1-Getting started with this recipe is a breeze, and it only takes about 35 minutes total for a rewarding result. Begin by creaming the softened butter with both sugars until the mixture is smooth and fluffy this builds the base for that irresistible texture.

2-Next, stir in the beaten egg and vanilla extract to add moisture and flavor. In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt to blend the dry ingredients evenly.

3-Combine the dry mixture with the wet ingredients, then fold in 1/4 cup of chocolate chips for that double chocolate goodness. Chill the dough briefly in the refrigerator to help it hold its shape better during baking.

4-Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper or a silicone mat. Shape the dough into a mound on the baking sheet, then top it with 1 tablespoon of chocolate chips and sprinkles if you want a festive touch.

5-Bake for 18-22 minutes until the edges are set, and let it cool on the baking sheet for 5-10 minutes before serving. For tips like making smaller cookies, divide the dough to create 4 portions and bake for 9-10 minutes instead.
