Ingredients List

- 1 cup brown sugar (packed tightly)
- 1/2 cup granulated sugar
- 2 large eggs (room temperature)

- 1 cup all-purpose flour (sifted)

- 1/2 teaspoon salt

How to Prepare Reese’s Pieces Peanut Butter Brownie Cookies
Step-by-Step Instructions
Alright, let’s get baking these delightful Reese’s Pieces Peanut Butter Brownie Cookies! First things first, preheat your oven to 350°F (175°C). You want it nice and hot so those cookies bake perfectly!
Next, grab a large mixing bowl and combine the creamy peanut butter, brown sugar, and granulated sugar. Use a sturdy spatula or a hand mixer to blend these together until the mixture is smooth and creamy. This step is super important because it ensures all those lovely flavors meld together. Don’t rush it! You want it to look like a beautiful, thick batter.
Once that’s done, crack in your two large eggs and pour in the vanilla extract. Mix again until everything’s well combined. The batter should now be silky and fragrant! Now, in a separate bowl, whisk together the sifted all-purpose flour, baking soda, and salt. This helps distribute the baking soda evenly throughout the flour, ensuring your cookies rise beautifully.
Now, it’s time to bring it all together! Gradually add the dry flour mixture to your wet ingredients, stirring gently. Avoid overmixing—just mix until you see no more flour streaks. Fold in those colorful Reese’s Pieces, making sure they’re evenly distributed throughout the dough. You can even save a handful to sprinkle on top of the cookies before baking for that extra pop of color!
With your dough ready, drop tablespoon-sized portions onto a baking sheet lined with parchment paper, spacing them about two inches apart. This gives them room to spread without sticking together. Bake in your preheated oven for 10-12 minutes, or until the edges are golden brown. Keep an eye on them; you want them soft in the center but set at the edges.
Once they’re out of the oven, let the cookies cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely. Trust me, the aroma wafting through your kitchen will be heavenly! Enjoy your cookies once they’re cooled, or store them away for later—if you can resist snacking on them right away!

Tips for Success
To ensure your Reese’s Pieces Peanut Butter Brownie Cookies turn out perfectly every time, here are some tried-and-true tips! First off, always use high-quality peanut butter. I love the creaminess of natural peanut butter, but make sure it’s well-stirred to avoid any oily separation. Trust me, the flavor is unbeatable!
When measuring your brown sugar, pack it tightly into the cup for the right sweetness and moisture. For that perfect chewy texture, be careful not to overbake. Cookies can look soft in the middle, but they’ll firm up as they cool, so take them out when the edges are golden and the centers still look a bit underbaked.
Lastly, let them cool on the baking sheet for a few minutes before transferring to a wire rack. This helps maintain their shape and ensures they’re soft and delicious. Happy baking!

FAQs About Reese’s Pieces Peanut Butter Brownie Cookies
Can I use natural peanut butter?
Absolutely! You can use natural peanut butter, but just keep a couple of things in mind. Make sure to stir it well before measuring since natural varieties can separate. The key is to avoid ones that are too runny, as they might change the texture of your cookies. I personally love the flavor of natural peanut butter, and it brings a delightful richness to the cookies!
How do I store the cookies?
To keep your delicious Reese’s Pieces Peanut Butter Brownie Cookies fresh, store them in an airtight container at room temperature. They’ll stay soft and chewy for about a week. If you want to keep them even longer, you could also put them in the fridge. Just remember to let them come to room temperature before enjoying, so they regain that lovely softness!
Can I freeze these cookies?
You bet! Freezing these cookies is super easy and a great way to have a sweet treat ready when you need it. Just let the cookies cool completely, then place them in a single layer on a baking sheet and freeze until solid. After that, transfer them into a freezer-safe bag or container, separating layers with parchment paper. They’ll stay good for up to three months. When you’re ready to enjoy, just let them thaw at room temperature, or pop them in the microwave for a few seconds for that fresh-baked warmth!
Storage & Reheating Instructions
To keep your Reese’s Pieces Peanut Butter Brownie Cookies at their best, storing them properly is key! Place any leftover cookies in an airtight container and keep them at room temperature. This way, they’ll stay soft and delicious for up to a week. If you want to keep them even longer, you can pop them in the fridge; just make sure to let them come back to room temperature before enjoying again.
If you find yourself with a stash of frozen cookies, reheating them is a breeze! Simply take the cookies out of the freezer and let them thaw at room temperature for about 15-20 minutes. If you’re in a hurry, you can warm them up in the microwave for about 10-15 seconds. This little trick makes them taste like they just came out of the oven—soft, warm, and oh-so-delicious!
