Ingredients

Scale

Ingredients

  • 1 slice of bread (preferably slightly stale or thicker-cut such as brioche, challah, or Texas toast)
  • 1 large egg
  • 3 tablespoons of milk (whole milk, skim, or plant-based alternatives like almond or oat milk)
  • 1 tablespoon of maple syrup or sugar (granulated sugar, brown sugar, or honey also works)
  • ¼ teaspoon of ground cinnamon
  • A pinch of salt
  • ½ teaspoon of butter

Instructions

  1. Prepare the Mug: Place ½ teaspoon of butter into a large microwave-safe mug (at least 12 ounces). Microwave on high for 20-30 seconds until melted, then swirl the butter around to coat the bottom and sides, preventing sticking.
  2. Create the Custard: Crack the egg into the buttered mug. Add 3 tablespoons of milk, 1 tablespoon maple syrup or sugar, ¼ teaspoon cinnamon, and a pinch of salt. Whisk vigorously with a fork inside the mug until the mixture is uniform in color and slightly frothy.
  3. Prepare the Bread: Tear or cut the bread slice into bite-sized cubes about 1 inch in size to maximize custard absorption.
  4. Combine and Soak: Add bread cubes to the mug and gently press down with the fork to submerge all pieces in the custard. Let it sit for 30-60 seconds to allow full absorption, using the longer time for drier or thicker bread types.
  5. Microwave: Place the mug in the center of the microwave and cook on high power for 1 minute. Check the state of the French toast, then continue cooking in 15-second intervals until the top is puffed, springy to the touch, and no visible liquid remains, totaling about 1 minute 15 seconds to 1 minute 45 seconds depending on microwave wattage.
  6. Rest and Serve: Carefully remove the mug and let it rest for 1 minute to allow residual heat to finish cooking and set the custard. Serve immediately with your favorite toppings like syrup, fruit, or powdered sugar.

Notes

  • Use slightly stale or thick-cut bread for best custard absorption without sogginess.
  • Adjust cooking time according to your microwave wattage and bread type to prevent overcooking.
  • You can substitute milk with any plant-based milk for a dairy-free version.
  • Sweetener can be varied—maple syrup, honey, or sugar all work well.
  • Letting the bread soak longer improves custard penetration for a richer texture.
  • Use a mug at least 12 ounces to avoid overflow during cooking.
