Peanut Butter Brownie Bites in 35 Minutes

Instructions:

1. Whisk the melted butter and granulated sugar together until combined. Add eggs and vanilla, stirring until the mixture is glossy.
2. Sift in the cocoa powder, flour, and salt; fold gently with a spatula until the flour is barely incorporated, avoiding over-mixing.
3. In a small bowl, blend the creamy peanut butter, powdered sugar, and melted butter until a stable paste forms.
4. Spray a mini muffin tin with non-stick baking spray. Spoon approximately 1 tablespoon of brownie batter into each cup.
5. Drop a small dollop (approximately 1/2 tsp) of the peanut butter mixture into the center of each brownie base.
6. Top with a small amount of additional brownie batter to seal the peanut butter core.
7. Bake at 350°F (175°C) for 18-22 minutes, or until the edges are set and a toothpick inserted into the center comes out with a few moist crumbs.
