How to make these cookies?

Step 1:

Preheat your oven to 350°F and line a baking sheet with parchment paper.

Step 2:

In a large bowl, cream together the softened butter, light brown sugar, and granulated sugar until the mixture is light and fluffy, about 5 minutes.

Step 3:

Add the egg yolks and vanilla extract, blending until smooth.

Step 4:

Mix in the creamy peanut butter until fully combined.

Step 5:

In a separate bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt.

Step 6:

Gradually add the dry ingredients to the wet, stirring just until the dough forms.

Step 7:

Fold in ½ cup of chopped peanut butter cups gently.

Step 8:

(Optional) Swirl 1 tablespoon of peanut butter into the dough for extra richness.

Step 9:

Scoop about 2 tablespoons of dough onto your prepared baking sheet, spacing them about 2 inches apart. Top each cookie with extra peanut butter cups if you like.

Step 10:

Bake for 9 to 12 minutes, until the edges are golden but the centers still feel soft.

Step 11:

Let cookies cool on the baking sheet for a few minutes before transferring to a cooling rack. Serve warm or store in an airtight container.

Some Tips!

  • Use room temperature egg yolks to help the dough come together smoothly.
  • Don’t overmix once you add the flour; you want tender, not tough, cookies.
  • If you like extra peanut butter flavor, swirl peanut butter into the dough before baking.
  • Freeze leftover dough balls on a tray, then transfer to a bag for easy future baking sessions.
  • Baking time can vary slightly; check at 9 minutes and adjust for your oven for that perfect gooey center.

How to Store Leftovers?

Store leftover cookies in an airtight container at room temperature for up to 4 days. To keep them soft, add a slice of bread to the container. Alternatively, freeze baked cookies for up to 3 months in a freezer-safe bag.

What to Eat With?

These peanut butter cup cookies are a sweet treat on their own but pair amazingly with warm drinks like your favorite coffee or hot chocolate. For meals, they’d complement crowd-pleasers like Easy Shepard’s Pie or a comforting bowl of Pasta with Bacon and Peas, offering a sweet finish to a hearty dinner. If you’re in the mood for more dessert inspiration, try this Crumbl Sugar Cookie Copycat, or for something a bit more balanced, these Easy Chocolate Protein Pancakes make a great option.

FAQ

Can I use natural peanut butter instead of creamy peanut butter?

Natural peanut butter has more moisture and oil, which can affect cookie texture. For best results, use creamy, not natural peanut butter.

How do I make the cookies softer?

For softer cookies, take them out as soon as the edges turn golden and the centers still look slightly underbaked.

Can I make the dough ahead of time?

Yes! You can freeze the dough balls and bake them fresh later. Just add a couple of extra minutes to the baking time.

What if I don’t want to add extra peanut butter cups on top?

That’s fine — the chopped peanut butter cups inside the dough already provide plenty of chocolatey peanut butter goodness.

How should I store leftover cookie dough?

Wrap the dough tightly in plastic and freeze for up to 3 months. Thaw in the fridge overnight before baking.
