FAQs

1. Can I make Peanut Butter Brownies ahead of time?

Yes! These brownies can be made a day in advance and stored in an airtight container at room temperature for 2–3 days. For longer storage, wrap them tightly and refrigerate for up to a week, or freeze for up to 3 months.

2. Can I use natural peanut butter instead of creamy peanut butter?

Absolutely! Natural peanut butter works well, but it may be slightly less sweet and more runny. Warming it slightly before swirling into the batter can help it spread and marble more easily.

3. How do I make fudgier Peanut Butter Brownies?

For extra fudgy brownies, reduce the baking time by 3–5 minutes and avoid overmixing the batter. Slightly underbaked brownies will remain soft and gooey in the center.

4. Can I make these brownies gluten-free?

Yes! Substitute the all-purpose flour with a gluten-free flour blend or almond flour. Be mindful that almond flour may slightly alter the texture, making brownies denser but still delicious.

5. Can I add extra chocolate to the recipe?

Definitely! Chocolate chips, chunks, or even white chocolate can be folded into the batter for added richness. Sprinkle some on top before baking for a gooey chocolate layer.

Conclusion

Peanut Butter Brownies are a timeless treat that blends the richness of chocolate with the creamy, nutty flavor of peanut butter.
