Preheat oven to 350 degrees F. Prepare a 10 x 5 loaf pan with cooking spray. In a food processor, pulverize the freeze dried strawberries, until a fine powder forms. Set aside.
1 cup freeze dried strawberries
In a medium mixing bowl, combine flour, baking powder and baking soda with a whisk. Set aside.
2 cups all-purpose flour, 1 tsp baking powder, 1 tsp baking soda
In a separate, large mixing bowl, beat the butter sugar until smooth and creamy. Add eggs and vanilla extract; mix until combined.
1 cup butter, softened, 1 cup granulated sugar, 4 large eggs, 2 tsp vanilla extract
Add flour mixture, alternating with the evaporated milk to the wet ingredients. Beat together until just combined. Do not overmix. Transfer half of the batter into a separate, medium-sized, mixing bowl and fold in strawberry powder and food coloring.
1/2 cup evaporated milk, red food coloring (optional)*
Using an ice cream scoop, scoop the strawberry and vanilla batter in a checkerboard pattern into the bottom of the pan. Tap the pan on the counter to settle the batter. Create another layer of the checkerboard pattern with the opposite batters on top of each other. (See picture in post above for an example and make sure to read my marbled swirling tutorial in the above post.) Tap the pan on the counter again. Use the end of a wooden spoon to swirl batters together. Tap pan again on the counter. Bake for 55-60 minutes, or until a toothpick comes out clean from the middle.
When the cake comes out of the oven, place pan on a cooling rack for about 15 minutes before removing the from the pan. Cool completely.
