Ingredients and substitutions for Czech Bublanina
- Butter: Butter must be room temperature here to create the nice and fluffy base of the sponge cake which allows more air to be whipped up and help the sugar begin dissolving. Unsalted was used as this is fresher than salted, however, you could absolutely use salted butter here.
- Sugar: Superfine or caster sugar gives our cake it’s sweetness without overly flavoring the cake allowing the vanilla to shine. You could substitute with raw sugar or half and half with brown sugar, though your cake would have slightly more caramel flavor. Icing or confectioner’s sugar is best here because it dissolves into the egg whites due to it’s incredibly fine texture.
- Plain flour: You don't need much and don't want to overwork the batter so you have a nice fine sponge texture.
- Baking powder: This helps our cake rise so to create the nice light crumb and avoid a dense cake. Baking powder can expire, so it's best to check the best before date, particularly if yours has been open for some time.
- Eggs: The eggs need to be room temperature here to bind with the butter and sugar as room temperature eggs allow more air into them giving our sponge that nice and light texture.
- Vanilla extract: Vanilla extract acts as a flavor enhancer in the cake, without it we wouldn't have depth of flavor when we bite into the cake.
- Cherries: Fresh sweet cherries were used here, though sour cherries, blueberries or even strawberries are all commonly found in Bublanina’s. You can replace the fresh fruit with jarred or canned, though you’ll need to fully drain before adding to the cake. Frozen would also work, though it best to defrost and drain before adding to the cake, otherwise the result might be a soggy cake.
