I would like to bake some Reece's pieces into a chocolate cupcake. Just wondering if these should be added to the batter before dividing into cupcake liners or if it would be better to partially bake then add. Also, should these be tossed with flour before adding to the batter to prevent them from sinking? TIA

I buy the mini reese's baking pieces (like mini reeses pieces) and use them in my chocolate peanut butter cupcakes all the time. I mix them into the batter. They don't sink at all. Good luck.
