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 200°C (180°C fan-forced / 400°F / Gas Mark 6). Line a 12-hole muffin tin with paper cases.
- In a large mixing bowl, combine the melted butter, caster sugar, and the grated zest and juice from the large lemon. Whisk together.
- Add the Greek yoghurt, eggs, and vanilla powder (use half this amount if you prefer less rich vanilla flavor) to the bowl. Whisk until smooth and well combined.
- In a separate bowl, sift together the flour, baking powder, bicarbonate of soda, and salt. Add the poppy seeds and stir.
- Fold the blueberries into the batter, being careful to distribute them evenly without crushing.
- Divide the batter evenly among the 12 muffin cases. Bake for 18-20 minutes, or until the tops are golden and a skewer inserted into the center comes out clean.
- While the muffins cool, make the glaze. In a small bowl, combine the sifted icing sugar with 1 tablespoon of fresh lime juice. Stir to form a smooth glaze. If it’s too thick, add up to another ½ tablespoon of lime juice.
- Once the muffins have cooled slightly, drizzle the lime glaze over the tops. Allow the glaze to set before serving.
Variations
- Make mini muffins for a bite-sized treat by using a mini muffin tin; reduce baking time to 12-15 minutes.
- Create a streusel topping by combining a tablespoon of the muffin batter’s flour and sugar with a pinch of cinnamon and some cold butter, sprinkling it on before baking for a crunchy top.
- Serve them as a dessert by splitting a muffin and topping each half with a dollop of whipped cream or lemon curd.
- For a more intense lemon flavor, brush the warm muffin tops with some of the leftover lemon juice before applying the glaze.
Tips for Success
- Ensure your melted butter is cooled to avoid cooking the eggs when you mix them in.
- For professional-looking muffins, fill any empty spaces in the tin with a little water to ensure even baking.
- If using frozen blueberries, toss them in a tablespoon of the measured flour before adding to the batter to prevent them from bleeding too much.
- Use a light folding motion when combining the dry and wet ingredients and adding blueberries to keep the muffins light and tender.
Storage & Reheating
Store the muffins in an airtight container at room temperature for up to 2 days, or refrigerate for up to 5 days. To reheat, warm them in a microwave for 15-20 seconds or in a preheated oven at 180°C for 5 minutes to refresh the texture.
FAQ
Can I use regular granulated sugar instead of caster sugar?
Yes, you can, but caster sugar dissolves more easily, creating a finer texture. Granulated sugar will work fine.
Why is bicarbonate of soda used with baking powder?
The bicarbonate of soda reacts with the acidity in the lemon juice and yoghurt, providing an extra lift for a lighter muffin alongside the baking powder.
My blueberries sank to the bottom. How can I prevent this?
Ensure your batter is not too thin, and gently fold in the berries at the very end. Using frozen berries (without thawing) can also help them stay suspended.
Can I make the glaze with lemon juice instead of lime?
Absolutely. The lime glaze adds a distinct note, but using the leftover lemon juice is a perfect and delicious alternative.
What’s the difference between using Greek yoghurt and sour cream?
Both work excellently to add moisture and a slight tang. Greek yoghurt makes a slightly denser, protein-rich muffin, while sour cream creates a very tender, rich crumb.
How do I know when the muffins are done baking?
A skewer or toothpick inserted into the center of a muffin should come out clean or with just a few dry crumbs attached. The tops should be springy and golden.
