Ingredients:
3 eggs
4. Add sifted cake flour and cocoa powder, mix well, then add corn oil and mix evenly.
5. Fill the cake batter into paper cups, about 80% full. 6. Tap the cups lightly several times to remove excess air bubbles, then add an appropriate amount of dried cranberries. 7. Place in the preheated oven, lower-middle rack, at 140°C, and bake for about one hour. 8. The cake is ready. Low-temperature slow baking results in a very soft and fluffy cake.
