Step 1

Drizzle the oil into a tall straight mug, about 3.5 inches wide and 5 inches tall. Brush the oil around the edges to grease the mug.

Step 2

Place the eggs, almond flour, baking powder, and salt in the mug. Whisk with a fork until very smooth. Tap the mug on the counter to remove air pockets.

Step 3

Microwave on high heat for 3 minutes. Shake the bread loaf out of the mug. Slice with a serrated knife and serve.

Step 4

Wrap well and store in the refrigerator.
