Tips to Make Peanut Butter Stuffed Brownies
- Use smooth peanut butter for a creamy filling, but crunchy peanut butter will add a fun texture.
- Make sure your butter and chocolate mixture is cool before adding eggs to prevent them from cooking.
- Don’t overmix the brownie batter after adding the dry ingredients for the best texture.
Variation
You can add mix-ins like chopped nuts, caramel, or more chocolate chips to the brownie batter for added flavor. If you want a healthier version, substitute the all-purpose flour with whole wheat flour and use less sugar.
FAQs
1. Can I use natural peanut butter instead of smooth peanut butter?
Yes, but natural peanut butter can be more runny. Make sure to stir well to combine and consider adjusting the amount to achieve the right consistency.
2. How can I tell when the brownies are done?
Insert a toothpick into the center of the brownies. They should come out with a few moist crumbs for the best fudgy texture.
3. Can I make these brownies ahead of time?
Absolutely! You can prepare them a day in advance. They taste just as great after being stored. It might even enhance the flavors!
