Ingredients for Reese’s Pieces Peanut Butter Brownie Cookies

Here’s what you’ll need to whip up these decadent cookies:

• 1 box brownie mix (choose your favorite; I used double fudge)
• 2 large eggs – Helps bind the dough together.
• ½ cup peanut butter – Creamy or crunchy, your choice!
• ¼ cup Nutella – Adds an extra layer of richness.
• ¼ cup all-purpose flour – Helps thicken the brownie batter into cookie dough.
• ½ cup melted butter – Makes the cookies extra soft and chewy.
• ¾ cup Reese’s Pieces – For that classic peanut butter crunch.

Variations for Reese’s Pieces Peanut Butter Brownie Cookies

• Make it extra gooey – Swirl extra peanut butter into the cookie dough before baking.
• Add chocolate chips – Mix in semisweet or milk chocolate chips for even more indulgence.
• Use white chocolate – Swap Nutella for white chocolate spread for a different flavor twist.
• Make them gluten-free – Use a gluten-free brownie mix and substitute flour with a gluten-free alternative.

Step-by-Step Instructions

1. Prepare the Dough

In a large mixing bowl, whisk together the brownie mix and flour. This helps turn the brownie batter into a thicker cookie dough consistency.

2. Mix Wet Ingredients

In a separate bowl, beat the eggs, melted butter, peanut butter, and Nutella until smooth. This combination gives the cookies their rich, fudgy texture.

3. Combine Wet and Dry Mixtures

Slowly add the wet mixture to the dry ingredients, stirring until fully combined. The dough will be thick and sticky—that’s exactly what you want!

4. Fold in Reese’s Pieces

Using a spatula, gently fold in the Reese’s Pieces. Be careful not to overmix—just enough to distribute them evenly throughout the dough. This ensures every cookie has that perfect peanut butter crunch.

5. Chill the Dough

Cover the bowl with plastic wrap and refrigerate the dough for at least 30 minutes. Chilling helps the flavors meld together and prevents the cookies from spreading too much while baking.

6. Preheat the Oven

Set your oven to 350°F (175°C) and line two baking sheets with parchment paper. This step ensures the cookies bake evenly and don’t stick to the pan.

7. Scoop and Shape

Use a cookie scoop or a spoon to portion out the dough into 1.5 to 2 tablespoon-sized balls. Place them about 2 inches apart on the baking sheet, as they will spread slightly while baking.

8. Add Extra Reese’s Pieces (Optional)

For a picture-perfect cookie, press a few extra Reese’s Pieces on top of each dough ball before baking. This makes the cookies look bakery-style and adds an extra pop of peanut butter flavor.

Baking and Cooling

9. Bake the Cookies

Place the baking sheets in the preheated oven and bake for 10-12 minutes. The cookies will appear slightly underbaked in the center, but don’t worry—they’ll continue to set as they cool.

10. Let Them Cool

Remove the cookies from the oven and let them cool on the baking sheet for 5 minutes. Then, transfer them to a wire rack to cool completely. This helps them firm up while keeping their soft, fudgy texture.

How to Serve Reese’s Pieces Peanut Butter Brownie Cookies

Reese’s Pieces Peanut Butter Brownie Cookies FAQs

Can I use a different brownie mix?

Yes! Any brownie mix will work. If using a mix that requires more liquid ingredients, slightly reduce the butter to balance the dough.

Can I make these cookies without Nutella?

Absolutely! If you prefer, leave out the Nutella or replace it with an equal amount of peanut butter for an extra nutty flavor.

Why do I need to chill the dough?

Chilling helps prevent the cookies from spreading too much and enhances the flavors. If you’re short on time, even 15 minutes in the fridge helps!

Can I make these cookies ahead of time?

Yes! The dough can be made up to 48 hours in advance and stored in the fridge. Just let it sit at room temperature for a few minutes before scooping and baking.

How do I make these extra gooey?

For an ultra-gooey center, slightly underbake the cookies (around 9 minutes) and let them set on the baking sheet before transferring them to a rack.
