Cake Batter Oreo Protein Blondies

Cake Batter Oreo Protein Blondies are dense, moist bars combining protein powder with classic blondie ingredients and fun sprinkles. Oreo Thins add chocolate creaminess layered in the center, while white chocolate chips and rainbow sprinkles lend texture and bursts of sweetness. The batter includes Greek yogurt and applesauce for moisture, resulting in a rich, slightly underbaked blondie that sets well after chilling overnight.

Description

This blondie recipe uses a blend of protein powder, all-purpose flour, sweeteners, baking agents, Greek yogurt, applesauce, cake batter extract, peanut butter, and butter to create a thick batter with balanced richness and subtle cake batter flavor. After mixing dry and wet ingredients, half the batter is baked, topped with Oreo Thins, then covered with remaining batter and sprinkled with white chocolate chips and sprinkles.

Baking at 325°F for 30 minutes until a toothpick inserted is mostly clean ensures a moist, dense texture once cooled. The blondies firm up after chilling overnight, which enhances flavor melding and creates the desired chewy, gooey consistency. The combination of chocolate, cookie, and vanilla notes provides an indulgent treat with added protein content.

These blondies are suitable as a sweet snack or dessert, especially for those looking to increase protein intake. They are best stored in an airtight container in the refrigerator and served chilled for optimal texture and flavor release.

Careful measuring and avoiding overbaking are key to achieving the right texture. The recipe advises allowing the blondies to set overnight to develop structure and flavor fully.

Ingredients

Servings
  • 1/2 cup protein powder 60g) or replace with more flour, vanilla
  • 3/4 cup all-purpose flour 90g
  • 1/4 cup granular sweetener (48g)
  • 2 Tbsp brown sugar sweetener (24g)
  • 1/2 tsp baking powder
  • 1/4 tsp baking soda
  • 1/4 tsp salt
  • 1/2 cup Greek yogurt plain, 112g
  • 1/2 cup applesauce unsweetened, (122g
  • 2 tsp cake batter extract
  • 2 Tbsp peanut butter 28g
  • 2 Tbsp butter or regular butter, softened, light, 28g
  • 2 Tbsp Rainbow sprinkles divided, 24g
  • 16 Oreo thins 116g
  • 1 Tbsp white chocolate chips 14g

Instructions

  1. Preheat the oven to 325 degrees F. Line a 8x8-inch baking dish with parchment paper and/or spray with nonstick cooking spray.
  2. In a large bowl, add the protein powder, flour, sweetener, brown sugar, baking powder, baking soda, and salt. Mix to combine. Then, add the yogurt, applesauce, vanilla, peanut butter and butter. Combine everything with a hand mixer. Stir in 1 tablespoon of sprinkles.
  3. Pour half of the blondie batter into the prepared dish. Place the Oreos on top. Then pour the remaining blondie batter on top. Sprinkle with white chocolate chips and the remaining Tbsp of sprinkles.
  4. Bake for 30 minutes, or until a toothpick inserted in the center comes out mostly (but not completely!) clean. We want to take these out when they are still slightly underdone. They will continue to set in the hot pan once removed from the oven and this ensures we don't over-bake them! Slightly underdone results in BEST final texture. Let cool completely before cutting. If you prefer them cold (I do!), go ahead and store them in the fridge, covered, and cut into bars when you are ready to eat. They will be easier to cut the longer they have set.

Notes

  • Measure ingredients accurately to maintain balance and texture, especially when using protein powder.
  • Remove blondies from oven slightly underdone to allow residual heat to finish baking and preserve moistness.
  • Chill blondies overnight in an airtight container to let flavors develop and texture set firmly before cutting and serving.
