Essential Ingredients
To make these extra-soft Reese’s Peanut Butter Cookies, you’ll need:
- ½ cup butter, softened – Use unsalted butter for better control of the salt level. The softened texture helps create a creamy base.
- ½ cup creamy peanut butter – Choose regular peanut butter, not the natural kind that separates. The oils in regular peanut butter help keep the cookies soft.
- ¾ cup brown sugar – Brown sugar contains molasses which adds moisture and helps create that soft, chewy texture.
- ¼ cup white sugar – Provides structure and the perfect amount of sweetness.
- 1 large egg + 1 egg yolk – The extra yolk adds richness and helps keep the cookies soft.
- 2 teaspoons vanilla extract – For flavor depth.
- 1¾ cups all-purpose flour – The right amount for soft, not cakey cookies.
- ½ teaspoon baking soda – Helps the cookies rise slightly while baking.
- ½ teaspoon salt – Enhances all the flavors.
- 1½ cups chopped Reese’s Peanut Butter Cups – The star of the show!
Possible Substitutions:
- Peanut Butter: If you have allergies, try almond or sunflower seed butter.
- Brown Sugar: Can use all white sugar in a pinch, but the cookies won’t be as soft.
- Reese’s Cups: Try Reese’s Pieces, chocolate chips, or any candy with peanut butter.
- Gluten-Free Option: Substitute a 1:1 gluten-free flour blend.
Step-by-Step Instructions
Step 1: Prepare Your Ingredients
- Take the butter out of the fridge about 30 minutes before baking to soften.
- Unwrap and chop the Reese’s Peanut Butter Cups into small chunks.
- Preheat your oven to 350°F (175°C).
- Line cookie sheets with parchment paper.
Step 2: Mix the Wet Ingredients
- In a large mixing bowl, cream together the softened butter and peanut butter until the mixture is smooth and creamy.
- Add both brown and white sugars and beat until the mixture is light and fluffy (about 2-3 minutes).
- Add the egg, extra egg yolk, and vanilla. Mix until well combined.
Step 3: Add the Dry Ingredients
- In a separate bowl, whisk together the flour, baking soda, and salt.
- Slowly add the dry ingredients to the wet mixture, stirring just until combined.
- Be careful not to overmix – this can make your cookies tough instead of soft!
Step 4: Fold in the Reese’s
- Gently fold in most of the chopped Reese’s Peanut Butter Cups, saving some to press on top.
- The dough will be soft and a bit sticky – this is exactly what you want for soft cookies!
Step 5: Shape and Bake
- Scoop balls of dough (about 2 tablespoons each) onto your prepared cookie sheets.
- Press a few pieces of reserved Reese’s on top of each cookie.
- Bake for 9-10 minutes, until the edges are just set but the centers still look slightly underbaked.
- This is the secret to soft cookies – they’ll continue cooking on the hot cookie sheet!

Pro Tips for Extra Soft Cookies:
- Don’t overbake! Take them out when they still look slightly underdone in the center.
- Chill the dough for 30 minutes before baking if you want thicker cookies.
- Use room temperature eggs for better mixing.
- Measure flour correctly by spooning it into measuring cups and leveling off with a knife.
- Let them cool on the baking sheet for 5 minutes before moving to a cooling rack.
Assembly and Presentation
These cookies look best when they have visible pieces of Reese’s on top. Here’s how to make them look just as amazing as they taste:
- After scooping the dough, press a few extra chunks of Reese’s on top of each cookie.
- For a bakery-style look, sprinkle a tiny bit of flaky sea salt on top before baking.
- Let the cookies cool for 5 minutes on the baking sheet, then transfer to a wire rack.
- For perfect circles, use a round cookie cutter slightly larger than your cookie to gently “scoot” around each warm cookie.

Serving Suggestions:
- Stack 3-4 cookies and tie with a ribbon for a sweet gift.
- Serve warm with a cold glass of milk.
- Make mini ice cream sandwiches by placing a small scoop of vanilla ice cream between two cookies.
- Drizzle cooled cookies with melted chocolate for an extra fancy touch.

FAQ:
Why did my cookies come out hard instead of soft?
The most common reason is overbaking. Remember to take them out when they still look slightly underdone in the center. Also, make sure you’re using enough brown sugar and the extra egg yolk for moisture.
Can I use crunchy peanut butter instead of creamy?
Yes! Crunchy peanut butter will give you soft cookies with tiny bits of peanuts throughout. It’s a great option if you enjoy some texture in your cookies.
How do I know when the cookies are done?
The edges should be set and slightly golden, but the centers will look underbaked. They’ll continue cooking on the hot cookie sheet after you take them out of the oven.
Can I make these cookies without peanut butter cups?
Absolutely! You can substitute chocolate chips, candy pieces, or even leave them plain for a traditional peanut butter cookie.
Are these cookies freezer-friendly?
Yes! Both the baked cookies and the raw dough freeze beautifully. See our storage tips above for details.
Why add the extra egg yolk?
The extra egg yolk adds richness and helps keep the cookies soft and chewy longer.
Can I make bigger or smaller cookies?
Yes! Just adjust the baking time – smaller cookies need less time (about 7-8 minutes) and larger cookies need more (about 12-13 minutes).
How can I make these cookies healthier?
Try using natural peanut butter (though texture may change slightly), reduce the sugar by ¼ cup, or substitute part of the all-purpose flour with whole wheat flour.
Why did my Reese’s cups melt too much?
If you live in a warm climate, try freezing the chopped Reese’s cups for 30 minutes before adding them to the dough. This helps them hold their shape during baking.
Can I use this recipe to make cookie bars instead?
Yes! Press the dough into a greased 9×13 pan and bake for 20-25 minutes at 350°F. Let cool completely before cutting into squares.
