Ingredients

1/2 cup unsalted butter, softened — Adds richness and helps create a tender, slightly crisp cookie edge.
1/2 cup packed light or dark brown sugar — Contributes moisture, chewiness, and caramel notes.
1/2 cup granulated sugar — Adds sweetness and helps spread control for the cookie cups.
1 large egg — Binds the dough and adds structure and moisture.
2/3 cup creamy peanut butter — Brings peanut flavor, fat, and chewiness to the dough.
1 teaspoon pure vanilla extract — Rounds out flavor and enhances the sweetness.
1 and 1/4 cups all-purpose flour — The structure for the cookie; measure by spooning and leveling for accuracy. See a basic method for working with simple cookie dough in this butter cookie guide.
1/2 teaspoon baking soda — Provides lift and a bit of chew.
1/2 teaspoon salt — Balances sweetness and enhances overall flavor.
8 ounces semi-sweet chocolate, chopped — The base for the fudge filling, provides chocolate intensity.
1 teaspoon vegetable oil or coconut oil — Keeps the melted chocolate glossy and smooth.
8 ounces mascarpone cheese — Makes the filling silky, tangy, and creamy.
1/2 cup Heath toffee bits or chopped peanuts (optional) — Optional crunchy topping to finish each cup.

Step-by-Step Instructions

In a large bowl, cream the softened butter, 1/2 cup packed brown sugar, and 1/2 cup granulated sugar until light and creamy, about 2 to 3 minutes. A stand mixer or hand mixer works well. Tip: scraping the bowl down once helps ensure even mixing.
Add the large egg and mix until combined and smooth.
Mix in the 2/3 cup creamy peanut butter and 1 teaspoon pure vanilla extract until the dough is uniform and smooth.
Gradually add the 1 and 1/4 cups all-purpose flour, 1/2 teaspoon baking soda, and 1/2 teaspoon salt. Mix until just combined. Chill the dough for at least 1 hour to make it easier to shape and to prevent excessive spreading during baking. For shaping help, you can review basic creaming and shaping techniques from this butter cookie resource.
Preheat the oven to 325°F and grease mini muffin pans well to prevent sticking.
Form the chilled dough into balls about 1 inch in diameter and place one in each greased muffin cup. Use your thumb or the back of a small spoon to press an indent into the center of each ball, creating a well for the filling.
Bake the cookie cups at 325°F for 14 to 15 minutes, or until the edges are set and lightly golden. Small pans vary, so watch the first pan closely.
Remove the pans from the oven, cool slightly, and use the back of a spoon to press the indents again if they puffed up while baking. Let the cookie cups cool completely in the pan so they hold their shape.
For the fudge filling, place the 8 ounces semi-sweet chocolate and 1 teaspoon vegetable oil or coconut oil in a microwave-safe bowl or double boiler. Melt gently until smooth, stirring frequently to avoid scorching.
Off the heat, fold in the 8 ounces mascarpone cheese until the mixture is smooth and glossy. Spoon or pipe the fudge filling into each cooled cookie cup. Sprinkle the optional 1/2 cup Heath toffee bits or chopped peanuts on top if desired. Chill briefly if you prefer a firmer filling.

Tips, Storage & Variations

Tips
- Use well-chilled dough for clean shaping and minimal spread.
- If indents puff in the oven, press them again right after baking while warm, then cool fully.
- For easier filling, transfer the fudge to a piping bag or a resealable plastic bag and snip a corner.
- For more chocolate contrast, you can stir a few chopped chocolate pieces into the filling as it cools, inspired by ideas from chocolate cookie recipes.
Storage
- Store finished cookie cups in an airtight container in the refrigerator for up to 5 days to keep the mascarpone filling fresh.
- Bring to room temperature for 15 to 20 minutes before serving for the creamiest texture.
Freezing
- Freeze baked but unfilled cookie cups in a single layer on a baking sheet, then transfer to a freezer-safe bag for up to 2 months. Thaw before filling.
- Filled cookie cups can be frozen for up to 1 month. Wrap gently to prevent condensation on the filling during thawing.
Flavor Variations Using Existing Ingredients Only
- Toffee crunch: Top each filled cup with Heath toffee bits for an extra crunchy finish.
- Peanut crunch: Sprinkle chopped peanuts on top for more peanut texture and flavor.
- Extra peanut butter note: Press a tiny drop of extra peanut butter into the center before piping the fudge for a double peanut hit.

Frequently Asked Questions (FAQ)

How many cookie cups does this recipe make?

About 24 mini cookie cups, depending on the size of your mini muffin pan.

Can I skip chilling the dough?

Chilling is recommended. It firms the dough so the cups hold their shape and do not spread too much.

Can I make the cookie cups ahead of time?

Yes. Bake the cups ahead and store unfilled in the freezer, then fill them the day you plan to serve.

How do I prevent the filling from being runny?

Chill the filling briefly after assembling to firm it up, and use a small amount of oil when melting the chocolate to keep it glossy but not loose.

Is mascarpone necessary for the filling?

Mascarpone gives a silky texture and gentle tang. Substituting changes flavor and texture, so use mascarpone if you want the same result.

Can I use chopped chocolate instead of chips?

Yes. Finely chopped semi-sweet chocolate melts smoothly and works well for the fudge filling.
