Top Tips for Perfecting Stuffed Peanut Butter Brownies
- Substitutions: If you’re looking to switch up the flavor, consider using almond butter or any nut butter that’s your favorite!
- Timing: Keep an eye on your brownies as they bake. They might need an additional minute or two depending on your oven, but avoid overbaking to maintain that fudgy texture.
