Hot Chocolate Cookies

from Pennies on a Platter
Yield: 3 1/2 dozen cookies
Serving Size: 2 cookies

1 cup unsalted butter, at room temperature
1 cup granulated sugar
2/3 cup brown sugar
2 eggs
1 teaspoon vanilla extract
3 1/4 cups all-purpose flour
4 packages (or 1/2 cup plus 3 Tablespoons) Hot Chocolate Mix (store-bought or homemade)
1 1/4 teaspoon baking soda
1 teaspoon salt
1 cup miniature semi-sweet chocolate chips
2 cups miniature marshmallows

Preheat the oven to 350 degrees F. Line baking sheets with parchment paper or silicone mat.
In a large mixing bowl, cream together the butter and sugars until light and fluffy. Beat in the eggs, one at a time, then blend in the vanilla.
In a separate medium bowl, whisk together the flour, hot chocolate mix, and baking soda and salt. Slowly add to the wet ingredients and mix just until combined, scraping the sides of the bowl as needed. Fold in the chocolate chips.

Drop dough balls onto the prepared cookie sheets and bake for 7 minutes. Remove the cookies from the oven. Working quickly, carefully add about 5 to 7 miniature marshmallows to the top of each cookie, and gently press. Return to the oven and bake an additional 2 to 3 minutes, or until the marshmallows start to puff. Remove from the oven and let cool on the cookie sheets for 10 minutes before removing. Transfer to a wire rack to cool completely.
