With dark roasted coffee, rich molasses, and balsamic vinegar. This sauce makes our favorite Slow Cooker Coffee Meatballs! Just add Homestyle frozen meatballs into a crockpot and cover with 1 bottle of Captain Rodney’s Coffee BBQ Sauce, heat on high till warm, stirring occasionally. Turn down to warm once meatballs are heated through! That’s it! Just dump, pour, heat & serve!
