Why You’ll Love This Lemon Blueberry Streusel Muffins
- Entirely mixed in one bowl — no need to drag out the stand mixer or a separate bowl for dry ingredients, so washing up is minimal.
- The streusel topping bakes into a crunchy, golden lid that contrasts beautifully with the soft, fruity centre beneath.
- Fresh or frozen blueberries work equally well, meaning you can make these year-round without hunting for seasonal fruit.
- My kids absolutely devour this every time I make it, and I love that I can sneak a portion of Greek yoghurt into the batter for extra moisture and a touch of protein.
- These muffins keep beautifully for three days at room temperature or can be frozen for up to two months, making them a brilliant make-ahead option for busy mornings.
Ingredients You’ll Need
- 250g plain flour
- 150g caster sugar
- 2 teaspoons baking powder
- ½ teaspoon bicarbonate of soda
- ¼ teaspoon fine sea salt
- 120ml vegetable oil
- 120ml full-fat Greek yoghurt
- 2 large eggs, at room temperature
- 1 tablespoon lemon zest (from about 2 lemons)
- 2 tablespoons fresh lemon juice
- 1 teaspoon vanilla extract
- 200g fresh or frozen blueberries (do not thaw if frozen)
- For the streusel: 50g plain flour, 40g unsalted butter (cold, cubed), 40g light brown sugar, ½ teaspoon ground cinnamon
Tip: If you are using frozen blueberries, toss them in 1 tablespoon of the measured flour before folding them into the batter — this stops them sinking to the bottom of the muffin cases during baking.
How to Make Lemon Blueberry Streusel Muffins
- Preheat your oven to 200°C (180°C fan) and line a 12-hole muffin tin with paper cases. The cases will feel flimsy and light in your hand, but they hold their shape once filled.
- In a large mixing bowl, whisk together the flour, caster sugar, baking powder, bicarbonate of soda and salt. The mixture should look pale and powdery, with no lumps visible when you lift the whisk.
- Make a well in the centre of the dry ingredients and pour in the vegetable oil, Greek yoghurt, eggs, lemon zest, lemon juice and vanilla extract. Stir gently with a wooden spoon until just combined — you want a thick, bumpy batter that smells sharply of lemon. Stop stirring the moment you no longer see streaks of flour; overmixing will make the muffins tough.
- Fold in the blueberries with a silicone spatula, using no more than ten turns. You should see purple streaks bleeding into the batter, and the berries will be evenly distributed but not crushed.
- For the streusel, rub the cold butter cubes into the flour, brown sugar and cinnamon using your fingertips until the mixture resembles rough breadcrumbs. When you squeeze a handful, it should clump together briefly before falling apart again.
- Divide the muffin batter evenly among the 12 paper cases — each case should be about three-quarters full. The batter will feel thick and slightly sticky, almost like a soft cookie dough.
- Sprinkle the streusel topping generously over each muffin, pressing it down ever so lightly with your fingers so it sticks to the batter. You should see a thick, crumbly layer covering the surface.
- Bake for 18-20 minutes, rotating the tin halfway through. The muffins are ready when the tops are deep golden brown, the streusel looks crunchy and set, and a skewer inserted into the centre of a muffin comes out with just a few moist crumbs attached — no wet batter.
- Let the muffins cool in the tin for 5 minutes — you will hear a faint crackling sound as the sugar in the streusel sets — then transfer them to a wire rack to cool completely. The tops should feel firm but give slightly when pressed.
Tips From My Kitchen
- Use room-temperature eggs for a better rise: Cold eggs seize the butter or oil in the batter, creating a dense, flat muffin. If you forgot to take them out of the fridge, place the whole eggs in a bowl of warm tap water for 5 minutes — they will feel neutral to the touch, not cold, when ready.
- Do not overmix the batter after adding the flour: Gluten develops the more you stir, and too much gluten makes muffins rubbery rather than tender. Stop mixing as soon as the dry ingredients disappear into the wet ones, even if the batter looks slightly lumpy.
