This Blueberry Lemon Crumb Cake recipe is a delightful twist on the classic blueberry crumb cake. The addition of lemon zest and juice gives the cake a bright, citrusy flavor that pairs perfectly with the sweet blueberries. The Thermomix makes it easy to mix the batter and crumb topping, and the cake bakes up perfectly every time. Serve it warm with a cup of tea for a lovely afternoon treat.
