Start by preheating your oven to 350°F (175°C) and prepare your cake pan by greasing it or lining it with parchment paper.
In a spacious bowl, mix together the oat flour, almond flour, baking powder, baking soda, salt, and cinnamon. Give it a good whisk so everything is evenly mixed.
In another bowl, whisk together the plant-based milk, maple syrup, melted coconut oil, flax egg, vanilla, and applesauce until smooth.
Pour the wet mixture into the dry ingredients and gently stir until they’re just combined. Be careful not to overmix, as the batter should be slightly thick but easy to pour.
If you want to add a little extra, fold in some raisins, nuts, or chocolate chips for an added crunch or flavor.
Pour the batter into the prepared pan, smoothing it out so it’s even.
Bake for 30 minutes, or until the top turns golden and a toothpick inserted comes out clean.
Allow the cake to rest in the pan for 10 minutes before transferring it to a wire rack to cool completely.
Once cooled, slice and enjoy! For a special touch, top with maple syrup, vegan yogurt, or fresh berries.