- Chill the streusel butter if your kitchen is warm: Soft butter melts into the flour rather than forming crumbly clumps, which means your topping will bake into a flat, greasy layer instead of a crunchy lid. If the butter feels soft when you cube it, pop the streusel mixture into the freezer for 5-10 minutes before sprinkling it on the batter.
- Line your muffin tin with paper cases for effortless cleanup: The streusel can drip sticky sugar onto the tin during baking, and scrubbing that off is tedious. Paper cases catch all the mess, so you only have one bowl, one spoon and a spatula to wash afterwards.
- Make the dry mix the night before: Combine the flour, sugar, baking powder, bicarbonate of soda and salt in a sealed container or zip-top bag. In the morning or after dinner, you only need to add the wet ingredients and fruit — the whole process takes less than 10 minutes from start to oven.
- Resist the urge to open the oven door early: Muffins need a consistent blast of heat to dome up properly. If you peek at the 10-minute mark, cold air rushes in and deflates the tops, leaving you with flat, sad muffins. Wait until at least minute 16 before checking.
Delicious Variations to Try
- Spicy Version: Add ½ teaspoon of ground ginger and ¼ teaspoon of white pepper to the flour mixture. The gentle warmth of the ginger complements the lemon beautifully, while the white pepper adds a subtle tingle on the tongue that cuts through the sweetness of the streusel.
- Vegan Option: Replace the eggs with two flax eggs (2 tablespoons ground flaxseed mixed with 5 tablespoons water, left to thicken for 10 minutes until it forms a gel-like consistency). Use a plant-based yoghurt, such as coconut or soya, and swap the butter in the streusel for a solid coconut oil — chill the oil cubes just as you would the butter.
- Different Protein: Swap the blueberries for diced strawberries or raspberries, and add 50g of finely chopped pistachios or almonds to the streusel for extra crunch. The nuts toast during baking and release a warm, nutty aroma that pairs wonderfully with the citrus.
What to Serve With Lemon Blueberry Streusel Muffins
- A tall glass of Sparkling Raspberry Lemonade — the bubbles and tart raspberries echo the lemon notes in the muffins.
- A dollop of clotted cream or thick Greek yoghurt on the side to balance the sweetness.
- For a complete dessert spread, pair these muffins with a scoop of Refreshing Peach Sorbet for a light, fruity finish to the meal.

Frequently Asked Questions
Can I use buttermilk instead of Greek yoghurt?
Yes, you can substitute the Greek yoghurt with an equal amount of buttermilk, though the batter will be slightly thinner. The muffins will still bake up tender and moist, but they may not dome quite as high because buttermilk has less fat than yoghurt. If you do swap, reduce the lemon juice by half a tablespoon to keep the acidity balanced.
How do I stop the streusel from sinking into the batter?
The key is to chill the streusel mixture for 10 minutes before sprinkling it on top, especially if your kitchen is warm. You should also avoid pressing the streusel into the batter too firmly — a light, gentle sprinkle is enough. If the butter in the streusel melts before the muffins set in the oven, the crumbs will sink and disappear.
Can I make these muffins gluten-free?
Absolutely, swap the plain flour for a good-quality gluten-free all-purpose blend that contains xanthan gum, such as those from Doves Farm or Freee. Measure by weight rather than volume because gluten-free flours behave differently. You may need to add an extra tablespoon of yoghurt if the batter feels too dry and crumbly.
Why did my blueberries sink to the bottom of the muffins?
This usually happens when the batter is too thin or the berries are too heavy. Tossing the blueberries in a tablespoon of flour before folding them in creates a light coating that helps suspend them in the batter. Also, make sure your blueberries are not overly juicy — if using frozen, do not thaw them first, as excess liquid makes them sink.
How should I store leftover muffins?
Place completely cooled muffins in an airtight container lined with a sheet of kitchen paper at the bottom. The paper absorbs any excess moisture, keeping the streusel crunchy for up to three days at room temperature. For longer storage, wrap each muffin individually in cling film and freeze in a zip-top bag for up to two months — thaw at room temperature for 30 minutes before serving.

Notes
Do not thaw frozen blueberries before adding. Overmixing batter results in tough muffins. Streusel should clump slightly when squeezed.
