Blueberry and Lemon Spumble
Blueberry and Lemon Spumble is a wholesome breakfast or snack crumble where juicy blueberries and zesty lemon meet toasted hazelnuts, rolled oats and pumpkin seeds. The Thermomix weighs, grinds and mixes everything in one bowl, then heats the honey-sweetened fruit to a bubbling base. A crunchy oat-nut topping makes it nutritious comfort food.
About this recipe
Blueberry and Lemon Spumble in the Thermomix TM7 is the kind of quick dessert recipe that feels indulgent yet wholesome, combining jammy blueberries and sharp lemon under a crunchy canopy of oats, hazelnuts and pumpkin seeds. Searching for healthy dessert ideas with your all-in-one kitchen machine usually leads to compromises, but this spumble — a spoonable cousin of the crumble — delivers real texture and bright flavour with almost no hands-on work. The TM7 grinds the hazelnuts to exactly the right coarse crumb, mixes the oat topping evenly with honey and a pinch of sea salt, then gently heats the blueberries, lemon juice and water until they burst into a glossy, sauce-like base. A sprinkle of chia seeds thickens the fruit naturally if you like a set consistency. Serve it warm as a weeknight dessert, cold from the fridge for breakfast with yogurt, or pack it into lunchboxes — one bowl, one blade, minimal washing up.
Preparation tips
- Toast the hazelnuts in a dry pan or on a tray before grinding them in the Thermomix; this deepens their flavour and stops the oat topping from tasting flat against the sharp lemon and blueberry base.
- Keep a few whole blueberries aside and stir them in after heating so the spumble has bursts of fresh fruit alongside the sauce-like cooked layer, adding contrast in every spoonful.
- The spumble keeps well covered in the fridge for several days; reheat portions gently or serve chilled over yogurt at breakfast. Swap runny honey for maple syrup if you prefer a plant-based sweetener.
Recipe variations
- Make it gluten-free by using certified gluten-free rolled oats and replacing any wheat-based ingredients in the topping; the hazelnut and pumpkin seed crunch works beautifully with buckwheat flakes too.
- For a festive winter version, swap the blueberries for a mix of frozen forest fruits, add a pinch of cinnamon and grated ginger to the lemon base, and scatter the topping with flaked almonds before serving warm.
