Sift first 4 ingredients into a bowl. Add brown sugar and pecans. Combine eggs, milk, vanilla, melted butter and Choc Melts, add to dry ingredients, mix lightly. Add White Bits, stir to combine. DO NOT OVERMIX, it should be lumpy.
Fill greased muffin pans 2/3 full and bake at 375 degrees F for 20-25 minutes.
NOTE: Nestle's Melts are cooking chocolate that come in a button shape, easier to melt and weigh than blocks. Nestle's Bits are morsels of pure chocolate, so they hold their shape when baked.
