There are a few recipes out there for this "microwave sponge", but the issue is that it calls for a special piece of equipment, a siphon or cream whipper. While there are many uses and recipes for a cream whipper, the reality is that most people don't have this piece of equipment at home or make the quantities to justify having one.

The good news is that you can make a microwave sponge without a siphon or cream whipper. It takes just a little more time and patience, but it results in a sponge that is just as light and tasty for your plated desserts.

This is a recipe for a pistachio microwave sponge that has a soft texture and a light and clean flavour. The pistachio paste can be substituted for any other nut paste such as hazelnut.


  • 2 eggs
  • 1 egg white
  • 30g sugar
  • 20g pistachio paste (or any other nut paste)
  • 10g sifted flour


  1. Place all the ingredients into a stand mixer with the whisk attachment. Mix on a medium speed for about 5 minutes until all ingredients are incorporated and frothy.
  2. Turn up the speed to high and whisk for 15 minutes until light and frothy.
  3. Cut some slits the bottom of a paper cup. I usually cut an 'X' in the centre and then cut 4 slits around the edge.
  4. Carefully ladle 30g of mixture into the cup, being careful not to deflate the mixture.
  5. Microwave for 45 seconds. It should double in size.
  6. Once cooked in the microwave, allow to cool completely upside down on a cooling rack or off the edge of the bench. We turn it upside down to prevent the sponge from collapsing.
  7. Once completely cooled, run a knife around the edge of the sponge and tip it out. If the sponge is stuck, you can cut the cup away.
  8. Break carefully into smaller pieces, being careful not to squash the sponge.


Can I use a hand blender instead of a stand mixer?

You can use a hand blender to whip the mixture however, it takes a long time (~20 minutes) for the foam to form. But if you have the patience and endurance, go for it!

How do I store the sponge?

The best way to store the sponge is to wrap the sponge in plastic wrap after it has fully cooled and demoulded from the cup but before it is broken into smaller pieces. Store in a dark place at room temperature. Storing the sponge unwrapped or in the fridge could result in a dry sponge.
