Caster Sugar - this sugar is very important for the texture, so the best US substitute is Extra/Super Fine sugar. Or you can lightly process granulated sugar. See my sugar comparison image before the step-by-step instructions above.
Flavourings - Vanilla extract is better than flavouring/essence. It is costly but, so it is much better making your own vanilla extract. Or, you can make alcohol-free extracts to save even more. I also add a touch of almond extract to enhance flavour.
Flour - for the gluten-free flour I have used and recommend Doves Farm gluten-free range Freee Foods. You can use their Plain flour or their Self-raising flour. For their Plain flour (or any other All Purpose gluten-free flour), remember to add the 2 amounts of baking powder listed. And if making for someone who needs gluten-free, make sure the baking powder is gluten-free too. I use Dr Oetker. You can make a regular, gluten cake by using normal self-raising or plain (A.P.) flour.
Xanthan Gum - this is the binding agent in gluten-free baking. There is some in the gluten-free flour, but a little more is needed for this cake. Again I use Freee Foods brand, that can be easily found in larger supermarkets, (with the gluten-free flour). Alternative is Guar Gum.
Cream Filling - whipped cream (from double/heavy/whipping cream) is traditional to a Victoria Sandwich cake. But I have also tried with clotted cream. This saves you whipping & piping the cream and sets better.
Berry Filling - use fresh strawberries, raspberries or blueberries as the perfect accompaniment to cream layer cake.
Bundt Tin - as this is for a small basket air fryer, the cake is baked in a bundt tin that is a bit smaller than a regular ‘Kugelhopf Pan’, measuring 6.5″ (17cm) wide. A similar standard pan is about 8.6″ (22cm) wide. You can read more and learn how to make in the bigger tin, in the equipment section above.
Air Fryer Or Oven? - this recipe is for a small basket air fryer, 3.5 litre, about 3.7 quarts but easily can be made in bigger open-front air fryer or regular oven.
Recipe Yield - using the same size and shape tin, this recipe yields 8 slices. They look small but are deep layers and with a nice amount of filling.
