Preheat oven to 350°F. Coat an 8-inch square baking pan with cooking spray.
Combine 2½ cups oats, ¾ cup protein powder, ¼ cup sugar, 2½ tablespoons cocoa, 2 tablespoons chocolate chips, ½ teaspoon espresso granules and ¼ teaspoon salt in a medium bowl; stir until well blended.
Combine 1 cup soy milk, 1 cup cottage cheese and 2 cups strawberries in a blender; blend until smooth, about 1 minute. Pour the strawberry milk mixture into the bowl with the oat mixture. Stir in beaten eggs and 2 teaspoons vanilla until well combined. Pour the mixture into the prepared pan, spreading it into an even layer. Top with the remaining ½ cup strawberries.
Bake until a toothpick inserted in the center comes out clean, about 40 minutes. Cool on a wire rack for 15 minutes before slicing.
