Open the can and set the icing aside. Cut each cinnamon roll into 4 bite-sized pieces, keeping them round to hold their shape when cooked.
In a medium bowl, whisk together the eggs, milk, vanilla extract, and cinnamon until smooth.
Dip each cinnamon roll piece into the egg mixture, coating it fully. Let the excess drip off before placing it in the skillet.
Melt 1 tablespoon of butter in a non-stick skillet over medium heat. Add the dipped bites in a single layer. Don’t overcrowd—cook in batches if needed.
Cook for 2–3 minutes per side until golden and crisp outside, and cooked through in the center. Remove and set aside.
Microwave the reserved icing for about 10 seconds until it’s smooth and pourable.
Plate the warm French toast bites, drizzle with icing, sprinkle with powdered sugar (optional), and serve with maple syrup for dipping.
