M&M's and Oreo Chunks Cookies
Cream the butter and peanut butter with both sugars in a large bowl.
Beat in the vanilla and egg. Add the baking soda, salt, baking powder and cream of tartar, beat well until getting an uniform mixture.
Add the flour and stir until well combined.
Stir in the M & M's and the Oreos. Chill the dough for 1 hour.
Using a heaping tablespoon, drop the cookies about 5 cm from each other in a lined baking tray.
Bake on a previously pre-heated oven at 180°C for 12-15 minutes or until golden.
