These dark chocolate coffee mascarpone sandwich cookies are richly chocolatey and satisfyingly chewy. Sandwiched between the cookies is a silky coffee-mascarpone frosting made with instant espresso powder for a bright coffee kick.
The cookie dough comes together in one bowl, and the frosting pipes smoothly for tidy sandwich cookies. They’re dangerously easy to nibble—one more from the jar is inevitable.
I often buy larger-than-needed tubs of specialty ingredients and then invent new ways to use them. After making a chocolate coffee mascarpone tart with my first five-pound tub of mascarpone, I used the remaining cheese to develop a tiramisu-inspired sandwich cookie.
After three test batches I landed on a dark chocolate cookie with just the right density to hold a coffee-infused mascarpone filling. Balancing mascarpone and butter in the frosting took a bit of experimentation to prevent it from breaking, but the final result is smooth, flavorful, and pipes beautifully.
These dense, coffee-forward cookies pair perfectly with a morning cup of coffee, an afternoon pick-me-up, or an evening sweet treat. I’ve reached for them at all hours—they always satisfy.

Ingredient notes
*See the recipe card below for exact quantities.
Unsalted butter — Used melted in the cookie dough for a tender, chewy texture and softened for the frosting so it whips light and airy.
Brown sugar — Adds caramel notes and extra moisture, which keeps the cookies rich and soft.
Natural cocoa powder — Use natural (non-Dutch-processed) cocoa in the cookies so it reacts properly with the leavening and contributes a bright chocolate flavor.
Mascarpone cheese — The star ingredient for luxurious texture in both cookie and filling. Use it chilled straight from the refrigerator and stir it briefly to loosen before adding.
Espresso powder — Instant espresso powder concentrates coffee flavor without adding liquid. It gives the frosting a clear, bold coffee note.
Instructions
Combine melted butter, brown sugar, cocoa powder, and vanilla in a large mixing bowl and stir until fully blended.
Add the egg and mix until incorporated.
Fold in the chilled mascarpone until no streaks remain. Scrape the bowl to ensure even mixing.
Add the dry ingredients (flour, baking soda, baking powder, and salt) and mix just until combined. Chill the dough for 30 minutes so it’s easy to scoop.
Scoop leveled tablespoon portions (about 16 grams) and roll into balls. Place 12 balls per baking sheet, leaving room for spread.
Bake 12 cookies at a time at 350°F (177°C) for about 9 minutes, until they are flat and just beginning to firm at the edges; centers will still be slightly soft.
Right after removing from the oven, use a round cutter or the rim of a glass to nudge each cookie into a uniform circle while still warm. Cool on the sheet for 10 minutes, then transfer to a rack to finish cooling.
Repeat baking with remaining dough until all cookies are baked and cooled.
For the frosting, dissolve espresso powder into vanilla to make a smooth slurry.
Cream room-temperature butter for 2–3 minutes, then add sifted powdered sugar, the espresso slurry, and a pinch of salt. Beat on medium until light and fluffy.
Gently fold in the loosened mascarpone with a spatula—do not overmix to avoid breaking the mascarpone.
Transfer the frosting to a piping bag fitted with a large round tip.
Pipe tablespoon-sized rounds (about 18 grams) of frosting onto the underside of one cookie, then top with a matching cookie and press gently to spread the filling to the edges.
Place finished sandwiches on a sheet and chill until the filling sets. Store assembled cookies in an airtight container in the refrigerator.
Make ahead and storage instructions
Make ahead:
- Cookie dough: Make up to 3 days ahead in the refrigerator, or freeze for up to 3 months. Thaw overnight in the fridge before baking.
- Baked cookies: Bake ahead and keep unfrosted in an airtight container at room temperature up to 5 days, or freeze up to 1 month.
- Frosting: Make the coffee-mascarpone frosting up to 3 days ahead. For best results, pipe it into a bag, seal, and refrigerate. Let the filled bag sit at room temperature 30–60 minutes before piping. Important: do not re-whip the frosting, as mascarpone can separate and become grainy.
Frequently asked questions
Yes. The recipe used a leveled 1 tablespoon scoop (~16 grams) to produce 2 ¼ inch cookies that bake in about 9 minutes. You can scale up or down, but adjust spacing and baking time accordingly. Larger scoops will need more bake time (for example a 1½ tablespoon scoop bakes around 12 minutes), and smaller scoops bake slightly less. If you change the cookie size, you may also need to adjust the frosting amount per sandwich.
Variations
- Swap the coffee-mascarpone frosting for dulce de leche for a caramel-forward filling.
- Use the cookies as ice cream sandwich cookies—place small scoops of your favorite ice cream between two cookies and freeze until firm.
