I started making these on a Sunday night because I had half a punnet of blueberries going soft in the fridge and one lemon's worth of extract left in the bottle. Six jumbo muffins came out of it, which sounds like a small batch until you see the size of them. One is breakfast. Two is a decision.
The thing that makes these work is the buttermilk and the long creaming. You beat room-temperature butter with sugar for about 4 minutes until it goes pale and fluffy, and that air is what lifts a batter this heavy. Skip it and you get dense muffins that taste fine but feel like work.
One warning before you start: the batter will look slightly grainy after the buttermilk goes in. That's normal. It smooths out the moment the dry ingredients join, so don't panic and don't keep beating to fix it.
Step-by-Step Instructions
1. Heat the oven and line the tin
Set the oven to 350°F (180°C). Put paper liners in all six cups of your jumbo muffin tin. If you don't have liners, grease the cups well with butter or a neutral oil.
2. Cream butter and sugar
Beat the soft butter with the granulated sugar on medium speed for about 4 minutes, until the mixture is pale and visibly fluffy. Scrape down the bowl once halfway.
3. Beat in extract and eggs
Add the lemon extract and beat for another minute. Then add the eggs one at a time, beating 30 seconds after each. The mixture should look smooth and glossy at this point.
4. Add the buttermilk
Pour in the buttermilk and beat just until it's combined. It will look a little grainy or separated. That's expected, so leave it alone and move on.
5. Whisk the dry ingredients
In a separate medium bowl, whisk together the flour, baking powder, baking soda and salt until evenly mixed. A whisk does this faster than a spoon.
6. Combine wet and dry
Sift the dry mixture into the butter mixture. Beat on medium-low just until no dry streaks remain. Stop there, even if the batter looks slightly lumpy.
7. Fold in the blueberries
Scrape down the bowl with a rubber spatula, then gently fold in the blueberries. Use a light hand so the berries stay whole and the batter doesn't turn purple.
8. Fill the cups and sugar the tops
Divide the batter evenly between the six cups, filling each about halfway. Sprinkle a pinch of granulated sugar over the top of each one.
9. Bake and cool
Bake for 25 to 30 minutes, turning the tin halfway through, until the tops are light golden brown and a skewer comes out with moist crumbs. Let them cool 5 minutes in the tin, then lift them onto a wire rack to cool completely.
Pro Tips
How to Store Lemon-Berry Muffins
Refrigerator
Keep cooled muffins in a sealed container at room temperature for up to 2 days, or in the fridge for up to 5. Fridge muffins firm up, so warm them briefly before eating.
Freezer
Wrap each muffin tightly in plastic wrap, then bag them. They keep for up to 3 months. Freeze them fully cooled, never warm.
Reheating
Microwave a single muffin for 20 to 30 seconds, or warm wrapped in foil at 300°F for about 8 minutes. A split muffin toasted cut-side down in a pan is even better.
Frequently Asked Questions
Q: Can I use frozen blueberries instead of fresh?
You can, but don't thaw them first. Toss the frozen berries in a spoonful of flour and fold them in at the last second. The batter will chill and may need 2 to 3 extra minutes in the oven.
Q: Why did my muffins come out dense?
Usually it's under-creamed butter or overmixed batter. Beat the butter and sugar the full 4 minutes, and stop mixing the moment the flour disappears. Old baking powder is the other common culprit.
Q: Can I make these in a regular muffin tin?
Yes, but the yield and timing change. A standard tin holds the same batter across 12 smaller cups, and they'll bake in roughly 18 to 22 minutes. Start checking early.
Q: Do I have to use lemon extract?
It's the main lemon flavor here, so leaving it out gives you plain blueberry muffins. Lemon zest works as a partial stand-in, but you'll need zest from a whole lemon for a similar punch.
Q: How do I know when they're done?
Look for light golden tops and a skewer that comes out with a few moist crumbs. Wet batter means more time. Check at 25 minutes, since ovens vary.
