Gluten free American-style Sponge Cake

this gluten free sponge cake makes a good base for decorating

The filling in the cake in this photo is Nestlé’s toffee spread which goes really well. I have also added tinned peach slices in light syrup over the toffee spread.

This sponge cake makes a good base for a celebration cake; it can be marzipanned, iced and decorated. The cake is easy to make, light, moist and delicious.

After you make this gluten free cake for the first time, I believe that you might never go back to making cakes which include rice flours, because that texture, flavour and the shelf life of this cake is far superior. But don’t take my word for it, try making the cake yourselves and let us know your thoughts!

Gluten free American-style Sponge Cake

Makes 1x15cm diam, cake


Tin size: 15cm diameter
Baking time: 35 to 45 minutes approx.
Oven temperature: 180ºC

125g of softened butter
185g of golden caster sugar
125g of Isabel’s all-purpose Cassava flour
40g cornflour
1 tsp of baking powder
2 Tbsp of milk
½ tsp of vanilla essence/extract
3 Large eggs yolks
3 egg whites whisked until stiff


Pre-heat the oven to 180ºC (350ºF/Gas Mark 4). Grease and line the baking tin with grease proof paper.
Place the sugar and butter in mixing bowl. Mix together and beat for 2-3 minutes until light and fluffy. Then add the egg yolks one by one and beat until all mixed.

Stir together the flours and baking powder. Then gradually add the flours to the sugar, butter and yolks mixture. Add the milk and beat well until the milk is fully incorporated to form a lump free batter.

Place the egg whites in a clean grease free bowl and whisk until stiff, but not dry.
Add one third of the egg whites to the cake mixture, and carefully fold in the egg white using a balloon whisk or metal spoon, cutting through and turning the mixture until all the egg whites have been incorporated. Repeat this process with the remaining egg whites.

Pour the mixture into the prepared greased and lined tin and gently level the top with a spatula.

Place the cake mixture in the centre of the pre-heated oven for 35 to 45 minutes. Test the cake by inserting a tooth pick at the centre. The cake should be golden brown and feel firm and springy when cooked. Loosen the edges with a palette knife and invert onto a cooling rack.

Carefully remove the lining paper, turn the cake the right way up and leave until cold.
