On a rainy afternoon not long ago, the house felt unusually quiet. My husband had dozed off with the newspaper on his lap, and I could hear the soft drip of rain on the kitchen window. I decided that the best way to fill the silence was to bake something warm and comforting. Peanut butter has always been a family favorite, so I started pulling out the ingredients before I’d even fully decided what to make.
The idea of these cookie bites came from my granddaughter Emma, who once asked me if cookies could be shaped like “tiny muffins stuffed with peanut butter.” I remember her wide-eyed excitement when I told her we could give it a try. That memory inspired me to bake these again, even though Emma wasn’t there that day.
As I worked the butter and sugar together, the smell alone lifted my mood. The rhythm of measuring, stirring, and shaping the dough became a little escape from the gloomy weather outside. By the time the oven timer beeped, the entire house was filled with the warm, nutty aroma that always reminds me of family gatherings.
These cookie bites have a way of bringing everyone into the kitchen. They’re soft on the outside, gooey in the center, and always gone within minutes. Sometimes the simplest recipes become the most treasured because they carry stories, not just flavors.

Key Ingredients
Dough Base
- 1 cup unsalted butter, softened
- ¾ cup brown sugar
- ½ cup granulated sugar
- 1 large egg (optional)
- 1 teaspoon vanilla extract
- 2 cups all-purpose flour
Peanut Butter Layer
- ½ cup creamy peanut butter
- ¼ cup powdered sugar
Mix-ins & Toppings
- 1½ cups semi-sweet chocolate chips
- ¼ cup crushed Reese’s Pieces, chopped peanuts, or mini M&Ms (optional)
For Finishing
-
1 egg yolk mixed with 1 tablespoon water for brushing
Tools Needed
- Standard 12-cup muffin tin
- Paper liners
- Electric mixer or sturdy whisk
- Mixing bowls (one large, one medium)
- Measuring cups and spoons
- Cooling rack
Cooking Instructions
Step 1: Prepare the Oven and Pan
Preheat oven to 350°F (175°C). Line a muffin tin with paper liners to keep the bites from sticking and for easy cleanup.
Step 2: Make the Cookie Dough
In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until the mixture is light and fluffy, about 2–3 minutes with a mixer. Beat in the egg (if using) and vanilla extract until smooth. Gradually mix in the flour until a soft dough forms. If the dough feels sticky, add 1 tablespoon of flour at a time.
Step 3: Prepare the Peanut Butter Filling
In a separate bowl, stir the peanut butter with powdered sugar until smooth. Shape the mixture into 24–30 small balls and refrigerate for about 10 minutes to firm them up.
Step 4: Assemble the Cookie Bites
Press a portion of cookie dough into each muffin cup, shaping a shallow well in the center. Place a chilled peanut butter ball into each well. Add a sprinkle of chocolate chips and optional crushed candies or nuts on top. Cover lightly with a small piece of the remaining dough to partially enclose the filling.
Step 5: Brush and Bake
Brush the tops with the egg yolk and water mixture for a lovely golden color. Bake for 12–15 minutes until the edges are lightly golden and the tops feel set.
Step 6: Cool and Serve
Let the cookie bites rest in the muffin tin for 5 minutes before transferring them to a wire rack. The centers will be gooey at first but firm as they cool.
Why You’ll Love This Recipe

Mistakes to Avoid & Solutions
Overmixing the Dough: Can make cookies tough. Mix just until ingredients come together.
Skipping the Chill Step: Unchilled peanut butter balls may melt too quickly, so chilling keeps the filling intact.
Overbaking: Leads to dry cookie bites. Remove when edges are just golden; they’ll finish setting as they cool.
Not Using Liners: The bites can stick to the pan, so liners save both the treats and your cleanup time.
Too Much Filling: Avoid overstuffing to prevent overflow while baking.
Serving and Pairing Suggestions
Serve slightly warm for the gooey center effect.
Pair with a cold glass of milk or a hot cup of coffee for a cozy afternoon snack.
Arrange on a dessert platter with fresh berries and mini brownies for parties.
Drizzle with melted chocolate or caramel for an extra decadent touch.
Storage and Reheating Tips
Store cooled cookie bites in an airtight container at room temperature for up to 3 days.
For longer storage, refrigerate for up to 1 week.
To freeze, wrap individually and keep in a freezer-safe bag for up to 2 months.
Reheat in a microwave for 10–15 seconds or in a 300°F oven for 3–4 minutes to restore softness.
FAQs
1. Can I use natural peanut butter?
Yes, but it should be well-stirred and not too runny; otherwise, add an extra tablespoon of powdered sugar for firmness.
2. Do I have to use the egg in the dough?
No, the egg helps with structure but can be omitted for a slightly denser cookie.
3. How do I prevent the dough from sticking to my fingers?
Lightly flour your hands or chill the dough for 10 minutes before shaping.
4. Can I make these ahead for a party?
Absolutely. Prepare and bake them the day before, then store in an airtight container.
5. What if I don’t have paper liners?
Grease the muffin tin generously with butter or cooking spray, but liners make removal much easier.
Tips & Tricks
For a richer flavor, brown half of the butter before creaming with the sugars.
Use a small cookie scoop for evenly sized dough portions.
Sprinkle sea salt on top before baking for a sweet-salty contrast.
Add a teaspoon of espresso powder to the dough to deepen the chocolate notes.
Allow the bites to cool at least 10 minutes before removing them from the liners to keep them intact.
Recipe Variations
Chocolate Swirl Peanut Butter Bites: Swirl 2 tablespoons of melted chocolate into the peanut butter filling before chilling.
Nutty Crunch Version: Fold ½ cup of chopped roasted peanuts into the cookie dough for extra texture.
Holiday Sprinkle Bites: Swap chocolate chips with red and green candy-coated chocolates for a festive touch.
Caramel Drizzle Bites: After baking, drizzle warm caramel over the cooled cookie bites for a richer dessert.
Gluten-Free Option: Use a 1:1 gluten-free all-purpose flour blend in place of regular flour.
