Its made from ground walnuts, so can easily be made at home as well by pulsing dry toasted walnuts in a food processor. You would need to be a bit careful with this though as going too far would give you walnut butter instead.

Oatmeal: Using rolled oats in this banana bread not only lets the bread be gluten-free, but also makes it a whole lot heartier. It also gives the loaf more volume without as high a calorie bump as regular flour would.

Oat flour: The oat flour in addition to the walnut/almond flour replaces the whole wheat or all purpose flour that a banana bread otherwise needs.

You can also substitute just rolled oats for oat flour here. If you don’t have any, pulse about ¾ cup of rolled oats in a food processor until it gets a flour consistency.

Putting together the instant coffee, rolled oats, oat flour, almond/walnut flour and chopped nuts, you get a delicious coffee infused oatmeal banana bread that makes just the perfect healthy breakfast loaf!

Some tips to make this loaf?

Toast the rolled oats in the oven for about 10 minutes (and let it cool) before baking it into the bread so that it does not absorb too much moisture.
Whisk all the wet ingredients separately and the dry ingredients separately first.
Make sure you combine the oat flour, walnut flour/almond flour and rolled oats evenly so that everything blends well and holds together when the banana bread bakes.
Add the dry to the wet and then fold or stir the mix until it’s uniform. It shouldn’t take too long since all the dry ingredients are absorbent.
Let the batter rest for about 5-7 minutes so that the oatmeal has a but of time to soak up some of the liquid and the batter thickens a little.
Use a foil tent part-way through baking so the top does not burn.
To know when it’s done, make sure the tester inserted comes out without any batter. The top of the loaf might darken, but it does not mean it is done.

Does this walnut oatmeal espresso banana bread keep?

Yes! Let the loaf cool completely first and the put it away for later.
