Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.

Chop the cinnamon roll dough into bite-sized pieces, roughly 1-inch cubes.

In a mixing bowl, whisk together the eggs. Gradually add in the milk, vanilla extract, and ground cinnamon. Mix until combined.

Pour the custard mixture over the chopped cinnamon roll pieces and gently fold to ensure even coating.

Melt the unsalted butter in a saucepan and drizzle over the coated bites, mixing gently.

Spread the coated dough onto the baking sheet and bake for 15-18 minutes until golden brown.

Warm the maple syrup in a saucepan over low heat.

Allow the bites to cool slightly before dusting with powdered sugar and serving.
