Ingredients You’ll Need
- 1 cup (267g) peanut butter: Use creamy or crunchy peanut butter for a tasty base. Choose natural peanut butter for a less sugary version or stick to classic for that perfect texture.
- 1 large egg: This helps bind the cookies together, ensuring a chewy center. Make sure it’s at room temperature for better mixing.
- 1 cup (200g) sugar: You can use all granulated, all brown, or a combination for depth of flavor. The brown sugar will add moisture and a slight caramel flavor.
- 1 teaspoon baking soda: This optional ingredient provides stability and can help the cookies rise slightly for a lighter texture, although they remain dense.
- ½ cup (100g) Reese’s Pieces: These colorful candies add crunch and a pop of flavor. Use regular or mini ones, whichever you prefer!
- 1 cup (136g) finely chopped Reese’s peanut butter cups: This is where the magic happens! The delightful bites of chocolate and peanut butter in each cookie create incredible flavor bursts.
How to Make Ultimate Reese’s Peanut Butter Cookies
- Preheat your oven: Start by preheating your oven to 350°F. Line two cookie sheets with Silpats or parchment paper to prevent sticking and ensure easy cleanup.
- Mix your ingredients: In a large bowl, combine 1 cup of peanut butter, 1 large egg, 1 cup of sugar, and, if desired, the 1 teaspoon of baking soda. You can use a mixer for this step, but it’s just as easy to mix by hand until everything is well incorporated.
- Add the fun stuff: Stir in ½ cup of Reese’s Pieces and 1 cup of finely chopped Reese’s peanut butter cups. The dough will be thick and a bit sticky. Don’t be afraid to get your hands in there!
- Scoop out the dough: Use a 2-tablespoon cookie scoop to portion out the cookie dough onto your prepared cookie sheets. Space them about 2 inches apart so they have room to spread slightly.
- Flatten the cookies: Gently flatten each cookie ball using the tines of a fork. This step ensures even baking and gives a classic look to your cookies.
- Bake: Place the cookie sheets in the oven and bake for about 8 minutes. You want them to look set but a tad soft in the center. They’ll firm up as they cool.
- Cool down: Allow the cookies to cool on the sheets for about 15 minutes before carefully transferring them to a wire rack. Be cautious; they can be crumbly!
Storing & Reheating
To keep your cookies fresh, store them in an airtight container at room temperature for up to 5 days. If you want to save some for later, you can refrigerate them for a week or freeze them for up to 3 months. To reheat, simply pop them in a preheated oven at 350°F for a few minutes until warm. Keep in mind that their texture may soften slightly over time, so a quick reheat can help revive their original deliciousness.
Chef’s Helpful Tips
- Watch the cooking time: For perfectly soft cookies, err on the side of slightly underbaking. They’ll continue to bake a bit after being removed from the oven.
- Ingredient temperature: Make sure your eggs are at room temperature; this will help them incorporate better into the dough.
- Don’t skip the fork flattening: This not only helps them bake evenly but also creates a lovely texture on top.
- Satisfy your sweet tooth: Experiment with other mix-ins like chopped nuts or additional chocolate chips for various flavors.
- Use measuring cups: For the best results, measure peanut butter using a dry measuring cup for accuracy.
These Ultimate Reese’s Peanut Butter Cookies are not only easy to make but also incredibly satisfying. From their rich, peanut buttery flavor to the delightful crunch of chocolatey pieces, each cookie is a little piece of happiness. Don’t be afraid to tweak the recipe to suit your taste—add more Reese’s Pieces for extra crunch or try a sprinkle of sea salt on top before baking for a gourmet touch.
