Method
 

Step 1: Cream butter & sugars
  1. Beat butter, granulated sugar, and brown sugar together for 2–3 minutes, until light and fluffy.
Step 2: Add eggs & vanilla
  1. Mix in eggs and vanilla until smooth.
Step 3: Add the color
  1. Add blue gel food coloring (start with ½ teaspoon and add more until bright Cookie Monster blue).
  2. Mix well so the color is evenly incorporated.
Step 4: Add dry ingredients
  1. Whisk flour, baking soda, baking powder, and salt.
  2. Add to the wet mixture and mix until a thick dough forms.
Step 5: Add the mix-ins
    Fold in:
    1. Chocolate chips
    2. Crushed Oreos
    3. Mini cookies
    4. Save a handful of each for topping.
    Step 6: Scoop & shape
    1. Scoop large 3–4 tablespoon balls (Crumbl-style thickness).
    2. Press a few extra cookie pieces or Oreo halves into the tops.
    Step 7: Bake
    1. Preheat oven to 350°F (175°C).
    2. Line baking sheets with parchment.
    3. Bake 10–12 minutes, until edges are set but centers look slightly soft.
    4. Let cookies cool on the tray 10 minutes — they finish setting as they cool.

    ❓ 10 FAQs

    Gel gives a brighter, more vibrant blue without thinning the dough.

    They’re classic for this cookie, but you can swap with other sandwich cookies.
