Ingredients You’ll Need
- 1 cup (267g) peanut butter: Use creamy or crunchy, depending on your texture preference; natural peanut butter will yield a softer cookie.
- 1 large egg: This binds the ingredients together for a chewy, moist cookie.
- 1 cup (200g) sugar: You can choose all granulated, all brown, or a mix for added flavor depth and moisture.
- 1 teaspoon baking soda (optional): A little baking soda helps provide a slightly puffed texture.
- ½ cup (100g) Reese’s Pieces: These colorful candies bring a fun crunch and playful touch to your cookies.
- 1 cup (136g) finely chopped Reese’s Peanut Butter Cups: The chopped cups infuse every bite with delicious chocolate-peanut butter flavor.
How to Make Ultimate Reese’s Peanut Butter Cookies
- Preheat the Oven: Start by preheating your oven to 350°F (175°C). Line two cookie sheets with Silpats or parchment paper to ensure a non-stick surface.
- Mix Ingredients: In a large mixing bowl, combine 1 cup of peanut butter, 1 large egg, 1 cup of sugar, and if you choose to include it, 1 teaspoon of baking soda. You can use a mixer for this step, but mixing by hand works beautifully too. Stir until everything is well combined.
- Add Candies: Gently fold in ½ cup of Reese’s Pieces and 1 cup of finely chopped Reese’s Peanut Butter Cups. The batter will be thick and slightly sticky, filled with bursts of chocolate and peanut butter goodness.
- Scoop the Dough: Using a 2-tablespoon cookie scoop, scoop out portions of dough onto your prepared cookie sheets, leaving space between each to allow for spreading.
- Flatten: Use the tines of a fork to gently press down each cookie dough ball, creating a crisscross pattern for an adorably classic cookie look.
- Bake: Place them in the oven and bake for 8 minutes. You’ll know they’re ready when the edges look golden but the centers still seem soft.
- Cool: Let them cool on the cookie sheets for 15 minutes before transferring them to a wire rack. Be gentle, as these cookies can be a bit crumbly!
Storing & Reheating
To keep your Ultimate Reese’s Peanut Butter Cookies fresh, store them in an airtight container at room temperature for up to a week. If you want to keep them longer, consider refrigerating them for up to two weeks. For longer storage, freeze the cookies in a single layer, then transfer them to a freezer-safe container for up to three months. When you’re ready to enjoy, simply pop them in the microwave for about 10 seconds to refresh their texture—just be mindful that thawed cookies might be a tad more crumbly than fresh-baked ones.
Chef’s Helpful Tips
- Avoid overbaking! Keep a close eye on your cookies; they may look under-baked but will continue to firm up as they cool.
- If you’re using natural peanut butter, give the jar a good stir before measuring out the cup to achieve an even consistency.
- Feeling adventurous? Add a sprinkle of sea salt on top before baking for an extra flavor boost!
- For a variation, swap out the Reese’s Pieces for your favorite chocolate chips or nuts.
- If your dough seems too dry, a splash of milk can help smooth it out without compromising flavor.
Sometimes, it’s the simplest recipes that become the most beloved, and those Ultimate Reese’s Peanut Butter Cookies fit right into that category. Not only do they satisfy those late-night sweet cravings, but they also make the perfect addition to lunchboxes or afternoon teas.

Recipe FAQs
Can I use natural peanut butter for this recipe?
Absolutely! Natural peanut butter adds a richer flavor, but keep in mind it might make your cookies slightly softer. Just make sure to stir the jar well before measuring for the best results.
How can I make my cookies chewier?
For chewier cookies, consider using brown sugar instead of granulated sugar or adding an extra egg yolk. Brown sugar has more moisture, which helps create that delightful chewy texture!
Can I freeze the cookie dough?
Yes, you can freeze the cookie dough! Just scoop the dough onto a parchment-lined baking sheet and freeze until solid. Once frozen, transfer them to a freezer-safe bag. You can bake them directly from the freezer; just add a couple of extra minutes to the baking time.
Why are my cookies crumbly?
If your cookies turn out crumbly, it might be due to overbaking or not enough binding ingredients. Make sure you’re measuring your ingredients accurately and keeping an eye on them in the oven. A bit of extra egg or even a tablespoon of milk can help in future batches.
