Baking Tips for the Best Peanut Butter Cookie Brownies
- Use Room Temperature Ingredients: Make sure your butter and peanut butter are at room temperature for easier mixing and a smoother batter.
- Don’t Overmix the Brownie Batter: To keep your brownies fudgy and dense, mix just until everything is combined.
- Chill the Crumble Dough: If the dough feels too soft to crumble easily, chill it in the fridge for 10-15 minutes before topping the brownies.
- Allow Cooling: Let the brownies cool completely in the pan before cutting them. This will help them set perfectly and make them easier to slice.
