Peanut Butter Swirl Mini Brownies

My son and I wanted to make something special for my daughter’s after-school treat today. We finally decided to make peanut butter swirl brownies. I found this recipe on Ezra Pound Cake that looked delicious but I adapted it to make little mini brownies using mini muffin tins. My son had a great time stirring up all the ingredients and an even better time gobbling up the tasty brownie bites. My daughter was thrilled to come home from her first day of 2nd grade to find these little brownie bites, fresh from the oven, waiting for her. Both of my kids loved these brownies and so did my husband.

How to Make Peanut Butter Swirl Mini Brownies

Preheat the oven to 325 degrees. Coat three mini muffin pans with cooking spray.

For the brownie batter, put the butter and both chocolates in a heatproof bowl set over a pan of simmering water, stir until melted. Let cool slightly. Add the sugar and stir; add the eggs and vanilla then whisk until well combined. Mix the flour, salt, and baking powder in a bowl. Add the flour mixture to the chocolate mixture then mix well.

For the peanut butter filling, stir together the melted butter, powdered sugar, peanut butter, salt, and vanilla in a bowl until smooth and creamy.
