  • 110 g Unsweetened plant-based milk
  • 95 g Neutral-flavored oil
  • 2 tsp Apple cider vinegar Contributes to the cake's lightness.
  • ½ tsp Fine salt
  • 45 g Dutch-process cocoa powder (sifted if needed)
  • 1 tsp Baking powder
  • ½ tsp Baking soda
  • 190 g All-purpose flour

Mocha Glaze Ingredients

  • 100 g Powdered sugar

  • 14 g Melted plant-based butter
  • 1 tsp Instant espresso powder
  • 1–2 tbsp Unsweetened plant milk Adjust as needed for consistency.

Instructions
 

Preparation

  • Preheat the oven to 350°F (175°C) and prepare an 8×8-inch pan with oil or spray, then line with parchment leaving overhang for easy lifting.
  • In a large bowl, mix mashed bananas, sugar, plant milk, oil, vinegar, and salt until smooth and fully combined.
  • Whisk in cocoa powder until the mixture becomes uniform and glossy. Add baking powder and baking soda, then incorporate flour gradually until a thick batter forms without dry pockets.

Baking

  • Transfer the batter into the prepared pan, spread evenly, and gently tap to remove air bubbles.
  • Bake for 35–45 minutes until risen, set, and a toothpick comes out clean.
  • Let cool in the pan for about 15 minutes, then lift out using parchment and allow to cool completely on a rack.

Glazing

  • For the glaze, combine powdered sugar, cocoa, melted butter, espresso powder, salt, and milk. Whisk until smooth and pourable but still thick.
  • Pour the glaze over the cooled cake, spread lightly if needed, and let it set for about 15 minutes before slicing.

Notes

Store covered loosely at room temperature for up to 3 days. The cake gets softer over time due to the glaze. For longer storage, wrap tightly and refrigerate to keep fresh for about a week.
