Chocolate and marshmallow cookies

1. Preheat the oven to 180°C (350°F) and line a baking sheet with parchment paper.
2. In a bowl, mix and sift together the dry ingredients: flour, unsweetened cocoa powder, salt, and baking soda.
3. In a large mixing bowl, place the softened butter, white sugar, and brown sugar. Beat with an electric mixer on medium speed until the mixture is creamy and smooth.
4. Add the egg and vanilla extract, and beat again until fully incorporated.
5. Gently fold in the dry ingredients with a spatula until you have a smooth, slightly sticky dough.
6. Using an ice cream scoop, portion out 12 balls of cookie dough and place them on the prepared baking sheet, leaving about 5 cm (2 inches) between each cookie. Bake 8 cookies per sheet if needed.
7. Bake the chocolate cookies in the preheated oven for about 8 to 10 minutes. Remove from the oven, press a whole marshmallow lightly into the center of each cookie, and return to the oven for an additional 2 minutes.
8. Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.

Chocolate Glaze

1.  In a small bowl, melt the chopped chocolate, either in a double boiler over a saucepan of simmering water or in the microwave in 20-second intervals, stirring until fully melted.
2. Add the oil and stir to combine.
3. Spoon a small teaspoon of chocolate glaze over each cookie, spreading it to fully cover the marshmallow.
4. Let the glaze set for a few minutes, then enjoy!
