Make this bright and flavorful lemon blackberry loaf with fresh lemon, juicy berries, and a simple sweet frosting. It’s a gluten-free treat that’s easy to prepare and ideal for any time of day.
Grease and line loaf pan with parchment paper. Preheat oven to 350° F.
In a bowl, whisk the flour, baking powder, baking soda, and salt.
In mixer, mix the sugar and the eggs for a full 2 mins on medium speed.
Add butter and oils, mix again.
Add the vanilla, lemon extract, lemon zest and lemon juice. Mix on medium speed until combined. Then, mix in sour cream.
Slowly combine dry with wet and mix until just combined. (Do not over-mix).
In a small bowl, mix blackberries and 1 tablespoon of flour until well coated. Once coated, gently stir into the mixture.
Fold into prepared baking pan and bake for 45-50 mins until toothpick comes out clean.
Frosting
In a bowl whisk together the powdered sugar, lemon juice, and heavy cream until combined. Adjust powdered sugar or cream to make frosting your preferred consistency.
Pour over cooled cake.
Notes
Prevent sinking berries by lightly tossing blackberries in a bit of flour before adding them to the batter. This helps them stay evenly distributed as the loaf bakes.
Bringing the eggs, sour cream, and butter to room temperature helps everything mix better and results in a softer texture.
Stir the batter until just combined to keep the loaf tender. Overmixing can lead to a dense or gummy texture.
Fresh lemon juice and zest give the loaf its bright, citrusy flavor. Bottled lemon juice might not deliver the same result.
