A quick and easy keto-friendly sandwich bread recipe that is fluffy, low-carb, and ready in just 90 seconds using a microwave.

Ingredients

Scale
  • 1/4 cup (28g) almond flour
  • 1/4 teaspoon baking powder
  • 1 large egg, room temperature
  • 2 tablespoons (30ml) unsweetened almond milk
  • Pinch of salt
  • 1/2 teaspoon apple cider vinegar
  • 1 teaspoon melted butter or coconut oil (optional)

Instructions

  1. Measure out 1/4 cup (28g) almond flour, 1/4 teaspoon baking powder, a pinch of salt, and prepare your wet ingredients: 1 large egg, 2 tablespoons (30ml) unsweetened almond milk, 1/2 teaspoon apple cider vinegar, and 1 teaspoon melted butter or coconut oil.
  2. In your microwave-safe mug or bowl, combine the almond flour, baking powder, and salt. Use a fork or small whisk to break up any lumps.
  3. Crack the egg into the dry mix, pour in almond milk, apple cider vinegar, and melted butter. Stir vigorously until you get a smooth, thick batter with no visible lumps. The batter should be pourable but thick—if it’s too runny, add a pinch more almond flour.
  4. Place the mug in the microwave and cook on high for 90 seconds. Adjust time by 5-10 seconds if needed based on your microwave strength.
  5. Check doneness by ensuring the bread rises nicely and feels springy to the touch. Insert a toothpick in the center; it should come out mostly clean.
  6. Let the bread sit for 2 minutes to firm up. Then, carefully run a knife around the edges and tip it out onto a plate.
  7. Slice with a serrated knife and serve fresh, or toast and store for later use.

Notes

Use finely ground almond flour for a softer crumb. Adjust microwave time based on your appliance’s power. Grease the mug lightly if it’s your first time to prevent sticking. For a fluffier bread, whisk egg whites separately and fold in gently. Variations include adding cheese, herbs, or using coconut flour with adjusted liquid and egg amounts. Oven baking at 350°F for 10-12 minutes is an alternative method.
