Preheat the oven to 160 degrees. Then simply put all the dry ingredients in a bowl and stir a few times.
Then add the liquid ingredients and mix everything together. Add a little more oat milk or flour if the dough is too liquid/solid.
Shape the dough into 8-10 equal-sized balls, using an ice cream scoop if necessary, and place them on a baking tray lined with baking paper. Flatten them a little to create the desired biscuit shape.
Bake the biscuits for 10-14 minutes in a convection oven at 160 degrees. After this time, they are usually already cooked through and still nice and soft.
Let the biscuits cool as soon as they are ready. Then dip them in some oat milk and put the cinnamon-sugar mixture on the biscuits.
Enjoy it! It's also very tasty to dunk them in oat milk :)
