Before starting with the banana bread itself, pre-heat your oven to 180 degrees & prepare your loaf tin with baking paper.
Start with adding the 6 bananas to a large bowl & break them into smalelr pieces with your hands. Next, mash them with a fork until creamy. This step is really important, as the banana is what makes the bread stick together. You could use a mixer, but it is THAT much better when using a fork & mashing them slowlely.
Next, add the maple syrup & almond milk & mix with a spatula. Again, using a mixer is possible, but the results are better doing it by hand.
Last, but not least, add all the remaining ingredients, apart from the chopped walnuts. Mix the dough until well combined & quite goeoey. I hate to repeat myself, but if you still can, mix it by hand, please.
As a last step fold in the chopped walnuts & transfer everything to your prepared loaf tin.
Top the banana bread mass with the chopped nuts & the banana. Make sure to press the banana slightly into the dough, so it doesn't burn.
Bake for aroung 60 minutes. Take the banana bread out of the loaf tin immediatly, as to allow any excess moisture to evaporate.
