In a medium sized bowl combine your all-purpose flour, baking powder, and salt, and whisk together. Set aside.

In a separate, large bowl, combine oil, white sugar, and brown sugar, and vanilla, use a hand mixer to cream it together.

Add flour mixture to the large bowl with sugar mixture, combining it a little at a time, and mixing with a hand mixer, until combined. The dough will be very thick.

Stir in the M&M's and use your hands to work them into the dough.

Cover the dough and place it in the refrigerator for 2-3 hours to chill.

Once completely chilled, dough should be thick and scoopable. Remove it from fridge, and at this time preheat the oven to 350 degrees F.

Use a cookie scoop or your hands to form 1 inch balls of dough.

Put the confectioner's sugar into a shallow dish, and roll each of the dough balls around in the powdered sugar until it is completely covered.

Place cookies on a parchment lined baking sheet, leaving at least 2 inches between each one.

Bake in preheated oven for 9-10 minutes.

Let cookies rest on the baking sheet for 5 minutes after baking, then remove to a cooling rack.

Let cool, and enjoy!
