Sorry didn't see this post until this morning.
I add Molly McButter or Butter Buds to get that buttery flavor, skim milk and sugar free torani syrup. The flavors I have used are Almond Roca, Caramel and English Toffee . All good. The consistency gets a bit thicker sitting in the fridge but you can add a big of water to the oats before you nuke them and give them a good stir to re-hydrate. Even re-heated, these are scads better IMHO than rolled oats or those horrid prepackaged flavored ones. And you get MORE for the calories!
