- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup unsalted butter (softened)
- 1 cup granulated sugar
- 2 large eggs

- 1 tablespoon lemon zest (from about 1 lemon)
- 1/2 cup buttermilk (or milk with 1/2 tablespoon vinegar)
- 1 cup fresh blueberries (or frozen, if necessary)
For the Crumb Topping:

- 1/3 cup brown sugar (packed)
- 1/4 cup unsalted butter (melted)
- 1/2 teaspoon cinnamon (optional)
- Pinch of salt
Timing
Making Lemon Blueberry Crumb Loaf takes about 15 minutes for preparation and 50-60 minutes for baking.
Instructions
Step 1: Preheat Oven
- Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×5-inch loaf pan or line it with parchment paper.
Step 2: Prepare the Crumb Topping
- Mix Topping Ingredients: In a small bowl, combine the flour, brown sugar, melted butter, cinnamon (if using), and a pinch of salt. Mix until crumbly and set aside.
Step 3: Prepare the Loaf Batter
- Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
- Cream Butter and Sugar: In a large bowl, beat the softened butter and granulated sugar together until light and fluffy, about 2-3 minutes.
- Add Eggs and Flavorings: Add the eggs, vanilla extract, and lemon zest to the butter mixture, beating well to combine.
- Combine with Dry Ingredients: Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk. Mix until just combined. Gently fold in the blueberries.
Step 4: Assemble the Loaf
- Pour Batter into Pan: Pour the batter into the prepared loaf pan, smoothing the top with a spatula.
- Add Crumb Topping: Sprinkle the crumb topping evenly over the batter.
Step 5: Bake
- Bake: Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted into the center comes out clean. If the top is browning too quickly, cover it loosely with aluminum foil.
Step 6: Cool and Serve
- Cool: Allow the loaf to cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely.
- Slice and Enjoy: Once cooled, slice the loaf and serve. It’s delicious on its own or with a spread of butter.
