Combine 4 cups spiced apple cider, 2 cups frozen Oregon raspberries, and 2 cups frozen Oregon Marion berries in the crockpot and heat on high for one hour. Strain hot cider through a fine mesh sieve and add strained cider back to the crockpot.
Keep berry cider on warm or low setting (depending on how hot you want it). Top with 1 cup whipped cream and cinnamon to serve.
Notes
To make a spiked hot berry cider, serve along with your favorite spiced rum or vodka!
