Ingredients You’ll Need
- 1 cup (267g) peanut butter: Choose creamy or crunchy based on your preference. This is the star ingredient that provides rich flavor and texture.
- 1 large egg: Acts as a binder to help the ingredients hold together.
- 1 cup (200g) sugar: You can use all granulated sugar, all brown sugar, or a mix of both for different flavor profiles.
- 1 teaspoon baking soda: Optional for stability. Helps the cookies rise slightly for a fluffy texture.
- ½ cup (100g) Reese’s Pieces: Adds a colorful crunch and reinforces the peanut butter chocolate theme.
- 1 cup (136g) finely chopped Reese’s Peanut Butter Cups: For that gooey, melty center that makes these cookies an absolute delight.
How to Make Ultimate Reese’s Peanut Butter Cookies
- Preheat the Oven: Preheat your oven to 350°F (180°C). This ensures even baking. Line two cookie sheets with Silpats or parchment paper for easy cleanup.
- Mix the Cookie Dough: In a large bowl, combine 1 cup of peanut butter, 1 large egg, 1 cup of sugar, and 1 teaspoon of baking soda. You can use an electric mixer if you prefer, but mixing by hand is just as effective. Stir until everything is well-combined.
- Add the Goodies: Gently fold in ½ cup of Reese’s Pieces and 1 cup of finely chopped Reese’s Peanut Butter Cups. Make sure they are evenly distributed throughout the dough for a full flavor experience.
- Scoop the Dough: Using a 2 tablespoon cookie scoop, portion dough onto your prepared cookie sheets, leaving enough space between each.
- Flatten the Cookies: With the tines of a fork, gently press down on each cookie to flatten them slightly. This gives them that classic cookie shape and allows for even baking.
- Bake: Place the cookie trays in the oven and bake for about 8 minutes. Cookies will be soft and slightly golden around the edges. Keep an eye on them to avoid overbaking.
- Cool and Enjoy: Allow cookies to cool for about 15 minutes on the cookie sheet before transferring them to a wire rack. These cookies can be a bit crumbly, so handle them with care!
Storing & Reheating
Store your Ultimate Reese’s Peanut Butter Cookies at room temperature, in an airtight container, for up to a week. If you need more time, refrigerate them for 1-2 weeks in a sealed container. You can also freeze them for up to 3 months; just be sure to wrap them tightly in plastic wrap before placing them in a freezer-safe bag. When ready to enjoy, simply reheat in a microwave for about 15-20 seconds to refresh their soft and chewy texture.
