Dark Chocolate Peanut Butter Cup Cookies, Made Easy

Now that you have all your ingredients and equipment ready, let’s get started on making these Dark Chocolate Peanut Butter Cup Cookies!
Step 1: Preheat your oven
Preheat your oven to 350°F (175°C). This will ensure that your cookies bake evenly.
Step 2: Mix the dry ingredients
In a medium mixing bowl, whisk together the all-purpose flour, cocoa powder, baking soda, and salt. Set this mixture aside for later.
Step 3: Cream the butter and sugars
In a large mixing bowl, use an electric mixer to cream together the softened unsalted butter, granulated sugar, and light brown sugar until the mixture is light and fluffy.
Step 4: Add the eggs and vanilla
Beat in the eggs, one at a time, ensuring each is fully incorporated. Add the vanilla extract and mix until combined.
Step 5: Combine wet and dry ingredients
Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined. Be careful not to overmix!
Step 6: Add the milk
Pour in the milk and mix until the dough is smooth. The dough should be thick and slightly sticky.
Step 7: Fold in the goodies
Gently fold in the coarsely chopped peanut butter cups and bittersweet chocolate morsels using a spatula. This will give your cookies those delightful chocolate and peanut butter pockets.
Step 8: Scoop and bake
Using a cookie scoop, drop tablespoon-sized portions of dough onto baking sheets lined with parchment paper, leaving about 2 inches of space between each cookie. Bake for 10-12 minutes, or until the edges are set but the centers are still soft.
Step 9: Cool and enjoy
Once baked, remove the cookies from the oven and allow them to cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely. Enjoy your delicious Dark Chocolate Peanut Butter Cup Cookies with a glass of milk or your favorite beverage!
Substitutions by Category

If you’re looking to make a few substitutions or adapt the recipe, consider the following options:
- Flour: Whole wheat flour can be used for a healthier option, though it may change the texture slightly.
- Cocoa Powder: Dark cocoa powder can be substituted for a more intense chocolate flavor.
- Butter: Coconut oil or a vegan butter can be used for a dairy-free version.
- Sugar: Coconut sugar or maple syrup can be used for a less processed sweetener.
- Peanut Butter Cups: For a nut-free version, try using sunflower seed butter cups or chocolate-covered caramel candies.
Avoid These Mistakes
To ensure the best results with your Dark Chocolate Peanut Butter Cup Cookies, keep these tips in mind:
- Make sure your butter is softened but not melted. This is crucial for the right texture.
- Don’t skip the chilling step if you live in a warm climate; chilling the dough can prevent the cookies from spreading too much.
- Always measure your flour correctly. Too much flour can lead to dry cookies.
- Keep an eye on the baking time; overbaking can lead to hard cookies instead of chewy ones.
Shelf Life & Storage
If you find yourself with leftover cookies (though we doubt it!), here’s how to store them:
You can keep your Dark Chocolate Peanut Butter Cup Cookies in an airtight container at room temperature for up to a week. For longer storage, consider freezing them. Place the cookies in a single layer in a freezer-safe container, separating layers with parchment paper, and freeze for up to three months. When ready to enjoy, simply thaw at room temperature or pop them in the microwave for a few seconds to warm up!
Quick Questions

Absolutely! You can mix and match different types of chocolate, such as milk chocolate or white chocolate morsels, according to your preference.
How can I make these cookies gluten-free?
