Step 1

You can watch the video in the post for visual instructions.

Step 2

First, preheat the oven to 355 °F/180 °C and line a 7x7-inch square baking dish (18 cm) or 9x6-inch baking pan with parchment paper.You could use an 8x8 pan, but the bars will be thinner. For a much larger pan, it's best to double the recipe.

Step 3

Then, process all the dough ingredients in a food processor until dough-like.

Step 4

Press ¾ of the dough into the prepared pan, using the bottom of a flat glass to help make a single even layer.

Step 5

Then, rinse the food processor and process the chocolate layer ingredients until smooth and creamy.

Step 6

Pour the chocolate layer over the oat base, and then crumble and sprinkle the remaining oat mixture over the top.

Step 7

Crumble the remaining 1/4 dough on top of the chocolate layer.

Step 8

Bake for 25-30 minutes, until golden brown on top, then leave the banana breakfast bars to cool completely (they will firm up/set as they cool). Finally, cut them into bars, and enjoy!

Step 9

You can optionally drizzle the chocolate oat bars with a simple homemade icing (regular or sugar-free), homemade vegan Nutella, or another nut/seed butter.
