Preheat oven to 175°C (fan-forced). Blend black beans, eggs, coconut sugar, almond butter, coffee & vanilla for 3 mins until smooth. Pulse in cocoa, baking powder & baking soda until just combined.
Bake at 175°C in a lightly greased 25 × 25 cm baking dish for 25-30 mins, or until a toothpick comes out clean. Cool.
Whisk almond milk + cocoa, poke holes in cake and pour over to absorb and keep cake moist.
Blend sweet potato, cocoa, maple syrup, almond milk & vanilla until very smooth. Add a little more milk if needed. Spread over cake.
Gently melt the choc hazelnut spread and chocolate chips in the microwave (10-20 seconds), stirring until smooth. Mix through the crushed bran flakes well, then sprinkle evenly over the cake.
Refrigerate for at least 1 hour to set. Slice and enjoy. Store in the fridge for up to 4–5 days.
