Ingredients
- All-purpose flour: 1 1/2 cups
- Creamy peanut butter: 1 cup
- Unsalted butter (softened): 1/2 cup (1 stick)
- Light brown sugar (packed): 1/2 cup
- Granulated sugar: 1/2 cup
- Large egg: 1
- Baking soda: 1 teaspoon
- Mini marshmallows: 1 1/2 cups
Instructions
- Step 1: Preheat the oven to 375°F (190°C). Line two large baking sheets with parchment paper. In a large bowl, cream together the softened butter, peanut butter, brown sugar, and granulated sugar using an electric mixer until light and fluffy.
- Step 2: Beat in the egg and vanilla powder until just combined. In a separate bowl, whisk together the flour and baking soda. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until a cohesive dough forms.
- Step 3: Scoop the dough using a 1.5 to 2-tablespoon cookie scoop and place the balls 2 inches apart on the prepared baking sheets. Bake for 8 minutes until the edges are just set but the centers are still soft.
- Step 4: Remove the baking sheets from the oven. Carefully and quickly press 5-7 mini marshmallows onto the surface of each partially baked cookie.
- Step 5: Return the cookies to the oven and bake for an additional 3 to 5 minutes, or until the marshmallows are puffed, gooey, and lightly golden brown. Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
Notes
- Store cooled cookies in an airtight container for up to 3 days, using parchment paper between layers to prevent sticky marshmallows from fusing together.
- To restore the gooey texture, microwave an individual cookie for 10 to 15 seconds or warm it briefly in a 300°F oven for 2 minutes.
- Serve these rich, salty-sweet cookies alongside a tall, ice-cold glass of milk or a robust mug of hot coffee to balance the richness.
- The short 8-minute initial bake is critical; work quickly when pressing the marshmallows into the hot cookies and return them to the oven immediately so the residual heat helps them puff up beautifully.
