Begin by preparing your sourdough loaf. Using a sharp knife, slice the bread into very thin pieces, about 1/8 inch thick.

Take a generous amount of buttercream frosting and spread a thin layer on both sides of each sourdough slice. Sprinkle a light dusting of sugar on each side.

Preheat your griddle or skillet over medium heat to 325°F (160°C). Ensure the surface is evenly heated.

Place the prepared bread slices on the hot griddle. Cook each slice for about 2 minutes on one side, then flip and cook for another 2 minutes.

After cooking, remove the slices from the griddle and transfer them to a silicone-lined baking sheet. Allow them to cool for a few minutes.
