Why This Recipe Works

- Buttermilk adds moisture and results in a delicious soft tender muffin without adding extra fat.
- Vanilla extract adds that authentic flavor everyone loves.
Blueberry Buying Guide
When buying fresh blueberries, look for batches with the bloom intact (the faded, waxy looking substance on the outside of the berry. See the photo above). The bloom acts as a barrier from bacteria and seals in moisture. It fades with time so it’s a sure sign of freshness.
Also opt for deep colored blueberries with smooth skin that are plump, dry, and firm. Larger berries tend to be sweeter than smaller blueberries, but are not a sign of maturity.
Ingredients Notes
- Blueberries: I used fresh blueberries for this recipe, however, you can use frozen, To use frozen blueberries in blueberry muffins, just toss them in some flour to coat and help absorb any extra moisture. No need to defrost!
- Buttermilk: If you don’t have buttermilk you can make your own (instructions in the section below) or full fat sour cream, plain or Greek yogurt are all great substitutes.
- Butter: I use salted butter, but unsalted butter is just fine, it’s simply a matter of personal taste. If you have unsalted butter and like to season your muffins simply add a half teaspoon of salt to the mix.
- Vanilla: This recipe calls for vanilla extract, however, vanilla paste is also suitable.
How To Make Your Own Buttermilk
To make your own buttermilk at home, add 1 tablespoon of white vinegar or lemon juice to 1 cup of milk. Full-fat milk is best, low-fat or skimmed milk will still work. Stir and let stand for 5 minutes. The mixture may look a little curdled, but that’s fine.
For this recipe, add 1 tablespoon + ¾ teaspoon of white vinegar or lemon juice to 1¼ cups of milk. Please note that when using homemade buttermilk, your batter will look thinner than as pictured in the step by step instructions below.

Erren’s Top Tips
- To use frozen blueberries in blueberry muffins, just toss them in some flour to coat and help absorb any extra moisture. No need to defrost!
- For mini muffins, bake 9-11 minutes, but keep an eye on them while they bake as mini muffins bake fast.
- This batter should be thick, not fluid. If the batter is too runny, add flour, a tablespoon at a time until it becomes scoopable.
- If the batter looks dry or too thick add extra milk, a tablespoon at a time until the proper consistency is reached.
- Don’t overmix over mixing will result in a dense muffin instead of light and fluffy.
- It’s always best to cream the butter and sugar for at least three minutes, until pale and fluffy for a perfect end result
- For domed tops: Fill the muffin pan papers until they are nearly full. It takes a lot of batter to build a nice dome.

FAQs

What is the secret to making moist muffins?
The secret to moist muffins is not to overmix the batter and to make sure you don’t overcook them. Check the muffins just before the cooking time is up by inserting a toothpick to make sure they are cooked through and remove them from the oven before they begin to burn.
