Gooey Peanut Butter Cookie Bites
Two Fridays ago, I was elbow-deep in flour with my friend Rita’s twins climbing on stools next to me, asking if they could “squish the cookies again.” It was our semi-regular “Snack & Story” afternoon, where I bake with the kids while their moms catch up over matcha lattes in the backyard. That day’s theme was “hidden treasures,” and I figured what better treat than little cookie bites filled with creamy peanut butter cores and melty chocolate?
Earlier that morning, I’d run into my neighbor Jacob at the grocery store, staring helplessly at the peanut butter shelf. He confessed he wanted to make something “small but sweet” for his sister’s birthday picnic. I walked him through the idea of making Peanut Butter Cookie Bites because they’re easy enough for beginners but feel like a bakery indulgence.
These mini wonders also made an appearance last December, tucked into a festive tin I mailed to my cousin in Portland, who said they “tasted like childhood.” It’s the kind of recipe that’s flexible enough for every age, every craving, and every occasion from a quiet tea moment to a big birthday bash and spark wide-eyed delight in anyone who takes a bite.

Short Description
Peanut Butter Cookie Bites are soft, golden mini cookies baked in muffin tins with a creamy peanut butter center and melted chocolate chips on top.
Key Ingredients

- 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 Filling
- 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
Tools Needed
- Muffin tin
- Paper muffin liners
- Hand mixer or stand mixer
- Mixing bowls
- Measuring cups and spoons
- Spatula
- Wire cooling rack
Cooking Instructions
Step 1: Prepare the Oven and Pan
Preheat your oven to 350°F (175°C). Line a standard muffin tin with paper liners for easy release and cleanup.
Step 2: Make the Cookie Dough
In a large bowl, cream the softened butter with brown and granulated sugar using a mixer for 2–3 minutes until fluffy. Beat in the egg (if using) and vanilla extract. Gradually mix in the flour until a soft dough forms. If the dough feels sticky, add a bit more flour, 1 tablespoon at a time.
Step 3: Prepare the Peanut Butter Filling
In a separate bowl, stir the peanut butter and powdered sugar until smooth. Roll into 24–30 small balls and refrigerate for 10 minutes to firm up.
Step 4: Assemble the Cookie Bites
Scoop dough into the muffin liners, pressing it into a shallow cup shape. Place one peanut butter ball into the center of each. Sprinkle with chocolate chips and optional candies or nuts. Lightly press a small piece of extra dough over the top to partially cover.
Step 5: Brush and Bake
Brush the tops with the egg yolk-water mixture for color. Bake for 12–15 minutes, or until edges are lightly golden and the tops look set.
Step 6: Cool and Serve
Let them rest in the pan for 5 minutes, then carefully transfer to a wire rack. The centers will be gooey when warm and set as they cool.

Mistakes to Avoid & Solutions
Using warm peanut butter balls
They’ll melt too quickly and leak into the dough.
Solution
Always chill the filling for at least 10 minutes before baking for a cleaner, gooier center.
Overfilling the muffin cups
Too much dough or filling can cause overflow or underbaking.
Solution
Stick to 1 heaping tablespoon of dough per cup, and don’t pack it too tightly.
Skipping the liners
Removing cookie bites from the tin can be messy without liners.
Solution
Use paper liners or generously grease the pan if going without.
Undermixing the butter and sugars
The texture may turn grainy and dense.
Solution
Beat until creamy and smooth, at least 2–3 minutes, before adding eggs or flour.
Overbaking
They’ll lose their soft, gooey center.
Solution
Remove from the oven when edges are golden but centers still look soft.

Storage and Reheating Tips
Store in an airtight container at room temperature for up to 4 days

Thaw frozen bites at room temperature before serving
Avoid refrigeration can dry out the texture
FAQs
1. Can I skip the egg in the dough?
Yes. The egg is optional and helps with binding, but the bites work well without it.
2. What kind of peanut butter should I use?
Use creamy peanut butter for best texture. Avoid natural peanut butter as it’s too oily.
3. Can I make these gluten-free?
Yes, just substitute with a 1:1 gluten-free flour blend designed for baking.
4. How do I prevent the tops from cracking?
Don’t press the top dough too tightly. Let it lightly cover the filling without sealing completely.
5. Can I double this recipe?
Absolutely! It scales beautifully and is great for batch baking during holidays.
Tips & Tricks
Chill the dough for 15 minutes if your kitchen is warm
Add a pinch of sea salt on top for contrast
Use a small cookie scoop for consistent portioning
Swap chocolate chips for dark or white chocolate
Let kids decorate the tops before baking for a colorful finish
Recipe Variations
1. Chocolate Lovers Version
Replace ½ cup of flour with unsweetened cocoa powder for a chocolate cookie base. The result is a rich, brownie-like texture with the same peanut butter core.
2. Jam-Filled Twist
Skip the peanut butter center and instead use ½ teaspoon of raspberry or strawberry jam. Pair with white chocolate chips for a fruity, creamy combo.
3. Nut-Free Alternative
Sub sunflower seed butter for peanut butter and omit any nut toppings to make the bites school-friendly.
4. S’mores Style
Add mini marshmallows and crushed graham crackers to the topping, and use chocolate chunks instead of chips.
5. Salted Caramel Core
Swap peanut butter filling with a thick caramel spread. Sprinkle with flaky salt before baking for a sophisticated sweet-salty bite.
Final Thoughts
The kitchen went still as the first tray of Peanut Butter Cookie Bites cooled tiny hands paused mid-reach, and even the adults leaned in for seconds. The smell of golden sugar, peanuts, and warm chocolate lingered in the air like a quiet celebration.
A short list of ingredients turns into something far more magical than expected. These bites bring joy to lunchboxes, surprise visits, or lazy afternoons that call for a soft, gooey treat baked with intention.
Bake a batch for someone you love, or share them just because it makes the day feel brighter. Peanut Butter Cookie Bites aren’t just dessert they’re the kind of little joy we could all use more often.
