To make these bite size Reese's peanut butter cup brownies, you will need a mini muffin pan greased with butter or cooking spray.
Step by Step Instructions
Step 1: In the microwave or in a heat safe medium bowl over a double boiler on low heat, melt the chocolate and butter together until smooth. Remove from the heat and stir in the sugar for a few minutes, followed by the egg.
Step 2: Mix flour, cocoa powder, and salt together in a small bowl. Then fold the dry ingredients into the wet ingredients.
Step 3: Evenly distribute the brownie batter across the 24 greased muffin wells.
Step 4: Press miniature peanut butter cups into the brownies and bake at 325°F for 9-12 minutes until the edges are set. Cool in the mini muffin tin for 10-20 minutes, then transfer to a wire rack to cool completely.
Tip #1 - If you melt your butter and chocolate in the microwave, do it in 30 second bursts while stirring in between each, until fully melted. It should only take about 1 minute.
Tip #2 - Stir the sugar into the chocolate butter mixture while it's still warm. This will help the sugar dissolve and cool down the mixture before adding the egg.
Tip #3 - You can use a spoon or a cookie scoop to cleanly transfer the batter to the mini cupcake tin.
Tip #4 - Be sure to remove the brownies after they've cooled, but are still warm. If they're too hot, they will fall apart easily, and if they've cooled for too long, they will stick in the pan.
Yes absolutely! Follow steps 1 & 2 as written, then smooth the batter into a greased square baking pan, spacing the peanut butter cups evenly throughout. Bake and cool, then remove from the pan and cut into your desired brownie size.
Yes, these brownies freeze beautifully and are great straight out of the freezer or brought back to room temperature.
Room Temperature: Place in an airtight container and store at room temperature for up to 1 week.
Freezing Instructions: These brownie bites can be kept in a freezer-safe bag for up to 1 month.

Mini Peanut Butter Cup Brownies
- Mixing bowl

- Measuring spoons
- Small/medium cookie scoop
- 24-well Mini Muffin Pan
- ½ cup (1 stick) unsalted butter
- 1 cup semi-sweet chocolate chips or chocolate chunks
- ⅔ cup granulated sugar
- 2 large eggs room temperature
- ⅔ cup all-purpose flour
- ¼ cup cocoa powder
- ¼ teaspoon salt
- 24 miniature peanut butter cups
- Preheat oven to 325°F and grease a mini muffin pan with non-stick spray or fill with mini parchment liners.
- In a microwave-safe bowl, heat and stir the chocolate chips and butter in 30 second intervals until smooth.
- Whisk the sugar into the warm chocolate mixture until it's cool and homogenous (about 2 minutes). Stir in the eggs.
- Gently fold the flour, cocoa powder and salt into the wet ingredients using a spatula just until all flour streaks have disappeared.
- Using a small cookie scoop or spoon, fill each well of the prepared pan ~½ full with brownie batter. Then, press a mini peanut butter cup into each one.
- Bake for 9-12 minutes, or until the edges look slightly firm and dry.
- Let the brownies cool in the pan for about 10 minutes and then remove them. If your pan is greased well and slightly warm, you should be able to give them a little twist and pull them right out. Otherwise, you might need to carefully scoop them out with a knife.
