- 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.
