Step-by-step instructions
Here’s how to bring your Reeses Peanut Butter Oatmeal Cookies to life:
- Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper to prevent sticking.
- Cream Together: In a large bowl, cream together the peanut butter, softened butter, brown sugar, and granulated sugar until the mixture is smooth and fluffy.
- Add Egg & Vanilla: Beat in the egg and vanilla extract until everything is well combined.
- Separate Dry Ingredients: In another bowl, whisk together the flour, baking soda, and salt until well mixed.
- Combine Mixtures: Gradually add the dry mixture to the peanut butter mixture, stirring until just combined.
- Oats & Chocolate: Gently fold in the rolled oats and chopped Reese’s peanut butter cups until evenly distributed.
- Shape the Cookies: Scoop rounded tablespoons of dough onto the lined baking sheet, leaving about 2 inches between each cookie for spreading.
- Bake: Cook in the preheated oven for 10-12 minutes or until the edges are lightly golden.
- Cool Down: Let the cookies cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely.
How to plate and pair
These Reeses Peanut Butter Oatmeal Cookies can be enjoyed in numerous ways. For a delightful presentation, stack a few cookies on a plate and drizzle with melted chocolate or a sprinkle of sea salt. Pair them with a tall glass of milk, or serve alongside a scoop of your favorite vanilla ice cream for an indulgent dessert.
Keeping leftovers fresh
To preserve their chewiness and flavor, store your cookies in an airtight container at room temperature for up to one week. If you plan to enjoy them later, you can freeze the dough balls before baking. Just place them in a freezer-safe bag, and when you’re ready, bake directly from frozen, adding a minute or two to the baking time.
Helpful cooking tips
- Softened Butter: Make sure your unsalted butter is adequately softened. You can achieve this quickly by microwaving it for just a few seconds — but don’t melt it!
- Oat Quality: Using old-fashioned rolled oats rather than instant oats will give your cookies the best texture.
- Chop Evenly: When chopping the Reese’s peanut butter cups, try to have consistently sized pieces to ensure even distribution throughout the cookies.
Creative twists
Feeling adventurous? Try swapping the Reese’s for other candies like chopped Snickers for a different flavor profile, or add a touch of cinnamon to the dry ingredients for a warm, spiced flavor. For a healthier twist, use whole wheat flour and natural peanut butter for fewer processed ingredients while still retaining deliciousness.
