For sweet bean paste, put canned beans and liquid into pan over medium heat. Add Stevia gradually while stirring. Cook over low heat until the liquid has almost evaporated and the beans have become mushy. Remove from heat and let cool.
Mix Stevia, eggs, and syrup in a bowl, blend until sugar has dissolved, then add the flour to make a smooth batter. Cover and leave for 20 minutes.
Mix together baking soda and water then mix into the batter.
Heat oil in a small pan until hot, reduce to medium heat and ladle some batter into the center. Make pancakes to desired size. If desired, you can make larger pancakes and fold the red bean paste in the middle to make half circles.
Cook for about 2-3 minutes on each side. And set aside.
Take one pancake and spread about 2 tablespoons of the bean paste in the middle leaving about ½ inch around the edge. Then pipe in one teaspoon of whipped cream and then cover with another pancake. Serve warm or cold.
