Cuisine: American
Serves: 16 servings
Ingredients
- 1 cup unsalted butter
- 1 cup brown sugar
- 1/2 cup granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 1 cup Birthday Cake Oreos, chopped
Instructions
- Preheat the oven to 350°F (175°C). Line a 9x9-inch baking pan with parchment paper, allowing excess paper to hang over the sides for easy removal.
- In a large microwave-safe bowl, melt the unsalted butter completely. Allow it to cool slightly for 2-3 minutes.
- Whisk the brown sugar and granulated sugar into the melted butter until well combined and slightly smooth.
- Add the eggs one at a time, mixing thoroughly after each addition. Stir in the vanilla extract until the mixture is smooth and glossy.
- In a separate bowl, whisk together the all-purpose flour, baking powder, and salt to ensure even distribution of leavening agents.
- Gradually fold the dry ingredients into the wet mixture, stirring until just combined. Be careful not to overmix the batter.
- Roughly chop the Birthday Cake Oreos into chunks, reserving some for topping.
- Gently fold most of the chopped Oreos into the blondie batter, leaving a few pieces for garnishing the top.
- Pour the batter into the prepared baking pan, spreading it evenly with a spatula. Sprinkle the remaining Oreo chunks on top.
- Bake in the preheated oven for 25-30 minutes, or until the edges are golden and a toothpick inserted into the center comes out with a few moist crumbs.
- Remove from the oven and let cool completely in the pan for about 1 hour. Use the parchment paper to lift the blondies out and cut into 16 square pieces.
- For best results, store in an airtight container at room temperature for up to 5 days. The blondies can also be frozen for up to 2 months.
Tips
- Use room temperature eggs for a smoother, more consistent batter
- Don't overmix the batter - this can lead to tough, dense blondies
- Make sure to line your pan with parchment paper for easy removal
- Reserve some Oreo chunks for topping to create a visually appealing dessert
- Let the blondies cool completely before cutting to ensure clean, neat squares
- For extra richness, you can add a drizzle of white chocolate or sprinkle some colorful birthday cake sprinkles on top
- Check your blondies a few minutes early to prevent over-baking - you want them slightly soft in the center
