Prep & Preheat

Make the Brownie Batter

- Place one mini peanut butter cup in the center of each cup, gently pressing down.
- Add a teaspoon of creamy peanut butter over each peanut butter cup.
- Spoon remaining brownie batter on top, covering the peanut butter layers.
Bake & Cool

- Let cool in the pan for 10 minutes, then gently transfer to a wire rack to cool completely.
Notes
- Let the brownie cups cool completely before removing to prevent cracking.
- For a gooier center, bake on the lower end of the time range.
- Spray your muffin tin well to help keep the cups from sticking.
Variations

FAQ
Can I use homemade brownie batter?
Absolutely! Just make sure your batter is thick enough to hold the peanut butter cup and layer nicely in the muffin tin.
Can I make these gluten-free?
Yes—swap the all-purpose flour for your favorite gluten-free blend. Double-check that your peanut butter cups are also gluten-free.
How do I keep the peanut butter layer from sinking?
Layer the batter properly and avoid overfilling the cups; gently press the peanut butter cup in rather than sinking it down to the bottom.
