For chocolate chip cookie

  • 6 Tbsp Butter, salted (room temperature)
  • 6 Tbsp Light brown sugar
  • 2 Tbsp Granulated sugar
  • 2 Tbsp Egg (room temperature)
  • 1 tsp Vanilla extract
  • ½ Cup Bread flour
  • ½ cup Cake flour
  • ½ tsp Baking soda

For brownie

  • ¼ Cup Butter, salted (room temperature)
  • 6 Tbsp Granulated sugar
  • ½ Cup All-purpose flour
  • 3 Tbsp Unsweetened cocoa powder
  • 2 Tbsp Egg (room temperature)
  • 1 Tbsp Baking chocolate
  • 1 tsp Vanilla Extract

For topping and stuffing

  • 1 cup Rainbow sprinkles
  • ½ Cup Milk chocolate chips
  • ⅓ Cup White chocolate chips


  • 1) For Brownie-
    1. Sift together flour and cocoa in a small bowl and set it aside.
    2. In a small sauce pan add butter, chocolate and sugar. Heat it on low (stirring continuously) till everything melts well. Cool it to room temperature.
    3. Now beat egg and vanilla in this mixture. Add dry ingredients and fold only till combined.
    4. Cover and chill in fridge (preferably for 4-5 hrs) or in freezer until very cold and the chocolate is set if in a rush.
    2) For chocolate chip cookie-
    1. Sift both flours and baking soda. Set aside.
    2. Beat butter and sugar until light and fluffy, about 2-3 minutes with a hand beater. Add egg and vanilla and beat for another minute on high.
    3. Now slowly add in the flours and mix only till combined.
    3) Cookie dough assembly:
    1. Take half of chocolate chip cookie dough, roll it into a ball and flatten it into a disc of about 5 inches. I do this on parchment paper. Makes it so easy to rotate and shape the disc. Create two such discs.
    2. Spread half of the brownie batter on top of this disc. If you have chilled this batter, it should form into a dough ball. I baked my cookie within 45 minutes of making and so I chilled it in the freezer after spreading the brownie batter on the chocolate chip cookie dough disc. Either way make sure brownie batter is super cold and extremely firm to touch. This will be about 4 inches.
    3. Now the fun part. Creating a concave area in the center, Pour your sprinkles on the brownie disc. Remember not to spread them too wide, instead create a heaping pile. Save about 3 Tbsps of sprinkles for topping on the cookie. Press some milk chocolate chips on the edges of brownie disc.
    4. Seal with the remaining two discs, brownie first and then chocolate chip cookie dough. Pinch the cookie to seal well on the edges. Top with milk chocolate chips and the remaining sprinkles.
    5. Chill for about 30 minutes and bake in a pre-heated oven at 350 deg F for about 20-25 minutes or until the edges appear set and golden brown in color.
    6. Cool the cookie for 15-10 minutes on sheet before moving to wire rack. I press my white chocolate chips while the cookie is cooling on the sheet. This way they don't catch any color and appear all melty and pretty!


  1. Chill the cookie for 1-2 hours in the fridge if not in a rush to bake. This step ensures a thick cookie.
  2. If you don't wish to bake your cookie in 30 minutes, you may store it in the fridge for a few hours and upto 3 days. Cover it with a foil and bake when you are ready. Chilling them in the refrigerator enhances their flavor and texture considerably! And I can't recommend it enough.
