To start, you’ll want to cream the butter and sugars together. You can do this with an electric mixer or by hand (but it’s easier with a mixer!). Creaming the butter and sugars until smooth and light is crucial for getting that chewy, soft texture in the finished cookies. This usually takes about 3-4 minutes, so be patient!

Once the butter and sugars are fully mixed, you should see a light, fluffy texture. This will help give your cookies a soft and chewy texture when they’re baked.

Now it’s time to add the eggs and vanilla extract. Beat the mixture until the eggs are fully incorporated and the batter looks smooth. The vanilla brings out that warm, comforting flavor that reminds you of sitting by the fire with a mug of cocoa. Don’t rush this step, as the vanilla really adds to the overall flavor of the cookies.

In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt. Make sure everything is evenly distributed. You don’t want clumps of cocoa powder in your dough, so it’s important to sift or whisk the dry ingredients together.

Slowly add the dry ingredients into the wet ingredients, mixing as you go. Be careful not to overmix, as this can result in tough cookies. You’ll know the dough is ready when it comes together into a thick, chocolatey mass.

Now for the fun part—add the mini marshmallows and chocolate chips! These are the stars of the show, and they’ll make your cookies absolutely irresistible. Stir them gently into the dough, making sure they’re evenly distributed.

The marshmallows will get soft and melty while baking, which gives the cookies that gooey, marshmallowy bite we all love. And of course, the chocolate chips add extra pockets of rich, melty chocolate.

Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper or a silicone baking mat. Now, scoop about 2 tablespoons of dough for each cookie and place them onto the prepared baking sheet. Leave a little space between each cookie, as they will spread out as they bake.

Bake the cookies for 8-10 minutes. You’ll know they’re done when the edges are set but the centers are still soft. The cookies will continue to cook slightly on the baking sheet once you take them out of the oven, so don’t worry if they’re a little soft in the middle!

Once the cookies are out of the oven, let them cool on the baking sheet for about 5 minutes. This helps them firm up a little. Then, transfer the cookies to a wire rack to cool completely. But if you can’t wait (and I don’t blame you), go ahead and enjoy one while it’s still warm—just be careful, because that marshmallow center will be hot!
