Tiramisu Toast

Instructions

• Gather ingredients. Preheat the oven to 375 degrees F (190 degrees C). Line a baking pan with aluminum foil.
• Crack egg into a baking dish. Add white sugar, espresso, and vanilla extract. Whisk to combine. Place bread slices into the dish and toss in the mixture to saturate; let sit for 10 to 15 minutes to fully absorb.
• Transfer bread slices to the prepared pan and drizzle any accumulated coffee mixture liquid over top.
• Bake toast in the center of the preheated oven until custard is cooked and bread bounces back slightly when touched, 20 to 25 minutes. Transfer slices to a wire rack to cool to room temperature.
• Meanwhile, pour wine into a saucepan. Add sugar and cook over medium heat until reduced to about 1 tablespoon. Remove from heat and let cool.
• Place mascarpone cheese into a bowl and add cooled wine reduction and a very small pinch of salt. Stir with a spatula until combined. Chill before piping or spreading on cooled toast. Top with shaved chocolate.
