So,let's see how to make this easy Blueberry Walnut Sponge Cake 

For this recipe i used my basic sponge cake recipe with little adjustments and even the batter it looks quite soft it holds almost any fruit on top.It's great with berries and equally delicious with stone fruit,apples and pears can be used as well.If you're using small berries like blueberry,raspberry or blackberry you can use them whole,larger pieces of fruit like peaches,plums,nectarines,apricots should be cut into wedges or diced into chunks-pear and apples,par exemple.
As this recipe is written,the cake doesn't use any leavening agents and it gets its rise from the air whipped into the eggs,that's why it has a spongy texture and that's why it's called sponge cake!
The recipe steps are straightforward and the batter comes together quickly.Egg whites are beaten with sugar until stiff peaks form then egg yolks are added one at a time while whisking constantly.It will take approx. 4 minutes until the mixture triples in volume then with the speed mixer on low the milk and the oil are added to the batter and finally flour is folded in gradually and in several additions.


For a GF version you can swap all purpose flour for rice flour,i highly recommend you using rice flour because i tried it before for a GF recipe and i loved how it turned out.Gluten free cakes often have a bad reputation for being too dry but the addition of milk and oil will keep the crumb moist.
