Marshmallow Hot Chocolate Mug Cookies
These Marshmallow Hot Chocolate Mug Cookies are basically everything you love about a cozy mug of hot cocoa, turned into a warm chocolate cookie. Each little cookie is soft in the middle, rich with cocoa, and finished with melty marshmallows for that classic winter treat feeling.
Ingredients
- 4 tablespoons unsalted butter softened
- ¼ cup packed brown sugar
- 2 tablespoons granulated sugar
- 1 large egg yolk
- ½ teaspoon vanilla extract
- ½ cup + 2 tablespoons all-purpose flour
- 2 tablespoons unsweetened cocoa powder
- ¼ teaspoon baking powder
- Pinch of salt
- 4 Oreo cookies roughly crushed
- ¼ cup semi-sweet chocolate chips
- ½ cup mini marshmallows
Instructions
- Prepare the mugs: Preheat oven to 350°F (175°C). Lightly grease two oven-safe mugs or ramekins and place them on a baking sheet.
- Make the dough: Mix softened butter, brown sugar, and granulated sugar until creamy. Stir in the egg yolk and vanilla.
- Add dry ingredients: Whisk flour, cocoa powder, baking powder, and salt separately. Stir them into the butter mixture just until combined.
- Add chocolate: Fold in crushed Oreos and chocolate chips. Divide the dough evenly between the two mugs without packing it down.
- Bake: Bake for 12–15 minutes, until the edges are set but the centers remain slightly soft.
- Add marshmallows: Top with mini marshmallows and bake for another 1–2 minutes, until soft and lightly toasted. Cool for 5 minutes and serve warm.
