Start by preheating your oven to 180 C / 350F. This is important as it ensures your cookies bake evenly. While the oven is warming up, line a cookie sheet with parchment paper. This will prevent sticking and make cleanup a breeze.
Next, take your ripe banana and mash it using a fork in a mixing bowl. You want it to be smooth without any large chunks. The more ripe the banana, the sweeter your cookies will be, so don’t shy away from those overripe ones!
In the same bowl, add the almond flour, almond butter, butter, egg, golden erythritol, cinnamon, and baking powder. Using an electric mixer, blend these ingredients together until the mixture is smooth and well combined. It should have a creamy texture.
Once combined, use a tablespoon to scoop out the cookie batter and dollop it onto the prepared cookie sheet. Aim for about 1 tablespoon per cookie, spacing them out adequately. This is important as the batter will spread while baking.
If you’re using crushed walnuts, sprinkle them generously on top of each cookie. This adds a wonderful crunch and a nutty flavor that pairs beautifully with the sweetness of the banana.
Now, pop the cookie sheet into the oven and bake for 10 to 12 minutes. Keep an eye on them; you want the edges to be very lightly browned. The center should still look slightly soft.
After baking, remove the cookies from the oven, but resist the urge to touch them right away! Let them cool on the cookie sheet for several minutes, as they are very soft when they first come out.
Once they’ve cooled a bit, transfer the cookies to a wire rack to cool completely. This final cooling step is crucial, as they will firm up as they cool.
