Ingredients
For the Brownie Muffins:
- ¾ cup granulated sugar
- ¼ cup unsalted butter softened
- 1 tbsp water
- 1 cup semi-sweet chocolate chips divided
- 1 large egg
- ½ tsp vanilla extract
- 1 cup all-purpose flour
- ¼ tsp baking soda
- ¾ cup milk chocolate chips
For the Peanut Butter Filling:
- ¾ cup creamy peanut butter melted
Instructions
- In a microwave-safe bowl, combine sugar, butter, and water. Microwave for 45 seconds or until butter is melted. Stir well.
- Stir in ¾ cup semi-sweet chocolate chips until mostly melted. Then, mix in the egg and vanilla extract until smooth.
- In a separate bowl, whisk flour and baking soda. Gradually fold into the wet mixture until just combined—do not overmix!
- Let the batter cool for 10–15 minutes, then stir in milk chocolate chips and remaining ¼ cup semi-sweet chocolate chips.
- Spoon batter into a greased muffin tin and bake at 350°F (175°C) for 13–15 minutes, until a toothpick comes out with moist crumbs.
