Introduction
These muffins perfectly balance bright, tangy lemon with sweet, juicy blueberries and a delightful crunch of poppy seeds. You’ll love how they rise into beautifully domed, bakery-style treats with a tender, moist crumb. A simple lime glaze adds a final, irresistible touch of sweetness and zest.
Prep & Cook Time
- Prep Time: 10 minutes
- Cook Time: 20 minutes
- Total Time: 30 minutes
- Servings: 12 muffins
Ingredients
- 115g unsalted butter, melted and cooled
- 150g caster/super fine sugar
- Grated Zest & Juice of 1 Large Lemon
- 300g Plain (all-purpose) Flour
- 2 teaspoons baking powder
- 1/4 teaspoon bicarbonate of soda (baking soda)
- 1/4 teaspoon salt
- 180ml Greek yoghurt or sour cream
- 2 large eggs
- 1 teaspoon vanilla powder (use half this amount if you prefer less rich vanilla flavor)
- 2 tablespoons poppy seeds
- 225g fresh or frozen (no need to defrost) Blueberries
- 100g icing sugar, sifted
- 1-1 1/2 tablespoons fresh lime juice
Instructions
- Preheat your oven to 220°C (425°F) and line a 12-hole muffin tin with paper cases.
- In a large bowl, whisk together the cooled melted butter, caster sugar, lemon zest, and lemon juice.
- Add the Greek yoghurt (or sour cream), eggs, and vanilla powder (use half this amount if you prefer less rich vanilla flavor) to the butter mixture and whisk until smooth and combined.
- In a separate bowl, sift together the plain flour, baking powder, bicarbonate of soda, and salt. Stir in the poppy seeds.
- Toss the blueberries in a tablespoon of extra flour (from your measured 300g) to coat lightly. This helps prevent sinking. Gently fold the floured blueberries into the batter.
- Divide the batter evenly among the 12 muffin cases, filling them to the very top.
- Bake at 220°C (425°F) for 8 minutes, then reduce the oven temperature to 190°C (375°F) (without opening the door) and bake for another 12-14 minutes, or until a skewer inserted into the center of a muffin comes out clean.
- Let the muffins cool in the tin for 5 minutes before transferring to a wire rack to cool completely.
- To make the glaze, whisk the sifted icing sugar with 1 tablespoon of lime juice until smooth. Add the remaining 1/2 tablespoon if needed for a drizzling consistency. Drizzle over the cooled muffins before serving.
Variations
- Lemon Glaze: Swap the lime juice in the glaze for fresh lemon juice to double down on the citrus theme.
- Crunchy Top: Before baking, sprinkle a teaspoon of coarse sugar or a streusel topping over each filled muffin cup.
- Jumbo Muffins: Use a 6-hole muffin tin, increase the bake time by 8-10 minutes, and adjust the temperature step as directed.
- Mini Muffins: Use a mini muffin tin, reduce the initial high-temperature bake to 5 minutes, and then bake at the lower temperature for 7-9 minutes.
Tips for Success
- For the highest, most beautiful muffin domes, start with a hot oven and fill the muffin cups to the very brim.
- Ensure your melted butter has cooled slightly before adding it to the wet ingredients to avoid cooking the eggs.
- When folding in the dry ingredients and blueberries, mix only until combined. Overmixing leads to dense, tough muffins.
- Coating blueberries in a little flour before folding them in is crucial for preventing them from sinking straight to the bottom.
Storage & Reheating
Store the unglazed or glazed muffins in an airtight container at room temperature for up to 3 days. For longer storage, freeze them in a single layer, then transfer to a freezer bag for up to 3 months. Reheat individual muffins in the microwave for 15-20 seconds to restore a warm, freshly-baked texture.
FAQ
Can I use regular granulated sugar instead of caster sugar?
Yes, though the finer caster sugar dissolves more readily and creates a slightly finer crumb. If using granulated, you may see minimal tiny sugar specks, which is fine.
My blueberries sank. What happened?
The most common reasons are not coating them in flour or overmixing the batter after adding them, which breaks their protective flour coating. Using frozen berries directly from the freezer also helps.
Can I use muffin liners?
Absolutely. Paper liners are recommended for easy removal and cleanup. If not using liners, ensure the muffin tin is very well greased.
Can I make this into a loaf?
Yes, bake it as a quick bread in a greased 9×5-inch loaf pan at 180°C (350°F) for 55-65 minutes. The initial high-temperature step is not used for a loaf.
Why the high initial oven temperature?
The initial burst of high heat helps create a rapid rise, setting the muffin tops into a beautifully domed shape before the inside finishes baking.
What’s the best way to zest a lemon?
Use a fine microplane grater for the most zest with minimal bitter white pith. Zest the lemon before you cut and juice it—it’s much easier.
