Ingredients
  

Crumble

  • 2 Tbsp unsalted butter, melted
  • 3 Tbsp white granulated sugar
  • cup (40 g) all-purpose flour
  • Pinch salt

Lemon Blueberry Loaf

  • cups (180 g) all-purpose flour (plus a few Tbsps to flour the blueberries)
  • tsp baking powder
  • ½ tsp salt
  • 1 cup (225 g) white granulated sugar
  • 1 Tbsp fresh lemon zest (from 1 large lemon or 2 medium lemons)
  • ¾ cup (169.5 g) unsalted butter, softened
  • 3 large eggs
  • ¼ cup (59 ml) milk
  • 3 Tbsp lemon juice (from 1 large lemon)
  • 1 tsp vanilla extract
  • cups (150 g) fresh blueberries (divided)

Lemon Icing or Glaze

  • ½ cup (62.5 g) powdered sugar
  • ¾ Tbsp lemon juice (or to taste)
  • ½ Tbsp milk (add more to thin it out)

Instructions
 

To Make the Crumble:

  • Mix all of the ingredients for the crumble in a small bowl, cover, and refrigerate until just before baking.

To Make the Lemon Blueberry Loaf:

  • Preheat the oven to 350°F (180°C) and prepare a 9×5-inch (23×13 cm) loaf pan by greasing and flouring it or by spraying it with cooking spray and covering it with parchment paper.
  • In a large mixing bowl, whisk the all-purpose flour, baking powder, and salt and set aside.
  • In a separate bowl, rub the sugar with the lemon zest using your fingers to release the oil from the lemon zest. This will intensify the lemon flavor in the cake.
  • With the mixer running on medium-low speed, cream the butter. Then add the sugar and lemon zest mixture and mix until well combined.
  • Incorporate the eggs, one at a time, while you continue mixing.
  • Add the milk, lemon juice, and vanilla extract.
  • Add the dry ingredients to the batter and mix to incorporate. Scrape the sides and bottom of the bowl with a spatula to make sure everything is well blended.
  • Toss the blueberries with a few tablespoons of all-purpose flour and then fold in 1 cup (100 g) of the blueberries into the batter.
  • Pour the batter into the prepared loaf pan. Top with the remaining ½ (50 g) cup of blueberries, followed by a layer of the chilled crumble.
  • Bake for 55 minutes to 1 hour or until a toothpick or skewer inserted in the center comes out clean.
  • Let the loaf cool on a wire rack before drizzling it with the lemon icing.

To Make the Lemon Icing:

  • In a small bowl, whisk together all of the ingredients for the icing, then drizzle it over the cooled lemon blueberry loaf before serving.

Notes

  • Swap the blueberries with raspberries or blackberries, or a combination of both, to give this loaf a different flavor.
  • Make sure the ingredients are at room temperature so they incorporate well with the batter.
  • Skip the hand mixer and whisk everything with a whisk or a spatula, if you prefer.
  • Refrigerate any leftover lemon blueberry cake slices in an airtight container for up to 3-5 days.
  • Freeze this lemon blueberry loaf inside a resealable freezer bag or container for up to 3 months. Let it thaw in the refrigerator before serving.
  • To make things easier, you can cut the loaf into slices before freezing it and wrap each slice with plastic wrap. That way, you can thaw and enjoy a single slice without having to defrost the entire loaf! 😉
