Delicious Chocolate Oreo Marshmallow Cookies

Ensure all ingredients are at room temperature. This helps in achieving a uniform texture for your cookie dough.

Preheat your oven to 180 degrees Celsius (350 degrees Fahrenheit) and line a baking sheet with parchment paper.

In a mixing bowl, sift together the all-purpose flour, cocoa powder, baking powder, and salt.

This ensures there are no lumps and the ingredients are evenly distributed.

In another bowl, combine the softened unsalted butter, granulated sugar, and brown sugar. Use a mixer with a paddle attachment to beat them together until the mixture is light and fluffy.

This should take about 2-3 minutes. It's crucial for creating a good texture in your cookies.

Gradually add the egg to the butter mixture in three parts, mixing well after each addition.

Make sure all ingredients are well combined before moving to the next step.

Slowly add the sifted dry ingredients to the wet mixture. Mix until the dough is smooth and pulls away from the sides of the bowl.

Your dough should be thick and not too sticky.

Fold in the chopped dark chocolate, crushed Oreo cookies, and marshmallows until evenly distributed throughout the dough.

This adds texture and delicious flavor to your cookies.

Using a scale, portion out the dough into 12 balls, each weighing approximately 70 grams (2.5 ounces).

Place them on the prepared baking sheet, then flatten each ball slightly to form a disc shape.

Bake in the preheated oven for about 10 minutes.

The cookies should have a golden bottom, soft tops, and remain moist and chewy in the center. They will continue to firm up as they cool on the baking sheet.
