In a large mixing bowl, beat together the butter, brown sugar, granulated sugar, and vanilla until combined. Beat in the eggs and 1 egg yolk, 1 at a time, until combined. Add the flour, baking soda, baking powder, and salt. Beat in the oats. Fold in 1 cup of the M&M's, the pretzels, chocolate chips, and white chocolate. Roll the dough into 1/4 cup size balls. Place 6 inches apart on the prepared baking sheet. Transfer to the oven and bake for 8 minutes, then rotate the pan and bake another 4-6 minutes or until they look cooked in the middle.
