This lemon blueberry pound cake has a rich, buttery crumb filled with juicy blueberries and fresh citrus flavour. Sour cream keeps the cake moist, while a simple lemon glaze adds sweetness and a bright finish.
The cake is baked in a standard loaf tin, making it easy to slice and serve for brunch, afternoon tea or dessert. It also travels well for picnics, parties and family gatherings.
Fresh blueberries give the neatest appearance, but frozen berries can be used without thawing.

Ingredients You’ll Need

- ½ teaspoon salt.
- ½ cup unsalted butter, softened.

- 3 large eggs, at room temperature.

- ½ cup full-fat sour cream, at room temperature.

Ingredient Notes
Butter: Softened butter should feel pliable but remain cool. Melted or greasy butter will not trap air effectively.
Blueberries: Fresh blueberries remain more evenly distributed. Frozen berries may colour the batter but do not need to be thawed.
Sour cream: Full-fat sour cream adds moisture, richness and a tender crumb.
Lemon: Use fresh lemon juice and finely grated zest. Avoid grating the bitter white pith.
Eggs: Room-temperature eggs combine more smoothly with creamed butter.
Flour: Measure accurately to prevent the cake from becoming dry or heavy.
Can You Use Frozen Blueberries?
Yes. Keep the berries frozen until the batter is ready.
Toss the frozen blueberries with one tablespoon of flour and fold them into the batter gently. Bake the cake immediately after adding them.
Frozen berries can increase the baking time by several minutes and may create purple streaks in the crumb.
How to Make Lemon Blueberry Pound Cake
Step 1: Prepare the Oven and Tin
Preheat the oven to 350°F.
Grease a 9 × 5-inch metal loaf tin.
Line it with parchment paper, leaving an overhang on the long sides.
Step 2: Combine the Dry Ingredients
Whisk the flour, baking powder and salt in a medium bowl.
Set the mixture aside.
Step 3: Cream the Butter and Sugar
Place the softened butter and granulated sugar in a large mixing bowl.
Beat at medium speed for approximately 3–4 minutes, until pale and fluffy.
Scrape the bowl several times so the mixture creams evenly.
Step 4: Add the Eggs
Add the eggs one at a time.
Beat thoroughly after each egg and scrape the bowl before adding the next one.
Step 5: Add the Lemon and Vanilla
Mix in the lemon zest, lemon juice and vanilla.
The mixture may appear slightly curdled after the lemon juice is added. It should become smooth when the flour is incorporated.
Step 6: Add the Flour and Sour Cream
Add one-third of the dry ingredients and mix on low speed.
Add half the sour cream, followed by another third of the flour.
Repeat with the remaining sour cream and finish with the remaining flour.
Mix only until combined.
Step 7: Prepare the Blueberries
Toss the blueberries gently with one tablespoon of flour.
Reserve approximately ¼ cup for decorating the surface.
Step 8: Fold in the Blueberries
Fold the remaining blueberries into the batter using a flexible spatula.
Avoid crushing the fruit or overmixing the batter.
Step 9: Fill the Loaf Tin
Transfer the batter to the prepared tin.
Smooth the top and scatter the reserved blueberries over the surface.
Step 10: Bake the Cake
Bake at 350°F for approximately 55–70 minutes.
The cake is ready when:
- The top is golden.
- The centre springs back gently.
- A skewer inserted away from a blueberry emerges clean or with several moist crumbs.
- The internal temperature near the centre is approximately 200–205°F.
Cover the top loosely with aluminium foil if it browns before the centre has finished baking.
Step 11: Cool Completely
Cool the cake in the tin for approximately 20 minutes.
Lift it out using the parchment and place it on a wire rack.
Allow it to cool completely before glazing.
Step 12: Make the Lemon Glaze
Whisk the icing sugar with 1½ tablespoons of lemon juice.
Add additional juice a small amount at a time until the glaze can be drizzled but remains thick.
Step 13: Glaze and Serve
Drizzle the glaze over the cooled cake.
Allow it to set for approximately 20 minutes before slicing.
Tips for the Best Pound Cake
Use Room-Temperature Ingredients
Butter, eggs and sour cream blend more evenly when they are at a similar temperature.
Cream the Butter Thoroughly
Proper creaming incorporates small air pockets and prevents the loaf from becoming excessively dense.
Measure the Flour Carefully
Spoon flour into the measuring cup and level it with a straight edge.
Alternate the Flour and Sour Cream
Adding them gradually helps maintain a stable batter.
Avoid Overmixing
Stop mixing as soon as the final flour streaks disappear.
Coat the Blueberries
A small amount of flour helps prevent the berries from sinking.
Bake in a Metal Tin
A light-coloured metal tin creates more predictable browning than glass or dark metal.
Cool Before Glazing
A warm cake melts the glaze and causes it to run off.
Common Problems and Solutions
Why Did My Blueberries Sink?
The batter may have been too warm or thin, the berries may have been wet or they may not have been coated with flour.
Why Is My Pound Cake Dense?
Common causes include insufficient creaming, excessive flour, cold ingredients or overmixing.
Why Did the Centre Sink?
The cake may have been underbaked, the oven door may have opened early or too much raising agent may have been used.
Why Is the Outside Dark but the Centre Raw?
The loaf may have been baked in a dark tin or positioned too close to the oven’s heating element. Cover it loosely with foil and continue baking.

Make-Ahead Instructions

How to Store Lemon Blueberry Pound Cake
Store the cake in an airtight container at room temperature for up to three days.
For longer storage, refrigerate it for up to five days. Bring refrigerated slices to room temperature before serving.
Place parchment paper between slices to protect the glaze.

Frequently Asked Questions
Can I replace sour cream with Greek yoghurt?
Yes. Use plain full-fat Greek yoghurt for a similar texture.
Can I use frozen blueberries?
Yes. Fold them into the batter while they are still frozen.
Can I make the cake without lemon?
Yes. Omit the lemon zest and replace the lemon juice with milk.
Why did my cake crack on top?
A central crack is normal for a thick loaf cake because the outside sets before the centre finishes rising.
Can I bake the batter as muffins?
Yes, but the yield and cooking time will need to be tested separately.
How many servings does the loaf provide?
The cake produces approximately 10–12 slices.
