This Lemon Blackberry Loaf is soft, moist, and bursting with bright lemon flavor and juicy blackberries in every bite. Made in one bowl with fresh lemon zest and lemon juice and topped with a tangy lemon glaze, it's simple enough for everyday baking yet elegant enough for brunch, spring gatherings, or an afternoon treat with coffee.
I love making simple loaf cakes, and this Lemon Blackberry Loaf is perfect for spring. With a tender crumb, pops of tart berries, and a fresh citrus finish, this loaf cake strikes the perfect balance of sweet and tangy.
Made with simple pantry ingredients this one bowl lemon blackberry loaf comes together easily and bakes up beautifully every time.

Why You'll Love This Recipe
- Bright lemon flavor: We use both fresh lemon juice and zest to ensure the citrus flavor really shines through.
- Juicy blackberries: Bursting with fruity blackberry flavor in every bite.
- Soft & moist texture: Tender crumb thanks to the yogurt that stays fresh for days!
- Perfect for spring & summer: Ideal for brunch or dessert
Ingredient Notes
- All-purpose flour: Spoon and level for accurate measuring.
- Granulated white sugar: Sweetens the loaf without overpowering the lemon.
- Unsalted Butter: Make sure to use softened room temperature butter.
- Eggs: Use room temperature eggs for even mixing.
- Fresh lemon zest & juice: Adds bright, natural lemon flavor.
- Fresh Blackberries: Look for plump, firm berries. If they are massive, feel free to slice them in half so they distribute more evenly.Fresh or frozen both work. If using frozen, do not thaw.
- Plain yogurt: This is non-negotiable for a moist loaf. It adds fat and acidity, which breaks down gluten for a more tender crumb. Adds moisture and tenderness. You can use full fat sour cream as well.
- Pure Vanilla extract: Enhances the overall flavor of the cake.
- Pure Lemon Extract: Optional here but it adds a nice extra zesty kick to this loaf.
- Baking powder: Provides lift for a soft loaf.
- Salt: Balances sweetness and enhances flavor.
- Confectioner’s sugar: Used for the glaze. Make sure its sifted to prevent any lumps in the frosting.
Substitutions & Variations
- Frozen blackberries: But do not thaw them. Use them straight from the freezer and toss them in flour. Note that your batter may turn a bit more purple/blue as they bake.
- The Berry Swap: Not a fan of blackberries? This recipe works perfectly with blueberries or raspberries.
- Dairy-Free: Substitute the butter with melted coconut oil and use a dairy-free plain Greek yogurt in place of yogurt/sour cream.
- Add Poppyseeds: Add 1 tablespoon of black poppyseeds for a classic “Lemon Poppyseed” crunch.
Step-by-Step Instructions
Here is how to make this lemon blackberry loaf. You can use a stand mixer or a large mixing bowl with an electric mixer. Preheat oven to 350°F (175°C). Butter and line a 9×5-inch loaf pan with parchment paper.
Make lemon sugar: In a large bowl rub white sugar with fresh lemon zest
Mix wet ingredients: In a large bowl, whisk lemon sugar and softened butter until light and fluffy.
Add the eggs and lemon extract to the butter/sugar mixture and mix on high speed for 3-4 minutes.
Combine: Add dry ingredients to wet ingredients along with the yogurt and lemon juice and mix just until combined.
Fold in the blackberries gently.
Pour batter to the prepared pan and spread evenly.Bake for 50-60 minutes, until a toothpick inserted into the center comes out clean (or with just a few moist crumbs).
In a small Whisk powdered sugar with lemon juice until thick and pourable.
Let the bread cool in the prepared loaf pan for 10 minutes, then transfer to a wire rack to cool completely. Drizzle the glaze over the cooled loaf.
Tips & Tricks for the Best Lemon Blackberry Loaf
- Line the pan: Make sure to grease and line your loaf pan with parchment for easy removal.
- The Flour Toss: Toss your blackberries in 1 tablespoon of flour before folding them into the batter. This creates a “grip” that prevents the berries from sinking to the bottom of the pan.
- Don’t Over-Mix: Once the flour goes in, fold gently until no streaks of flour remain. Over-mixing leads to a tough, bready texture rather than a soft cake.
- The Glaze Timing: Wait until the loaf is completely cool before glazing. If the cake is even slightly warm, the glaze will melt and soak into the cake rather than sitting perfectly on top.
- The “Cracked” Top: For that perfect bakery-style crack down the middle, take a knife dipped in melted butter and draw a line down the center of the batter right before putting it in the oven.
- Tent with foil: If the top of the loaf is browning too quickly, loosely cover it with aluminum foil.
FAQ's
Overmixing or underbaking can cause sinking. Bake until fully set.
This usually happens if the berries were too wet or if you used too much lemon juice in the batter. Make sure to measure your juice accurately!
Tent the loaf loosely with aluminum foil for the last 15 minutes of baking. This allows the center to finish cooking without burning the top.
Storage & Freezing
Storage: Because of the fresh berries I recommend storing this lemon blackberry loaf in the refrigerator for up to 5 days. Bring to room temperature before serving.
Freezing: Wrap the cooled loaf or individual slices tightly and freeze for up to 2 months. Thaw at room temperature before serving.

- 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.

- 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.
