Equipment
- 9-inch cake pans
- Wax paper
- large bowl
- Small saucepan
- Wire cooling rack
- Serrated Knife
Ingredients
Cake:
- 1 box white cake mix
- 1 3-ounce package strawberry flavored Jell-O
- 3 tablespoons flour
- 1 cup butter
- 0.5 cup cold water
- 16 ounces package frozen strawberries (thawed)
- 4 eggs
Icing:
- 8 ounces butter (softened)
- 1 pound powdered sugar
- 8 to 10 ounces strawberries diced or blended into a purée
Instructions
Pan Prep and Batter Setup
- Line two 9-inch cake pans, or three 8-inch pans, with wax paper, then preheat the oven to 350 degrees F to ensure a clean release for your layers.
- In a large bowl, whisk together the dry cake mix and flour so the flour disperses evenly to avoid dense pockets.
The Strawberry Reduction Twist
- Puree the 16 ounces of thawed strawberries, then simmer the puree in a saucepan until it reduces by half to concentrate the flavor and remove excess moisture.
- Measure out 1/2 cup of the strawberry reduction and stir it into the strawberry flavored Jell-O until glossy and fully blended.
Mix, Bake, and Cool
- Add the dry cake mix and flour mixture into the strawberry base, then beat until the batter looks smooth and evenly pink.
- Add the eggs one at a time, mixing until each disappears before the next goes in to ensure a satiny emulsion.
- Add the butter and any remaining thawed strawberry bits, then beat until the batter falls from the beater in thick ribbons.
- Divide the batter evenly between the prepared pans and bake for 15 to 20 minutes. Test the center with a toothpick; it should come out clean.
- Cool the cake layers completely on a wire cooling rack so the crumb sets and the frosting won’t melt upon application.
Strawberry Butter Icing and Assembly
- Beat the softened butter, then add the powdered sugar and strawberries, mixing until the icing turns creamy and spreadable.
- Level the cooled layers using a serrated knife, then frost and stack. Chill the assembled cake briefly to help the layers settle.
Notes
Moisture Control: Reducing the strawberry puree concentrates flavor and sugars while removing excess water, which prevents the box mix from sinking in the middle.
Emulsification Tip: Bringing butter and eggs to room temperature allows them to blend smoothly into the batter, preventing a curdled appearance and ensuring an even bake.
Storage: Keep the cake in the refrigerator for up to 4 days. The strawberry flavor deepens after 24 hours in the fridge, making it a perfect make-ahead dessert.
