Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

For the Cookies:

• 1/2 cup (115g) unsalted butter, softened
• 3/4 cup (150g) granulated sugar
• 1 large egg
• 1 tsp vanilla extract
• 1 1/4 cups (160g) all-purpose flour
• 1/2 tsp baking powder
• 1/4 tsp baking soda
• 1/4 tsp salt

For the Topping:

• 1/2 cup (120ml) heavy cream
• 1 cup (175g) semi-sweet chocolate chips
• 1/2 cup marshmallow creme or fluff

Directions

1. Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.
2. In a mixing bowl, cream the softened butter and sugar until light and fluffy.
3. Add the egg and vanilla extract, and mix until well combined.
4. In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
5. Gradually add the dry ingredients to the wet mixture, mixing just until a soft dough forms.
6. Scoop dough into balls and place them on the prepared baking sheet, spacing them apart. Gently flatten each one.
7. Bake for 9–11 minutes, or until the edges are lightly golden. Let the cookies cool completely on a wire rack.
8. Meanwhile, heat the heavy cream in a saucepan until it just begins to simmer. Remove from heat and pour over the chocolate chips in a heatproof bowl.
9. Let the mixture sit for 1 minute, then stir until smooth to make a ganache.
10. Spoon a dollop of ganache onto each cooled cookie.
11. Using a piping bag or spoon, swirl marshmallow creme over the ganache in a spiral pattern.
12. Let the topping set slightly before serving, or chill for firmer texture.
