Birthday Cake Oreo Truffle Blondies
A beautiful collision of Cake Batter and Funfetti that begins with a chewy, moist, sprinkle-laced blondie, followed by a thick and rich layer of Birthday Cake-flavored Oreo truffle and a finale of cream cheese buttercream--a sprinkle lover's dream!
Ingredients
For the Blondie Layer
- 1 box yellow cake mix (I used Duncan Hines)
- ½ cup sprinkles
- ⅓ cup vegetable oil
- ¼ cup milk
- 1 large egg
For the Truffle Layer
- 1 (15.25 oz) Golden Birthday Cake-Flavored Oreos
- 6 ounces cream cheese softened
- ¼ cup sprinkles
For the Cream Cheese Frosting
- ½ cup unsalted butter softened
- 4 ounces cream cheese
- ½ cup powdered sugar
- ½ teaspoon vanilla
- Pinch of salt
- Sprinkles for decorating
Instructions
- Preheat oven to 350ºF and spray an 8x8 inch square dish with nonstick cooking spray.
- In a large mixing bowl, combine the cake mix and sprinkles. Add the oil, milk, and egg, and stir until thick batter forms.
- Pour batter into prepared pan and bake in the oven for 25-28 minutes, or until edges are slightly golden. Allow to cool completely.
- In a food processor, process Oreos into fine crumbs. Add the cream cheese and process until fully incorporated. Stir in sprinkles.*
- Using the back of a spatula or your fingers, press Oreo truffle mixture into an even layer on top of the cooled blondies.
- In a stand mixer fitted with a paddle attachment, mix the butter and cream cheese together until smooth and fully blended. Add the powdered sugar, vanilla, and salt and mix until just combined.
- Spread cream cheese frosting evenly on top of the Oreo truffle layer. Add sprinkles. Cut into squares and serve! Blondies will stay fresh wrapped in plastic wrap or covered in an airtight container for up to 1 week in the refrigerator.
Notes
*If you don't have a food processor, you can crush the Oreos in a large zip-top bag with a rolling pin. Once evenly crushed, pour Oreo crumbs into a large bowl and stir the cream cheese and sprinkles in with a spoon until well-blended.
