Orange Sponge Cupcake

I have always loved sponge cupcakes, especially orange flavored ones. You really could flavor this in any way you like it! i think i have a soft spot for anything cottony soft, light & fluffy. Something that is not too heavy for a tea time snack.

The trick to getting a really fine texture to the cake is to beat the egg whites at a really slow speed! Learned something new huh 😛

(adapted from Vanessa Tay)


  • 5 egg yolks
  • 100g cake flour
  • 50g corn oil or melted butter (I used melted butter)
  • 60g orange juice
  • Zest of 1 orange
  • 5 egg whites
  • 70g sugar
  • 1/4 tsp cream of tartar


  1. Preheat the oven to 180C. Line the moulds with parchment paper. You may use muffin trays. I used paper cups instead, by lining the paper cups with the parchment paper and then placed the cups in the holes of the muffin tray.
  2. Melt butter in a microwave oven or heat over boiling water in a bowl. Lightly beat egg yolks with fork.
  3. Zest 1 orange and add into orange juice. Add this to the melted butter.
  4. Sift in cake flour to the orange juice mixture in  a few additions, alternating with egg yolk and flour. Start and end with flour.
  5. Use an electrical mixer to beat egg whites for 3 minutes, then add cream of tartar and blend again. Pour sugar in the egg whites and blend until very stiff peaks form.
  6. Fold egg whites into the flour mixture gently with a rubber spatula just until all ingredients are incorporated. Do not stir or beat. For a better result, fold in egg whites with small amount at a time for 3 times.
  7. Pour batter into cup cake molds that are already lined with baking paper. Bake at 180C for 25 to 30 minutes. Check with a toothpick to see if the cakes are done. If the toothpick comes out of the cake clean, then they’re ready. Allow the cakes to cool for a minute or two in the pan, then transfer to a wire rack to cool completely.
