Peanut Butter Fudge Cookie Cups are soft, chewy peanut butter cookies baked in a mini muffin tin and filled with a rich, two-ingredient chocolate fudge center. Nostalgic, bite-sized, and bakery-worthy, these treats combine salty peanut butter with smooth chocolate for the ultimate crowd-pleasing dessert.

Ingredients

**Peanut Butter Cookie Cups**

Unsalted butter, room temperature – ½ cup

Creamy peanut butter (no-stir) – ½ cup

Granulated sugar – ½ cup

Light brown sugar – ½ cup

Large egg, room temperature – 1

All-purpose flour – 1 ¼ cups

Baking soda – ½ teaspoon

Salt – ¼ teaspoon

**Chocolate Fudge Filling**

Semi-sweet chocolate chips – 1 cup

Sweetened condensed milk – ½ cup

Instructions

**Prep the Pan**

Preheat oven to 350°F (175°C). Lightly grease a 36-count mini muffin tin.

 

**Cream Butter and Sugars**

Beat butter, peanut butter, granulated sugar, and brown sugar until light and fluffy, about 2–3 minutes.

 

**Add Egg**

Mix in the egg until fully incorporated, scraping down the bowl as needed.

 

**Add Dry Ingredients**

Mix in flour, baking soda, and salt on low speed just until combined.

 

**Bake Cookie Cups**

Scoop about 1 tablespoon of dough into each muffin cup. Bake for 12–14 minutes until puffed and set.

 

**Form the Cups**

Immediately press a well into the center of each cookie using the back of a tablespoon or small scoop.

 

**Cool Slightly**

Let cookies cool in the pan for 10–15 minutes to set.

 

**Make the Fudge**

Heat chocolate chips and sweetened condensed milk together over low heat (or microwave in 20-second bursts), stirring until smooth and glossy.

 

**Fill and Set**

Spoon or pipe warm fudge into each cookie cup. Let set at room temperature or refrigerate for 30 minutes before serving.

Notes

• Use no-stir peanut butter for best structure—natural varieties may cause oily cookies.

• Do not overbake; cookies should look slightly underdone in the center.

• If cookies crumble, they need more cooling time before removal.

• Pipe the fudge for the cleanest, bakery-style finish.

• Cookie cups freeze well for up to 3 months.
