Turn the oven on to 350°F. Combine butter and both sugars in a large bowl, beating for about a minute until they're blended well.

Mix in the eggs and vanilla until the texture turns pale, fluffy, and light. This should take about 3 minutes. Add a few drops of blue food dye, going as vibrant as you'd like for that Cookie Monster look!

Pour in the baking powder, salt, and flour and mix just enough so you can't see white flour streaks anymore. Don't overwork it; gentle mixing works best here.

Carefully stir in the semi-sweet chocolate chips, white chips, crumbled Oreos, and crispy mini cookies. If the dough feels too sticky, chill it for half an hour before using.

Scoop out 2 tablespoons of dough, flatten it, and pop a piece or two of milk chocolate in the middle. Wrap the dough around the chocolate to cover it, then make a sandwich with 2 more tablespoons of dough on top, sealing the edges.

Stick extra chips, Oreo crumbs, and cookie pieces on top of each cookie ball. This makes them look extra packed with goodies.

Lay the cookies on parchment-lined or greased trays, leaving lots of space in between for spreading. Bake 10-12 minutes, then cool on the tray for 5 minutes before moving to a rack.
