Peanut Butter Fudge Puddles Ingredients
Here's everything for the Peanut Butter Fudge Puddles and the creamy chocolate filling.
See Recipe Card Below This Post For Ingredient Quantities
For the Cookie Cups:
- Unsalted butter: Softened butter creates a tender, rich cookie base that's soft and chewy. Make sure it's at room temperature so it creams properly with the sugars.
- Brown sugar: Adds moisture and a hint of caramel flavor that pairs beautifully with peanut butter.
- Granulated sugar: Balances the brown sugar and helps the cookies hold their shape while baking.
- Egg: Binds everything together and adds structure to the dough.
- Creamy peanut butter: The star ingredient. Use a standard creamy peanut butter like Jif or Skippy, not natural or no-stir varieties, which can make the texture too oily.
- Vanilla extract: Enhances all the flavors and adds warmth to the cookie base.
- All-purpose flour: Gives the cookies structure. Spoon and level your flour to avoid dense cookies.
- Baking soda: Helps the cookies rise slightly and stay tender.
- Salt: Balances the sweetness and makes the peanut butter flavor pop.
For the Fudge Filling:
- Semi-sweet chocolate: Chopped chocolate melts more smoothly than chips. You can also use dark chocolate if you prefer a less sweet filling.
- Vegetable oil or coconut oil: Just a teaspoon helps the chocolate stay smooth and shiny when it sets.
- Mascarpone cheese: This is the secret ingredient. Room-temperature mascarpone blends into the chocolate and creates an ultra-creamy, melt-in-your-mouth fudge filling that stays soft even when chilled.
Optional Topping:
- Heath toffee bits or chopped peanuts: Adds a little crunch and makes them look bakery-pretty.
How to Make Peanut Butter Fudge Puddles
Making these Peanut Butter Fudge Puddles is easier than you'd think. The dough chills, the cookies bake, and the filling comes together in minutes.
Cream the butter and sugars: In a large bowl using a hand mixer or stand mixer fitted with a paddle attachment, beat the softened butter, brown sugar, and granulated sugar on medium-high speed until light and creamy, about 3 minutes. The mixture should look pale and fluffy.
Add the egg and peanut butter: Beat in the egg until combined, about 1 minute, scraping down the sides and bottom of the bowl as needed. Add the peanut butter and vanilla extract and beat until smooth and well mixed.
Mix in the dry ingredients: Add the flour, baking soda, and salt. Beat on low speed until incorporated, then increase to medium speed and beat until well combined. The dough will be very creamy and soft, almost like thick frosting.

Chill the dough: Cover the bowl and refrigerate for at least 1 hour, and up to 3 days. Chilling helps the dough firm up so it holds its cup shape when baked.
Preheat and prep: Preheat your oven to 325°F (163°C). Grease 2 mini muffin pans generously with nonstick spray, or bake in batches if you only have 1 pan.
Shape the cookie cups: Scoop and roll about 1 tablespoon of dough per ball and place each one in a muffin cup. Press your thumb gently into the center of each ball to create an indent, pressing the dough partway up the sides to form a little cup shape.
Bake: Bake for 14 to 15 minutes or until the edges are lightly browned. Don't under-bake or the cups won't hold their shape well.
Press the centers again: Remove from the oven and let cool in the pan for 5 to 10 minutes. The centers will puff up a bit, so use the back of a rounded teaspoon to gently press them down again while they're still warm.
Cool completely: Carefully remove the cookie cups from the pan and transfer them to a cooling rack to cool all the way before filling.
Melt the chocolate: Melt the chopped chocolate and oil together in a double boiler or in the microwave in 20-second increments, stirring between each, until smooth. Let it cool slightly for about 3 minutes so it doesn't melt the mascarpone.

Fold in the mascarpone: Gently fold the room-temperature mascarpone into the melted chocolate until combined. The filling will be thick, silky, and glossy.
Fill the cups: Spoon a heaping teaspoon of the mascarpone chocolate filling into each cooled cookie cup. The fudge should pool right in the center.
Add toppings: Sprinkle with toffee bits or chopped peanuts if you like a little crunch and extra flair.
Substitutions and Variations
You can make a few swaps based on what you have on hand.
No mascarpone? You can use softened cream cheese instead, though the filling will be slightly tangier and a bit firmer. Mascarpone gives you that true creamy fudge texture.
