Ingredients

For the Casserole:

  • 6 slices keto sandwich bread (dried or toasted)

  • 5 large eggs

  • 1/2 cup heavy cream

  • 1/4 cup unsweetened almond milk

  • 2 tsp ground cinnamon

  • 1 tsp vanilla extract

  • 3 tbsp powdered erythritol

  • Pinch of salt

  • 2 tbsp melted butter

For the Cinnamon Swirl:

  • 2 tbsp erythritol

  • 1 tsp cinnamon

For the Icing (optional):

  • 3 tbsp cream cheese, softened

  • 1 tbsp heavy cream

  • 1 tbsp powdered sweetener

  • 1/2 tsp vanilla extract

Instructions

  1. Cut keto bread into cubes or strips and toast if fresh.

  2. In a bowl, whisk eggs, cream, almond milk, vanilla, cinnamon, sweetener, and salt.

  3. Add bread to the mix and let soak for 5–10 minutes.

  4. In a small bowl, mix cinnamon swirl ingredients into a smooth paste.

  5. Layer soaked bread into a greased baking dish. Drop spoonfuls of the swirl mix across the top. Drizzle with melted butter.

  6. Cover and refrigerate overnight (or bake immediately if needed).

  7. Bake at 350°F for 35–45 minutes until golden.

  8. While it bakes, mix icing ingredients until smooth.

  9. Drizzle icing over hot casserole and serve.

Notes

  • Use any low-carb bread: sandwich, white, or even homemade keto breads.

  • Best flavor comes from letting it chill overnight.

  • Add chopped pecans or sugar-free chocolate chips for variety.

  • Store leftovers in fridge up to 5 days or freeze in portions.
