Preheat oven to 176C | 350F. Grease a square 8-8-inch baking tray with cooking oil spray, and wipe over with a paper towel.
In a bowl, whisk brown sugar, natural sweetener, butter, and apple sauce until creamy. Add egg and vanilla extract, and whisk again until light and creamy.
In a smaller bowl, combine plain flour, baking powder, ground cinnamon, and salt. Gradually beat in the dry ingredients.
Pour in the almond milk into the batter and mix well. Do not overbeat the batter.
Pour batter into prepared baking tray and sprinkle with Cinnamon sugar.
Bake until golden, about 20 to 25 minutes, or until a toothpick inserted into the centre comes out clean.
Cool completely before spreading with melted chocolate of choice or a clean chocolate sauce.
To make your own chocolate sauce, combine ingredients until sauce is desired consistency.
Enjoy!
