petite slices for tea parties or hearty wedges for birthdays It also makes a charming centerpiece for spring brunch

A Slice of Funfetti History

Funfetti cakes first became popular in the early 1990s when boxed sprinkle cakes hit grocery shelves Adding those colored jimmies by hand gives you the same whimsical effect with richer homemade flavor Strawberry variations are less common but the berry filling and frosting make this version unforgettable

Frequently Asked Questions

→ How do you ensure fluffy cake layers?

To achieve light cake layers, make sure to properly whip the egg whites to stiff peaks and gently fold them into the batter. Creaming the butter and sugar thoroughly also helps create airy texture.

→ What is the best way to get intense strawberry flavor?

Use fresh strawberries for the filling and freeze-dried strawberries in the buttercream. This combination gives both tang and concentrated berry flavor.

→ Can I use a different kind of sprinkles?

Jimmies (cylindrical sprinkles) work best as they keep their color and shape in the batter. Other types may bleed or melt during baking.

→ How should the dessert be stored?

Because of the fresh strawberry filling, keep leftovers refrigerated. Allow the cake to come to room temperature before serving for ideal texture.

→ Is cake flour required for the batter?

You can use a mix of all-purpose flour and cornstarch or substitute cake flour for an even softer crumb. Both methods will yield a tender result.

Instructions

Step 01

Preheat oven to 350°F (175°C) and grease two 8-inch or 9-inch round cake pans. With a standing or hand mixer, whip egg whites until they reach stiff peaks and set aside.

Step 02

Cream butter using a mixer until light and fluffy, about 1-2 minutes. Add canola oil and granulated sugar, beating for another 1-2 minutes.

Step 03

Sift together flour, cornstarch, salt, and baking powder in a separate bowl.

Step 04

Alternately add dry ingredients and milk to the butter mixture, beginning and ending with the dry ingredients. Mix until combined. Fold in vanilla extract, almond extract, and sprinkles. Gently fold in egg whites until fully incorporated.

Step 05

Divide batter evenly between the prepared pans, spreading in an even layer. Bake for 20-22 minutes or until a toothpick inserted in the middle comes out clean. Allow cakes to cool completely.

Step 06

In a medium saucepan, mix strawberries, sugar, lemon juice, and flour. Cook over medium heat until it begins to boil, then reduce to medium-low and simmer for 10-12 minutes until thickened. Cool completely.

Step 07

Using a mixer, beat butter for 3-4 minutes until light and fluffy. Gradually add powdered sugar, one-half cup at a time, until frosting thickens. Mix in 3 tablespoons of heavy cream. Add crushed freeze-dried strawberries and incorporate. Adjust consistency with remaining powdered sugar or heavy cream as needed. Add a pinch of salt, if desired.

Step 08

Place one cake layer on a serving plate. Spread a thin layer of frosting on top. Pipe a thick border of frosting around the edge to create a barrier. Spoon the strawberry filling into the center. Cover the filling with a thin layer of frosting, spreading evenly. Place the second cake layer on top. Frost the cake with the remaining buttercream and decorate with strawberries and sprinkles.

Step 09

Serve the cake at room temperature. Refrigerate leftovers due to fresh fruit filling. Allow cake to come to room temperature (about 30-60 minutes) before serving again.

Notes

  1. Substituting 2 1/4 cups of cake flour can replace all-purpose flour and cornstarch for a softer texture.
  2. For best results, allow refrigerated cake to warm before serving.
