Step 1

Preheat the oven to 375°F.

Step 2

Butter a standard-sized bread pan until well-covered.

Step 3

Separate the egg whites and yolks into two separate bowls, placing the egg whites in the larger bowl.

Step 4

Add the cream of tartar into the egg whites and whisk until sturdy peaks form when you remove the mixer from the bowl.*

Step 5

In the bowl with the egg yolks, add in the butter, sour cream and mix until combined.

Step 6

Mix in the almond flour, salt, baking powder (and stevia, if using) until just combined.

Step 7

Using a soft mixing spatula, gently fold the egg whites into the almond flour mixture in three to four separate batches, being careful not to over mix.**

Step 8

Pour the mixture into the buttered bread pan, and bake on the middle rack for 30-35 minutes, until the top has browned and the mixture is set in the middle.

Step 9

Let cool and slice into individual bread slices for your use.
