About this recipe

Better banana cake Thermomix TM7 is the ultimate way to transform speckled, overripe bananas into a moist and aromatic dessert that everyone loves. If you have been searching for banana cake recipes for your all-in-one kitchen machine, this version delivers a tender crumb thanks to self raising flour, bicarbonate of soda and a generous splash of milk, all blended evenly in seconds. The TM7 mixing bowl becomes your single workspace: the integrated scale weighs the raw sugar and flour to the gram, the mixer folds the mashed bananas into a lump-free batter, and the whipping function turns butter and icing sugar into a silky frosting without a single hand whisk. Served warm with coffee at teatime or packed into lunchboxes, this cake also shines at birthdays and weekend brunches. A touch of natural vanilla extract rounds out the sweet caramel notes of the banana, making every slice taste homemade and comforting.

Preparation tips

  • Use bananas that are heavily speckled or almost black, as their natural sweetness and moisture give the cake its characteristic soft crumb and deep caramel flavour without needing extra sugar.
  • Mash the bananas and mix the batter only until just combined; overmixing the self raising flour develops gluten and produces a dense, rubbery cake instead of a tender, airy slice.
  • For the buttercream, make sure the butter and milk are at room temperature before whipping with the icing sugar, and apply it only once the cake is completely cool to prevent it from melting and sliding off.
  • Store leftover cake in an airtight container and gently warm individual slices before serving to revive the banana aroma and soften the frosting.
  • This cake freezes beautifully without the icing: wrap cooled slices individually so children can grab a ready-made snack, then thaw and frost only what you need.

Recipe variations

  • Nutty version: fold roughly chopped walnuts or pecans through the banana batter just before baking, and toast a handful to scatter over the buttercream for extra crunch and a richer flavour.
  • Chocolate variation: add dark chocolate chunks to the batter and swap a spoonful of the icing sugar for cocoa powder in the buttercream, creating a classic banana-chocolate combination children adore.
  • Festive spin: spice the batter with cinnamon and a pinch of nutmeg, then top with a cream cheese style buttercream and caramelised banana slices for a celebration-worthy dessert.
