How to use frozen blueberries?

No need to wait for the blueberry season to make a batch of blueberry buttermilk muffins recipes and enjoy. Yes, it is possible to make this recipe with frozen blueberries and even your muffins will be just as good.

How to make them? Just follow this blueberry muffin recipe because I use frozen blueberries for the inside and some fresh ones for the outside.

Like all frozen fruit, blueberries will lose water when thawed, so it's best to let them thaw before using them in your recipes.

Place a colander over a bowl, then put your frozen blueberries in the colander, the juice will drain out and you can use your blueberries in your muffins baked goods.

Ingredients and substitutions

Here are the ingredients needed and possible substitutions to make these blueberry buttermilk muffins at home, scroll down to see the quantities in the recipe card.

Muffins batter

• Flour: Use preferably cake flour or all-purpose flour and measure the quantities with an electronic scale to be precise. For gluten-free muffins, use rice flour.
• Butter and oil: Use a mixture of unsalted butter and vegetable oil like rapeseed oil or grape seed oil.
• Sugar: Use granulated sugar that will dissolve quickly and give a nice smooth texture.
• Eggs: Take your eggs out at least 30 minutes before making this recipe so that they are at room temperature.
• Buttermilk: If you don't have buttermilk, you can substitute it with sour cream, plain yogurt, Greek yogurt, or milk.
• Leavening agents: To make the batter rise and get that nice bump, I use a combination of baking powder and baking soda.
• Lemon juice: To flavor this recipe add fresh lemon juice and lemon zest or a small amount of bottled lemon juice.
• Salt and vanilla: And to bring out all the flavors don't forget the little pinch of salt and pure vanilla extract.

Streusel topping

• Flour: Use only all-purpose flour, which can be replaced by wholemeal flour.
• Brown sugar: preferably flavored sugar such as cane sugar or light brown sugar.
• Butter: Unsalted and cold butter.
• Almond meal: an almond meal that you can also replace with almond flour, oatmeal, or hazelnut meal.
• Cinnamon: Optional add a pinch of cinnamon ground to flavor the crumble topping.

Tips for making fruit muffins

Don't miss these tips to make a success of your fruit muffins and to make sure that the fruit stays in the center of the dough and doesn't fall to the bottom during baking :

1. Place fresh or frozen fruit in a small bowl without waiting for it to thaw.
2. Add a tablespoon of Flour or cornstarch to your fruit and mix so that the flour coats all the fruit

The flour will absorb the humidity of the fruit and in this way the fruit will stick to the muffin batter. Also, the muffin batter must be thick enough to hold them and prevent them from falling to the bottom.

How to make Blueberry buttermilk muffins with crumb topping

1 - Crumble topping (streusel)

1. In a medium bowl combine flour, almond meal, light brown sugar, cold butter, pinch of salt and ground cinnamon.
2. With your hands, mix the ingredients together until you have a compact mixture that you can crumble.
3. Place the streusel in the fridge while preparing the muffins.

Tip: You can add a small handful of oatmeal to your streusel and you have the perfect breakfast muffin.

2 - Muffin batter

1. Mix together the dry ingredients in a separate bowl, flour, baking powder, baking soda, and salt, and set aside.
2. Whisk together the melted butter, vegetable oil, sugar, eggs at room temperature, liquid vanilla extract, and lemon juice in another large bowl. Mix until you have a smooth, homogeneous paste.
3. Then incorporate the flour mixture and buttermilk alternately one after the other in small quantities in the wet ingredients, mixing gently with the whisk or a spatula until you obtain a thick batter with some lumps.
4. Finally, fold in the blueberries and mix gently to incorporate them into the batter.

Tip: You can use a hand mixer or a stand mixer to make the mixtures but to integrate the dry ingredients use only a flexible spatula to avoid over-mixing the muffin batter.

3 - Baking

1. Preheat the oven to 428°F/ 220° and line a muffin tin with baking cups.
2. Fill the muffin cups with the muffin batter using a tablespoon or an ice cream scoop.
3. If desired, place a few fresh blueberries on top, add the crumbled streusel, or simply sprinkle with cane sugar.
4. Bake the muffins for 5 minutes, lower the temperature to 392°F/ 200°C and bake for an additional 20 minutes until the muffins are puffed and golden on top.
5. Let the buttermilk blueberry muffins cool a little before removing them from the muffin pan, then let them cool completely on a wire rack.

Tip: Muffins are done when the toothpick inserted in the center comes out clean or with a few crumbs.

Storage and tips

Room temperature: Store buttermilk blueberry muffins for up to a week at room temperature in an airtight container or in the refrigerator under plastic wrap.

You can reheat them a little in the microwave to make them softer.

How to freeze them?

You can also freeze muffins, when they are completely cooled, by placing them in a box or a bag of conservation and for approximately 3 months. 

To defrost, simply let them come back to room temperature or put them in the microwave for a few moments with the defrost function.

Buttermilk substitute

Since buttermilk is an essential ingredient in this recipe to get that tender muffin texture, I'll give you the tip to replace it and make your own homemade buttermilk if you don't have any:

Simply add a tablespoon of white vinegar or fresh lemon juice to semi-skimmed milk and let it sit for 10 minutes.

You will see its texture thicken and become a bit like curdled milk and you can use this mixture in buttermilk muffin recipes.
