How to Make Lemon and Blueberry Muffins
Begin by preheating your oven and greasing a muffin tin with spray or lining with muffin paper liners.
In a medium bowl, add the all-purpose flour, baking powder, baking soda, and salt. Mix to combine.
In a separate larger bowl, mix together the sugar, milk, sour cream, applesauce, butter, eggs, and lemon juice. You want to beat this mixture together either by hand or a mixer on low speed until just blended.
Add the dry ingredients to the wet and stir until just moistened. You want to be careful not to over mix, to avoid dry dense muffins.
Gently fold in the blueberries. Try not to over mix, otherwise, your blueberries may start to bleed into the batter and turn your muffins blue.
Fill each muffin cup about 3/4 of the way up and set it aside while you make the easiest streusel topping.
Combine brown sugar and flour in a small bowl, then cut in the cold butter. Mix until all the flour and sugar is moistened and you have noticeable crumbs.
Take this mixture and sprinkle evenly on top of each individual portion of batter waiting in the tin.
Bake until golden brown and a toothpick comes out clean when tested in the center.
Allow cooling before transferring to a wire rack.
Tips and Variations
- These muffins will turn out just as great if you choose to use Bob’s Red Mill one to one gluten-free all-purpose flour.
- If you choose to go with a different type of flour (almond, buckwheat, coconut, etc), keep in mind the texture won’t be the same, but the flavor will still be great. Albeit different!
- Make sure your baking powder and baking soda are always fresh. This is what will activate the rise and the get you fluffy results.
- Use lemon zest in place of lemon juice if you prefer. Or use both!
- Pick up full-fat sour cream. You can replace it with plain Greek yogurt if that’s what you prefer.
- The batter for these muffins will be thick. That’s ok, so don’t try and thin them out!
- Fresh blueberries are best, especially when in season and you have an abundance you want to use. When in a pinch, or when they’re not in season frozen is totally fine.
- You’ll want your butter at two different temperatures. Make sure the butter you’re using in the batter is at room temperature which makes for easy mixing. The butter you cut in the streusel should be cold, straight out of the fridge.
- Make sure your eggs are at room temperature as well, having your ingredients start at the same temperature makes for even baking.
Can I use this recipe with other fruit?
Absolutely! You can swap out the blueberries in this recipe and instead try raspberries, cherries, strawberries, and although it’s not a fruit, chocolate chips!
