Sponge cake
This classic sponge cake combines eggs, caster sugar, plain flour and butter into a light, airy bake. The Thermomix TM7 whisks the eggs to voluminous peaks and mixes the batter evenly, giving a fluffy texture that rises beautifully in the oven. Ideal as a base for birthday cakes, layered desserts or simply enjoyed with afternoon tea.
About this recipe
Sponge cake Thermomix TM7 recipes belong in every baker's repertoire, and this one delivers a feather-light crumb using nothing more than eggs, caster sugar, plain flour and butter. Searching for an easy dessert for the all-in-one kitchen machine often leads to complicated bakes, yet this sponge keeps things beautifully simple. The TM7 whisks whole eggs with homemade vanilla sugar until pale and thick — the crucial step that traps the air responsible for the cake's impressive rise. Because the mixing bowl blends the flour in gently and evenly, you avoid the overworking that makes sponges dense. Serve it plain with a dusting of icing sugar for afternoon tea, split and fill it with jam and whipped cream for birthdays, or use it as the foundation for a festive layered dessert. Greasing the springform tin properly and folding with confidence are the only skills you need.
Preparation tips
- Ensure the eggs and butter are at room temperature before you start, as cold eggs will not whisk to the volume needed for a light sponge and cold butter will not incorporate smoothly into the batter.
- Grease the springform tin thoroughly and consider lining the base with baking paper so the delicate sponge releases cleanly without tearing when you open the tin after baking.
- Test doneness by inserting a skewer into the centre of the cake; if it comes out clean, the sponge is ready. Leave it to cool in the tin for a few minutes before turning out onto a wire rack.
Recipe variations
- Citrus variation: add finely grated lemon or orange zest to the egg and caster sugar mixture for a fresh, fragrant sponge that pairs wonderfully with a citrus curd filling and a dollop of whipped cream.
- Festive chocolate version: replace a few tablespoons of the plain flour with cocoa powder and fill the cooled sponge with whipped cream and fresh berries for an impressive birthday celebration cake.
