Once cooled, very carefully cut each cake in half – the outside edge can be a bit crumbly so use a very sharp knife and a gentle hand.
for the filling:
Combine the heavy cream, erythritol and vanilla in a large mixing bowl and using an electric hand mixer, beat until thick and creamy.
putting it all together:
Complete each layer by spreading a layer of whipped cream on top of a cake layer, sprinkling some strawberries on top of the whipped cream and topping with another layer of cake. Repeat until you have used all for layer of cake.
