Cinnamon Coffee Roll Pancakes

In a small bowl, mix together the dairy-free milk and apple cider vinegar, then set aside for 10 minutes. To make the coffee cinnamon swirl, whisk together the melted vegan butter, brown/coconut sugar, cinnamon, ground coffee, and gluten-free all-purpose flour into a bowl. In a separate large bowl, mix together all of the dry ingredients for the pancakes. Add the milk mixture to the dry ingredients along with the rest of the wet ingredients. Gently fold together with a rubber spatula, being careful not to over mix. When frying the pancakes, drizzle the coffee cinnamon filling onto the pancake side facing up with a small spoon or piping bag. Then flip and continue cooking until golden brown.
