- Preheat your oven to 375 degrees. This is a crucial step because starting with a hot oven ensures that your cookies bake evenly and rise beautifully.
- Line a cookie sheet with parchment paper or lightly grease it. This step prevents the cookies from sticking and helps them bake evenly.
- In a large bowl, whisk together flour, cocoa, baking soda, and salt. This mixture forms the dry ingredients that will give structure to your cookies. Set it aside.
- In another bowl, cream together light brown sugar, granulated sugar, butter, and peanut butter until the mixture is light and fluffy. This process incorporates air into the dough, helping the cookies rise.
- Add in the egg, vanilla extract, and coffee, and beat until well combined. The wet ingredients will enhance the richness of your cookie dough.
- Gradually stir in the dry ingredients until everything is just combined. Be careful not to overmix; this can make the cookies tough.
- Fold in the chopped pecans. This adds a lovely crunch to your cookies. Ensure they’re evenly distributed throughout the dough.
- Scoop out rounded tablespoons of cookie dough onto the prepared cookie sheet. Your dough will be thick, which is perfect for achieving a chewy texture.
- Flatten each cookie slightly with your hands. This will help them spread evenly while baking.
- Bake in the preheated oven for about 6 minutes, then remove them. The cookies will look slightly underbaked, which is what you want!
- Carefully press half a marshmallow, cut side down, into the top of each cookie. This adds a sweet, gooey surprise to the center.
- Return the cookies to the oven and bake for an additional 1 to 2 minutes. You want the marshmallows to soften but not melt completely.
- Remove from the oven and let them cool on the cookie sheet for a few minutes before transferring them to a cooling rack. This allows the cookies to set up a bit.
- In a medium bowl, melt chocolate chips in the microwave. Heat on high for 30 seconds, stir, and repeat until smooth. This will be your delicious topping.
- Add heavy whipping cream, butter, and another splash of vanilla extract to the melted chocolate. Stir until combined.
- Gradually stir in powdered sugar until you reach your desired frosting consistency. This frosting will be rich and creamy, perfect for drizzling over the cookies.
- Spoon the frosting over the top of each cooled cookie. Let it stand until the frosting has set. This final step makes your cookies look irresistible!
Notes
To store leftovers, keep your cookies in an airtight container at room temperature. They can stay fresh for up to a week. You can freeze the cookie dough before baking. Just scoop them onto a baking sheet, freeze until solid, then transfer to a zip-top bag. When ready to bake, just add a minute or two to the baking time.
