Prepare the Heart Shapes: Using a small heart-shaped cookie cutter, cut out hearts from each slice of bread. Save the scraps for another recipe (like breadcrumbs or croutons).

Make the Batter: In a shallow bowl, whisk together eggs, milk, vanilla extract, cinnamon, and sugar until well combined.

Cook the French Toast Hearts: Heat a large skillet or griddle over medium heat and lightly grease with butter or oil. Dip each heart-shaped bread piece into the egg mixture, letting any excess drip off. Place the soaked bread hearts onto the skillet and cook for 2-3 minutes per side, or until golden brown and cooked through. Work in batches if necessary.

Coat with Churro Mixture: In a shallow dish, mix granulated sugar and cinnamon for the churro coating. While the French toast bites are still warm, gently toss them in the churro coating until fully covered.

Serve and Garnish: Arrange the French Toast Churro Bites on a serving platter. Serve with chocolate or caramel sauce for dipping and a dollop of whipped cream, if desired.
