Whether for a party, a late-night dessert, or just a sweet craving, these cookies are guaranteed to be a hit.


Ingredients

  • ½ cup (1 stick) unsalted butter, softened

  • ¾ cup brown sugar

  • ¼ cup granulated sugar

  • 2 large eggs, room temperature

  • 1 tsp vanilla extract

  • ½ cup unsweetened cocoa powder

  • 1 cup all-purpose flour

  • ½ tsp baking soda

  • ¼ tsp salt

  • ½ cup semi-sweet or dark chocolate chips

  • ¼ cup rainbow sprinkles


Instructions

  1. Preheat & Prepare

    • Preheat your oven to 350°F (175°C).

    • Line a baking sheet with parchment paper.

  2. Cream the Butter & Sugars

    • In a large mixing bowl, cream together butter, brown sugar, and granulated sugar until light and fluffy (about 2 minutes).

  3. Add Eggs & Vanilla

    • Mix in the eggs one at a time, beating well after each addition.

    • Stir in the vanilla extract.

  4. Combine Dry Ingredients

    • In a separate bowl, whisk together cocoa powder, flour, baking soda, and salt.

    • Gradually mix the dry ingredients into the wet ingredients until just combined (do not overmix).

  5. Fold in Chocolate Chips & Shape the Cookies

    • Gently stir in chocolate chips.

    • Scoop tablespoon-sized portions of dough onto the prepared baking sheet, leaving 2 inches of space between each cookie.

  6. Bake to Perfection

    • Bake for 10-12 minutes, until the edges are set but the centers look slightly underbaked.

    • Remove from the oven and let the cookies sit on the baking sheet for 5 minutes before transferring to a wire rack.

  7. Decorate with Sprinkles

    • While the cookies are still warm, sprinkle rainbow sprinkles on top and gently press them in so they stick.

  8. Cool & Serve

    • Let cookies cool completely on a wire rack before storing.

    • Enjoy warm with a glass of cold milk or vanilla ice cream for an indulgent treat!

Notes

  • For extra gooey cookies, underbake them by 1-2 minutes and let them firm up as they cool.

  • Customization Ideas:

    • Add chopped walnuts or almonds for a nutty crunch.

    • Drizzle melted chocolate over the cookies before adding sprinkles.

    • Swap rainbow sprinkles for mini M&M’s for a fun twist!

  • Store in an airtight container at room temperature for up to 5 days.
