Ingredients You’ll Need
- 1 cup (267g) peanut butter: This is the star ingredient that lends that signature flavor. Creamy is best, but crunchy will add texture!
- 1 large egg: Acts as a binder, helping the cookies hold their shape.
- 1 cup (200g) sugar: Feel free to use all granulated, all brown, or a mix for a richer flavor.
- 1 teaspoon baking soda (optional): This helps to give the cookies a bit more lift for a sturdier cookie.
- ½ cup (100g) Reese’s Pieces: Adds a fun crunch and bursts of peanut butter flavor.
- 1 cup (136g) finely chopped Reese’s peanut butter cups: These mini candies are the ultimate indulgence that makes each cookie unforgettable.
How to Make Ultimate Reese’s Peanut Butter Cookies
- Preheat the Oven: Set your oven to 350°F. Line two cookie sheets with Silpats or parchment paper to prevent sticking.
- Mix the Dough: In a large bowl, combine 1 cup peanut butter, 1 large egg, 1 cup sugar, and 1 teaspoon baking soda. You can use a mixer for a smooth consistency, but it’s just as easy to mix it by hand.
- Fold in the Goodies: Once combined smoothly, gently stir in ½ cup Reese’s Pieces and 1 cup finely chopped Reese’s peanut butter cups for that perfect chocolatey surprise in each bite.
- Shape Cookies: Scoop tablespoons of cookie dough onto the prepared sheets, spacing them about 2 inches apart. A 2-tablespoon cookie scoop is perfect for this. Use a fork to flatten each cookie slightly, creating the classic crisscross pattern.
- Bake to Perfection: Bake in your preheated oven for about 8 minutes. Keep an eye out, as cookies are done when the edges are golden but the centers are still soft. Allow them to cool for 15 minutes on the cookie sheets before transferring to a wire rack.
Storing & Reheating
To store your cookies, simply place them in an airtight container at room temperature, where they’ll keep fresh for about 5 days. For longer storage, refrigerate them in a tightly sealed container for up to a week. If you want to keep them for even longer, freeze the cookies in a single layer on a baking sheet, then transfer them to a freezer-safe container. They can last up to 3 months! To warm them up, just pop them in the microwave for about 10-15 seconds for a chewy, warm treat.
Chef’s Helpful Tips
- Watch the baking time closely; these cookies can go from perfect to overbaked quickly!
- If you prefer your cookies even chewier, take them out when they look slightly underbaked in the center.
- You can mix different kinds of peanut butter or flavored nut butters for a twist.
- Make sure to use fresh Reese’s candy for the best flavor and texture.
- Feel free to add in other mix-ins like chopped nuts or a sprinkle of sea salt on top before baking for extra flavor.
These Ultimate Reese’s Peanut Butter Cookies are not just a treat; they’re a memory-maker, ideal for sharing with friends and family or savoring solo. The combination of flavors is hard to beat, and they bring smiles with every bite.

Recipe FAQs
Can I use natural peanut butter for this recipe?
Yes, you can use natural peanut butter, but be aware that cookies made with natural peanut butter may spread less and could be denser. Just ensure to stir the natural variety well before measuring.
What’s the best way to chop up the Reese’s peanut butter cups?
To chop Reese’s peanut butter cups efficiently, freeze them for about 15 minutes before cutting. This helps stabilize the chocolate and makes it much easier to cut cleanly.
How do I prevent my cookies from being too crumbly?
If your cookies are crumbly, try adding a little more peanut butter or an extra egg. This will give them more moisture and structure.
Can I freeze the cookie dough for later?
Absolutely! You can scoop out the dough into balls and freeze them. When you’re ready to bake, just add a minute or two more to the baking time from frozen. Enjoy the delicious aroma filling your kitchen!
