Heat a large nonstick skillet or griddle over medium to medium-low heat, greasing lightly with butter. Use a 1/3-cup measure or a large cookie scoop to pour pancake batter onto the pan.
Using the piping bag, create a cinnamon swirl starting from the center of each pancake and spiraling outward. Try to keep the swirl away from the edges to prevent it from spilling over.
Cook until bubbles form on the surface, about 2 to 3 minutes. Flip the pancakes carefully and cook the other side for 1 to 2 minutes, until golden brown and fully cooked. Adjust the heat as needed to prevent burning.
Transfer finished pancakes to a baking sheet and keep warm in a 200°F oven while you cook the remaining batches. Wipe the skillet between batches if necessary.
Serve the pancakes warm with homemade cream cheese glaze (below), maple syrup, or whipped honey cinnamon butter, if desired. Enjoy!
