This lemon blackberry loaf is soft, moist, and bursting with fresh lemon flavor and juicy blackberries. An easy bakery-style loaf cake perfect for brunch, dessert, or summer baking.
Preheat your oven to 350 F /180 C. Butter and flour a 9 x 5 inch loaf pan or or line it with parchment paper.
In a bowl, stir the flour with the baking powder and salt.
In a small bowl using your fingers, rub the fresh lemon zest into the granulated sugar to make lemon sugar.
In the bowl of your electric mixer (fitted with the paddle attachment), or with a hand mixer, beat the softened butter and lemon sugar on medium-high speed until the mixture is light and fluffy (about 5 minutes).
Add the eggs, one at a time, beating well after each addition. Beat in the vanilla and lemon extract.
Add the flour mixture, in two additions alternating with the yogurt and lemon juice, and mix just until incorporated.
In a separate small bowl, toss the blackberries with the remaining 1 tablespoon of flour (to prevent sinking), leaving any excess flour in the small bowl.
Gently fold in the blackberries. Pour the batter into the prepared loaf pan and smooth the top.
Bake for about 55-60 minutes or until the cake is golden brown and a toothpick inserted in the center comes out clean.
Remove the cake from the oven and place on a wire rack to cool for about 20 - 30 minutes. Then remove the cake from the pan to finish cooling.
While the loaf cools, in a small bowl, make the lemon glaze by whisking together the powdered sugar and lemon juice until it’s completely smooth.
Drizzle the glaze over the top of the loaf, allowing some to drip down the sides. Allow to cool completely before slicing.
Notes
Tent with foil if needed: If the top of the loaf begins browning too quickly, loosely cover it with aluminum foil during the last 10–15 minutes of baking.
Cool before slicing: Allow the loaf to cool completely before slicing so the crumb sets properly and the slices stay neat.
Pan size adjustment: If using an 8×4-inch loaf pan, reduce the ingredients to about 75% of the original recipe to prevent the pan from overflowing.
