How to Make Chewy Chocolate Marshmallow Cookies
Preheat the oven: Start by preheating your oven to 350°F (175°C). Line two baking sheets with parchment paper to ensure the cookies don't stick.
Cream the butter and sugars: In a large mixing bowl, combine softened unsalted butter, granulated sugar, and light brown sugar. Beat them together until the mixture is light and fluffy, which usually takes about 2-3 minutes.
Add egg and vanilla: Crack in the egg and pour in the vanilla extract. Mix until fully combined, ensuring a creamy consistency that binds the ingredients well.
Combine dry ingredients: In a separate bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking soda, and salt. This step helps to evenly distribute the dry ingredients.
Mix wet and dry ingredients: Gradually add the dry mixture into the wet ingredients. Mix gently until just incorporated, being careful not to overmix to keep your cookies tender.
Fold in chocolate chips: Add in the semi-sweet chocolate chips, gently folding them into the dough for a rich chocolatey flavor throughout.
Prepare the marshmallow centers: Scoop about 2 tablespoons of the cookie dough and flatten it slightly. Place 3-4 mini marshmallows in the center, then wrap the dough tightly around them to enclose the marshmallows completely.
Place on baking sheets: Arrange the dough balls on the lined baking sheets, leaving about 2 inches of space between each ball to allow for spreading during baking.
Bake the cookies: Place the baking sheets in the oven and bake for 9-11 minutes. Look for the edges to be set while the centers remain soft - that's the perfect gooey texture!
Cool and enjoy: Once baked, allow the cookies to cool on the baking sheets for 5 minutes before transferring them to a wire rack. Serve warm for an unforgettable gooey experience.
Optional: Dust with powdered sugar for an extra touch of sweetness.
