How to Make Peanut Butter Brownies

- Line your 8×8 inch square tin with parchment paper.
- Pour the brownie batter evenly into the tin.

- Drizzle peanut butter over the batter. I did two spoons, but if you love peanut butter, feel free to add extra!

- Preheat your oven to 320°F (160°C) and bake for 15-18 minutes or until a toothpick inserted in the center comes out clean.
- Let it cool on a rack before cutting into squares.

Tips for the Best Peanut Butter Brownies
- Use Smooth Peanut Butter: It gives the best texture and swirl.
- Nail The Perfect Swirl: Use a toothpick or knife to gently swirl the peanut butter into the batter before baking.
- Don’t Overbake: Brownies should be slightly gooey in the middle.
- Sprinkle Some Salt: A pinch of sea salt on top brings out the flavors.
- Add Extras: Throw in some chocolate chips or chopped peanuts for extra crunch.
How to Store & Reheat
- Room Temperature: Keep in an airtight container for up to 3 days.
- Refrigerator: Store for up to a week.
