How to Make Lemon Blueberry Crumb Loaf
-
Preheat your oven to 350°F (175°C). This ensures your Lemon Blueberry Crumb Loaf will bake evenly, giving you that perfect texture and color. Grease your 9×5-inch loaf pan or line it with parchment paper for easy removal.
-
Combine the crumb topping ingredients in a small bowl. Mix together 1/3 cup all-purpose flour, 1/3 cup brown sugar, melted butter, optional cinnamon, and a pinch of salt until crumbly. Set this delicious mix aside to create that irresistible topping!
-
Whisk together the dry ingredients in a medium bowl. In a separate bowl, mix 1 1/2 cups of flour, baking powder, baking soda, and 1/4 teaspoon salt. This step helps them evenly distribute throughout the batter, ensuring a light, fluffy loaf.
-
Beat the softened butter and granulated sugar in a large bowl until light and fluffy, about 2–3 minutes. This creates the foundation for a tender loaf that melts in your mouth.
-
Add the eggs, vanilla extract, and lemon zest to the butter mixture. Beat well to combine everything into a smooth, luscious batter filled with bright citrus notes.
-
Gradually mix the dry ingredients into the wet ingredients, alternating with 1/2 cup buttermilk. Start and end with the dry mixture, mixing until just combined. Gently fold in 1 cup of fresh blueberries, being careful not to mash them.
-
Pour the batter into the prepared loaf pan, smoothing the top with a spatula. This ensures an even rise and beautiful presentation when it’s finished baking.
-
Sprinkle the crumb topping evenly over the batter. This will create a delightful crunch that contrasts perfectly with the soft interior of the loaf.
-
Bake for 50–60 minutes, or until a toothpick inserted into the center comes out clean. If the top browns too quickly, cover it loosely with aluminum foil to prevent burning.
-
Cool the loaf in the pan for about 10 minutes, then transfer it to a wire rack. Allow it to cool completely, letting those amazing flavors develop even more.
-
Slice and serve this delicious Lemon Blueberry Crumb Loaf. Enjoy it warm or at room temperature, relishing each bite of citrusy berry goodness!

Lemon Blueberry Crumb Loaf Recipe FAQs
How do I choose the right blueberries for my loaf?
Absolutely! Look for fresh blueberries that are plump and firm, with no visible dark spots or shriveling. If frozen blueberries are your go-to, ensure they are unsweetened for the best flavor. Rinse them gently just before adding them to the batter for a burst of juicy goodness!
What’s the best way to store Lemon Blueberry Crumb Loaf?
To keep your Lemon Blueberry Crumb Loaf fresh, store it in an airtight container at room temperature for up to 3 days. If you want to extend its life, refrigerate it in an airtight container for up to 1 week. Just note that refrigeration may slightly alter its lovely texture.
Can I freeze my Lemon Blueberry Crumb Loaf? If so, how?
Definitely! For freezing, wrap the cooled loaf tightly in plastic wrap, then in aluminum foil to prevent freezer burn. This method keeps it fresh for up to 3 months. When you’re ready to enjoy it, simply thaw it overnight in the fridge, and it will be ready to delight your taste buds!
What should I do if my loaf comes out too dry?
Very! If your loaf turns out dry, it may have been overbaked or mixed too much. To avoid this next time, ensure you’re checking it at the lower baking time with a toothpick; it should come out with a few moist crumbs attached. Also, gently handle the batter when folding in ingredients to keep it light and airy.
Is this Lemon Blueberry Crumb Loaf suitable for people with allergies?
Certainly! This recipe contains common allergens like gluten and dairy. If you’re baking for someone with these allergies, consider swapping the all-purpose flour with a gluten-free blend and use a dairy-free butter and buttermilk alternative. The flavor may vary slightly, but it’ll still be delicious!
How long does the crumb topping stay crisp?
For maintaining that delightful crumbly texture, the topping is best enjoyed on the same day of baking. If stored properly, it can stay relatively crisp for up to 3 days at room temperature, but may soften over time. If necessary, you can crisp it up in the oven at 350°F (175°C) for 5-10 minutes before serving!
