While the Pumpkin Pie Blizzard took its turn in September, Dairy Queen is bringing a scary good Blizzard during October. The Royal Reese’s Brownie Blizzard is now available. Containing Reese’s Peanut Butter Cups and brownie pieces blended in vanilla soft serve, a peanut butter core is embedded in Royal Blizzard glory.  A small one of these will set you back 850 calories, so either opt for the Mini’s 530 calories or go for a jog to DQ instead of driving.
