Strawberry Cake
Preheat oven to 350F (175C). Grease and flour a 9x13 inch baking pan.
In a large bowl, whisk together the flour, sugar, baking powder, and salt.
Add the softened butter and beat with an electric mixer until the mixture resembles coarse crumbs.
In a separate bowl, whisk together the eggs, milk, and vanilla extract.
Gradually add the wet ingredients to the dry ingredients, mixing until just combined. Do not overmix.
Stir in the ground freeze-dried strawberries (and food coloring, if using).
Pour the batter into the prepared pan and spread evenly.
Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean.
Let the cake cool in the pan for 10 minutes before inverting it onto a wire rack to cool completely.
Freeze-Dried Strawberry Frosting
In a large bowl, beat the softened butter with an electric mixer until light and fluffy.
Gradually add the powdered sugar, beating on low speed until combined.
Add the ground freeze-dried strawberries, milk (or heavy cream), and vanilla extract.
Beat on medium-high speed until the frosting is smooth and creamy. Add more milk if needed to reach desired consistency.
Assembly
Once the cake is completely cooled, frost evenly with the freeze-dried strawberry frosting.
Optional: Garnish with fresh strawberries or additional freeze-dried strawberry powder.
Tips: For a more intense strawberry flavor, add 1 teaspoon of strawberry extract to the batter. To make a layer cake, divide the batter evenly between two 8-inch or 9-inch round cake pans and reduce the baking time accordingly. For a dairy-free option, use plant-based butter and milk substitutes. If you don't have freeze-dried strawberries, use strawberry jam instead for the batter and frosting, but reduce sugar for the best result.
