Preheat oven to 400°F. Line a baking sheet with parchment paper and set aside.
With a fork, stir the chicken, garlic, ranch, egg, breadcrumbs, and ranch together until mixed. Using a cookie portion scoop (or your hands), mold the mixture into meatballs.
1 pound lean ground chicken, 2 cloves garlic, 1 large egg, ½ cup Italian-style breadcrumbs, 1 tablespoon ranch seasoning
Press a cube of blue cheese into the center of each meatball then fold the mixture around the cheese and press together. Roll into a ball so that the cheese is completely covered.
¼ cup blue cheese crumbles
Place meatballs on the prepared baking sheet and bake for 16-18 minutes or until golden and cooked through.
Place the meatballs in a slow cooker with the butter and buffalo wing sauce. Place on high for about 20 minutes until hot. Keep on warm while serving.
2 tablespoons unsalted butter, 1 cup Buffalo sauce
