Units Scale
  • 8 cups of cubed Italian bread (about 1/2 loaf)
  • 1 cup Milk
  • 3 Eggs
  • 1 Teaspoon Vanilla (optional)
  • Pinch of salt
  • 1/4 cup Monk Fruit
  • 1/4 cup Peanut Butter Powder
  • 1/2 cup Fresh Blueberries


  1. Cut  bread into 1 inch cubes and place in a large bowl
  2. In a measuring cup with a spout, whisk together the milk, eggs, salt, and vanilla (if using)
  3. Pour the egg mixture over the bread cubes, stir with a wooden spoon, and let the bread soak up the custard for 20 minutes
  4. While the bread is absorbing the custard, pre-heat the oven to 400 degrees f and grease an 8x8 inch baking dish with cooking spray. You can also mix the monk fruit and peanut butter powder together in a small bowl and set that aside.
  5. After 20 minutes, put half of the soaked bread cubes on the bottom of the dish, making sure they're evenly spread out. Sprinkle over 1/4 cup of blueberries and half of the monk fruit/ peanut butter mixture. Repeat with the rest of the bread cubes, 1/4 cup of blueberries, and the last of the sweet peanut butter topping
  6. Place the whole casserole into the pre-heated oven and bake for 35-40 minutes until the top pieces are a dark golden brown. (If it's getting too dark, but there's still baking time left, you can cover the top with aluminum foil and continue baking)
  7. Let sit 10-15 minutes before slicing and serving


  • Calories calculated are an estimate
  • Cut the bread into even size cubes so they bake evenly
  • You can prepare this the night before and just bake it in the morning
  • Cover the top with foil if  it's getting too dark for you
  • You can use almond butter powder in place of the peanut butter powder if you have a peanut allergy
  • Soy milk has the same amount of protein as whole milk- making is a great dairy free option
  • Store leftovers in an airtight container in the fridge for up to 5 days
  • Reheat in the oven or a pan with a lid
