Line 2, 8-inch cake pans with parchment paper and grease the sides well. Set aside.
Process freeze-dried strawberries in a food processor or blender until they are a fine powder.
Combine flour, baking powder, and salt in bowl, whisk to combine and then set aside.
In a large mixing bowl, using a hand mixer or your stand mixer, cream butter and sugar together until light and fluffy, about 3 minutes.
Add eggs and mix well to combine.
Add ⅓ of the flour mixture and mix until incorporated.
Add half of the milk and mix until incorporated.
Add another third of the flour and mix.
Add remaining milk and mix.
Add remaining flour and mix until a smooth batter forms.
Add powdered freeze-dried strawberries and mix to full combine.
Divide the batter into prepared bans and bake for 30-35 minutes or until the cake springs back lightly when touched and a toothpick inserted into the center comes out clean. Place the warm cakes on a cool wrack and let them rest for 10 minutes in the pan before removing from the pan.
We frosted the cake with our strawberry frosting and also used that in-between the layers. You could also put strawberry jam, a strawberry reduction, or whipped cream and sliced strawberries in-between the layers of cake. You have lots of good options!
Freeze dried strawberries are my favorite trick for making strawberry cake! They pack a ton of flavor without the added moisture from fresh strawberries which can we hard to work with. You can find them in the snack isle at most large stores (Walmart carries them).
