    These adorable Cookie Monster treats will bring a smile to any face! They're chewy blue goodies packed with chunks of white chocolate, broken-up Chips Ahoy and crushed Oreos - that's right, cookies stuffed with other cookies! They're just what you need for children's celebrations or anyone with a soft spot for that lovable blue Sesame Street character.

Achieving That Vibrant Blue

    Nailing that authentic Cookie Monster shade took quite a bit of kitchen testing! What I found works best is a mix of violet, royal blue and electric blue food coloring. Why add purple? It actually helps balance out the yellowish tint from your eggs and butter, creating that bright, cartoon-worthy blue we want.

Gather Your Supplies

  • Base Dry Goods: All-purpose flour with cornstarch for extra tenderness.
  • Warmed Elements: Let your eggs and butter sit out first!
  • Sweeteners: You'll need both white and brown sugar types.
  • Coloring Agents: Three different blue/purple shades for the right look.
  • Mix-in Goodies: White chocolate pieces, crumbled Oreos, tiny Chips Ahoy.

Baking These Monsters

Prep Work First
Set your oven to 350°F and get your cookie sheets covered with parchment or silicone liners. Remember to take out your cold stuff early so it warms up!
Combine Dry Ingredients
Toss your flour, cornstarch, baking soda and salt in a bowl and whisk them together. This step means you won't find any flour clumps in your finished treats!
Work The Butter Mix
Beat the softened butter with your sugars until it's airy and pale, taking about 2 minutes. Drop in eggs and vanilla, mixing just enough to blend everything together.
Add The Blues
Slowly work in your dry mixture, then add your three colorings. Don't stress if it seems too bright at first - it'll look perfect after baking! Keep going until your dough is nicely thick with even color.
Throw In Chunks
Now fold in your white chocolate bits, broken Oreos and Chips Ahoy pieces. Keep some aside to stick on the outside - makes them look extra tasty.
Form Your Cookies
Roll the blue dough into 2-tablespoon balls. Push extra cookie chunks and chips all around the outside to create that messy Cookie Monster appearance.
Into The Oven
Place about 8 balls on each tray with good spacing. Bake for 10-12 minutes, taking them out while still soft - we don't want any browning! Bake one tray at a time for best results.
Cool Down Stage
Let them sit right on the hot pan for 15 minutes since they're very fragile at first. Once they've firmed up, move them to a cooling rack.

Nailing The Details

    Get your flour measurement right - lift it with a spoon first, scoop it gently, then level it off. Too much makes dry cookies. Always use parchment or a silicone mat or you'll have a sticky mess. Want them even cuter? Stick some candy eyeballs on top before they go in the oven!

Try These Twists

    Switch up the cookie chunks with whatever you've got - even homemade chocolate chip works wonderfully! Experiment with different chips - try milk, dark or white chocolate combos. Looking for an extra surprise? Tuck a square of chocolate bar into the middle of each ball for a melty center when baked!

Storage Tips

    They'll stay tasty in an airtight container for around 3 days - stick them in your fridge and they'll last even longer. Need to prep early? The dough freezes great for up to 3 months - just let it thaw before adding the outer toppings and popping them in the oven.
