In a blender combine all the ingredients and blend on high until smooth and creamy, about 30 seconds.
Step 2Prepare a steamer basket and bring the water to a simmer over medium heat. Remove the lid off the steamer and gently place 4 cupcake-lined ramekins onto the steamer basket. Carefully pour the batter into each ramekin, filling to the top. Steam for 15 minutes on medium-low heat, or until a toothpick comes out clean when inserted. Transfer the cake out of the steamer basket and enjoy warm with a cup of tea.
