Step 1

Preheat oven to 375F (190C). Line a baking sheet with parchment paper.

Step 2

In a medium bowl, combine the oats and water. Let stand for 10 to 15 minutes to soften. Vigorously stir for 30 to 60 seconds to break down the oats. Add the almond flour, baking powder, and (optional) salt, stirring to combine.

Step 3

Transfer dough to center of prepared baking sheet. Using fingertips, press into an even 10 x 8-inch (25 x 20 cm) rectangle. Dimple the surface of dough (slightly) with fingertips.

Step 4

Bake in the preheated oven for 22 to 25 minutes until light golden brown at edges, the center is set, and the surface appears dry.

Step 5

Using the parchment paper, lift the bread off of the baking sheet, and then slide off of the parchment paper onto a cooling rack. Serve warm or cool completely.