Different chocolate: Try milk chocolate for a sweeter filling or dark chocolate for something more sophisticated. White chocolate also works if you want a completely different flavor profile.
Nut-free version: Swap the peanut butter for sunflower seed butter or another nut-free spread. The texture will be similar, though the flavor will change.
Add espresso powder: A pinch of espresso powder in the fudge filling deepens the chocolate flavor without making it taste like coffee.
Make them bigger: You can bake these in a regular muffin pan for larger cookie cups. Increase the baking time to 16 to 18 minutes and use more dough per cup.
Equipment For Peanut Butter Fudge Puddles
Here's what makes the process smooth and easy.
- Mini muffin pan: Essential for getting those perfect little cup shapes. If you only have one pan, you can bake in batches.
- Hand mixer or stand mixer: Creaming the butter and sugar properly makes a big difference in texture.
- Rounded teaspoon: Perfect for pressing down the centers after baking without breaking the cookies.
- Microwave-safe bowl or double boiler: For melting the chocolate smoothly without scorching.
Storage Tips For Peanut Butter Fudge Puddles
Keep these Peanut Butter Fudge Puddles fresh and delicious for days.
Room temperature: Cover and store at room temperature for up to 1 day. The filling stays soft and creamy.
Refrigerator: Store in an airtight container in the fridge for up to 5 days. The fudge filling will firm up slightly when cold but still tastes amazing. Let them sit at room temperature for about 10 minutes before serving if you prefer a softer filling.
Freezing: You can freeze the baked and filled Peanut Butter Fudge Puddles for up to 2 months. Thaw in the fridge overnight before serving.
Serving Suggestions
These Peanut Butter Fudge Puddles dessert bites are versatile and always a hit.
Serve them on a cookie tray alongside Spumoni Cookies and Chocolate Chip Cookie Cake for a colorful dessert spread. They're perfect with a cold glass of milk or a cup of coffee for an afternoon treat.
For parties, arrange them on a platter with fresh berries and a dusting of powdered sugar for a bakery-style presentation. Kids love them in lunchboxes as a special surprise, and they're small enough that one or two feels like just the right amount of indulgence.
Expert Tips
Use room-temperature ingredients: Softened butter and room-temperature egg and mascarpone blend more smoothly and create a better texture in both the Peanut Butter Fudge Puddles and the filling.
Don't skip the chilling: Chilling the dough is essential. Without it, the dough will spread too much and won't hold the cup shape.
Press gently: When making the indent, press just enough to create a shallow cup. If you press too hard, the dough will be too thin on the bottom and might crack.
Let the chocolate cool slightly: If the melted chocolate is too hot when you fold in the mascarpone, it can make the filling too runny. Let it cool for a few minutes first.
Re-press after baking: The centers puff up during baking, so pressing them down again while they're still warm ensures you have enough room for the fudge filling.
FAQ
What is the best peanut butter to use for fudge?
Creamy, standard peanut butter like Jif or Skippy works best for these Peanut Butter Fudge Puddles. Natural peanut butter tends to separate and can make the dough too oily, which affects the texture. Stick with a well-mixed, sweetened variety for the most consistent results. My family always keeps a jar of Skippy in the pantry, and it's never let me down.
What is a fudge puddle?
A fudge puddle is a cookie cup filled with a smooth, creamy chocolate fudge center. The fudge "puddles" into the indent of the cookie, creating a rich chocolate pool in every bite. In this recipe, the mascarpone makes the fudge extra silky and keeps it from getting too firm or waxy when it sets.
Why does my Peanut Butter Fudge Puddles not set up?
If your fudge filling isn't setting, it might be because the chocolate wasn't fully melted or the mascarpone was too warm when you mixed it in. Make sure the chocolate is completely smooth before folding in the mascarpone, and let the filled cookies chill in the fridge for at least 30 minutes to help the filling firm up. Using room-temperature mascarpone, not warm or melted, also helps.
Why do you press a fork into peanut butter cookies?
Pressing a fork into traditional peanut butter cookies creates the classic crisscross pattern and helps flatten the dough so it bakes evenly. For these Peanut Butter Fudge Puddles, we skip the fork and use our thumb instead to create a little cup shape that holds the fudge filling. It's a different technique, but it makes these cookies extra special and fun to make.
