How to Store Peanut Butter Brownies
To keep your brownies fresh, store any leftovers in an airtight container at room temperature. They will stay good for about 3 to 4 days. If you need to keep them longer, you can freeze them. Wrap individual pieces tightly in plastic wrap and place them in a zip-top freezer bag. They can be stored this way for up to 3 months. When you’re ready to enjoy, just thaw them at room temperature and they’ll be ready to eat.
Recipe Tips
- Make sure not to overmix the batter; just mix until combined for a fudgy texture.
- Let the brownies cool completely before slicing. This helps them set.
- If you want a richer flavor, consider adding a pinch of espresso powder to the batter.
- For a fun twist, try using crunchy peanut butter instead of creamy.
- If you like nuts, add chopped walnuts or pecans into the batter for extra crunch.
Variations & Swaps
- Swap the peanut butter for almond butter or sunflower seed butter for a different taste.
- Add chocolate chips to the batter for extra melted chocolate sweetness.
- For a festive version, fold in mini candy corn or seasonal sprinkles.
