This cake works because spelt flour has a lower gluten tension than regular wheat, so the crumb stays soft without any risk of toughening – even if you overmix slightly.
Fresh or frozen blueberries both work here. Frozen ones sink a little less during baking, which gives you a more even distribution through the slice.
Lemon zest carries more fragrance than juice alone. I use the zest of a full lemon in the batter and a light lemon drizzle on top to keep the citrus flavour present in every bite.
The batter comes together in one bowl with a wooden spoon. No stand mixer, no creaming step that takes ten minutes.
Why You’ll Love This Recipe
- One bowl, minimal washing up after baking.
- Spelt flour gives a nutty, tender crumb naturally.
- Lemon zest keeps each slice bright, not bland.
- Stays moist for two days without drying out.

Ingredient Notes
- Wholegrain spelt flour: Spelt flour absorbs liquid slightly faster than plain wheat flour, so don’t leave the batter sitting long before baking. White spelt flour works too and gives a lighter texture.
- Blueberries: Fresh blueberries hold their shape well. If using frozen, add them straight from the freezer without thawing to reduce excess moisture in the batter.
- Lemon zest: Use an unwaxed lemon and zest it finely. The zest carries the fragrance; the juice alone won’t give the same result.
- Plain yogurt: Full-fat Greek yogurt or plain yogurt both work. The acidity reacts with the baking soda to help the cake rise evenly. Dairy-free coconut yogurt is a reliable swap.
- Light olive oil: Oil rather than butter keeps the crumb moist and the method simple. A neutral-flavoured sunflower oil is also fine.
- Baking powder: Check it’s fresh – spelt batters are denser than standard wheat, so a spent baking powder will leave the cake flat. Replace if it’s been open more than six months.

Spelt Blueberry Lemon Breakfast Cake
Description
Spelt flour keeps the crumb tender without heaviness, while lemon zest and fresh blueberries give each slice clean, bright flavour. It bakes in one bowl and holds well for two days.
Ingredients
Cake batter
Lemon drizzle (optional)
Instructions
Prepare
- Heat the oven to 180 C / 355 F. Grease a 9-inch round cake tin and line the base with baking paper.
- Toss the blueberries with 1 tsp of spelt flour in a small bowl and set aside.
Mix the batter
- In a large mixing bowl, whisk together the spelt flour, baking powder, baking soda, salt, and sugar until combined.
- Rub the lemon zest into the sugar with your fingertips for about 30 seconds until the mixture smells fragrant and looks slightly damp.
- Add the eggs, yogurt, oil, lemon juice, and vanilla extract to the bowl. Stir with a wooden spoon until just combined - stop as soon as no dry flour streaks remain.
- Fold in the flour-coated blueberries gently with three or four strokes, keeping them as whole as possible.
Bake
- Pour the batter into the prepared tin and smooth the top lightly with the back of a spoon.
- Bake on the centre shelf for 32 to 35 minutes, until the top is set and lightly golden and a skewer inserted into the centre comes out clean.
- Remove from the oven and cool in the tin for 10 minutes, then transfer to a wire rack to cool for at least 15 minutes before slicing.
Lemon drizzle (optional)
- Whisk the sifted icing sugar and lemon juice together until smooth and pourable. Drizzle over the warm cake and let it set for 5 minutes before serving.

Note
Additional Notes
- Add blueberries frozen if using from frozen - thawed berries make the batter watery.
- Bake immediately after mixing - spelt flour absorbs liquid fast and the batter thickens.
- Do not open the oven before 25 minutes or the cake may sink in the centre.
- Rest on a wire rack for at least 15 minutes before slicing for a clean cut.
- Use the zest of a full lemon for clear citrus flavour - half a lemon is not enough.
