• Preheat the oven to 350°F. While it's warming up, get a baking sheet and line it with parchment paper.

Cookie Dough

• In a large bowl, you're going to mix the softened butter and sugar together until it forms a smooth mixture. Add the eggs in one at time, beating them slowly. Stir in the vanilla extract.
• In a separate bowl, mix the dry ingredients. Combine the flour, cocoa powder, baking soda, and salt. Once mixed, gradually add it to the wet ingredients and mix them all together.
• Drop rounded tablespoons of the dough onto the prepared baking sheet. Bake for 8 minutes.
• Once you take them out of the oven, immediately top each cookie with half a marshmallow. Return it to the oven to cook for 2 minutes. After, remove from the oven and let them cool.

Chocolate Drizzle

• In a heat-proof bowl, melt the chocolate chips with milk or cream over a pot of simmering water. You can also melt them in the microwave using 20-second intervals. Just continue to stir until smooth.
• Allow the cookies to cool slightly and then spoon (or drizzle) the melted chocolate on top of the marshmallows in the cookies.
• As hard as it will be to do, give the cookies about 15 minutes to rest. They're best enjoyed while slightly warm so don't be shy!
