I just made a Lemon Blueberry Pound Cake that’s absurdly moist and dangerously easy to finish off in one sitting, and you need to see why.

Jump to Recipe

I’m obsessed with this Lemon Blueberry Pound Cake because it hits sweet and bright in one dense, sliceable thing. I’ll take it over fancy Bundt hype any day.

Blueberries stud the crumb like tiny fruit bombs and lemon zest sneaks through every bite. It’s the kind of cake that makes mornings better, afternoons, and parties stop.

But it’s not delicate or pretentious, just honest sugar and unsalted butter and fruit doing their job. I love it messy, with crumbs on my shirt.

Classic and shouty and impossible not to eat. Also, I stalk Blueberry Cake Recipes obsessively.

How to Make this

Print Recipe (No Advertisments)

1. Preheat oven to 325°F and grease and flour a 9×5 loaf pan, tapping out excess flour so the cake won’t stick.

2. Whisk together 2 1/2 cups all purpose flour, 1 teaspoon baking powder, 1/2 teaspoon baking soda and 1/2 teaspoon salt in a bowl; set aside.

3. Toss 1 1/2 cups blueberries with the reserved 2 tablespoons flour in a small bowl so they don’t sink to the bottom while baking.

4. In a large bowl beat 1 cup softened unsalted butter and 1 3/4 cups granulated sugar until light and fluffy, about 3 to 4 minutes; you want air in there but don’t overdo it.

5. Add 4 room temperature eggs one at a time, mixing well after each; then stir in 2 teaspoons vanilla extract, 1 tablespoon lemon zest and 1/4 cup fresh lemon juice.

6. Mix together 1/2 cup sour cream and 1/2 cup milk in a measuring cup. Add the dry ingredients to the butter mixture in three additions, alternating with the sour cream mixture and beginning and ending with the dry ingredients. Mix just until combined, do not overmix.

7. Gently fold the floured blueberries into the batter with a spatula so they’re evenly distributed; scrape the batter into the prepared pan and smooth the top.

8. Bake at 325°F for about 60 to 70 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. If the top browns too fast loosely tent with foil.

9. Cool in the pan on a wire rack for 15 minutes, then run a knife around the edges and invert onto the rack to cool completely.

10. Whisk 1 cup powdered sugar with 1 to 2 tablespoons additional lemon juice until you reach a pourable glaze consistency; drizzle over the cooled cake. Slice after the glaze sets and enjoy.

Equipment Needed

5. Whisk (for dry ingredients and glaze)
6. Rubber spatula (for folding blueberries and scraping bowl)
7. Measuring cups and spoons
8. Wire cooling rack and a knife to loosen loaf
9. Toothpick or cake tester (to check doneness)

FAQ

Can I use frozen blueberries?

Yes, you can. Keep them frozen and toss them in the extra 2 tablespoons of flour before folding them in so they dont bleed into the batter. That helps prevent the cake from turning purple and stops the berries from sinking too much.

My blueberries keep sinking to the bottom, what am I doing wrong?

Usually it's because the berries are too heavy for the batter or the batter is too thin. Tossing the berries with a little flour, folding gently, and not overmixing will help. Also spread the batter evenly and tap the pan lightly to remove big air pockets.

Can I swap sour cream or milk if I dont have them?

Sure. Plain yogurt works well in place of sour cream, same amount. For milk you can use buttermilk for extra tang or any dairy or non dairy milk in equal parts, though texture may change slightly.

How do I know when the pound cake is done?

Insert a toothpick in the center, it should come out with a few moist crumbs but not wet batter. The top should be golden and spring back when lightly pressed. Baking time can vary by oven, check around 55 to 70 minutes.

Can I make this ahead or freeze it?

Yes. You can bake, cool completely, then wrap tightly and freeze for up to 2 months. Thaw in the fridge or at room temp. If you plan to freeze, wait to glaze until after thawing so the glaze stays fresh.

How do I get the glaze just right without making it runny?

Start with 1 tablespoon lemon juice added to the powdered sugar and whisk. Add more juice a little at a time until it reaches a thick, pourable consistency. If it gets too thin, add more powdered sugar. Let the cake cool fully so the glaze sets nicely.

Old Fashioned Lemon Blueberry Pound Cake Recipe Substitutions and Variations

All purpose flour (2 1/2 cups): substitute with cake flour for a lighter crumb. Use 2 1/4 cups cake flour plus 2 tablespoons for tossing berries, or make your own by replacing 2 tablespoons of each cup of AP flour with cornstarch. It’ll be a bit more tender but still holds up.
Unsalted butter (1 cup): you can swap with equal parts salted butter if you like a touch more seasoning, just cut the added table salt by 1/4 teaspoon. For a dairy free option use vegan stick margarine 1 to 1, but the texture might be slightly different.
Sour cream (1/2 cup): plain Greek yogurt is the best straight swap, equal amount. It gives the same tang and moisture. If you only have buttermilk, use 1/3 cup buttermilk plus 1/6 cup milk to hit the same volume.
Blueberries (1 1/2 cups): frozen berries work fine, toss them in the extra 2 tablespoons flour and do not thaw. If you prefer a different fruit try raspberries or chopped strawberries, but reduce stirring so they don’t crush and bleed too much into the batter.

Pro Tips

1. Toss the berries in flour like it says, but do it lightly and right before you fold them in. If you overcoat they make big white streaks, if you do it too early the flour soaks up moisture and the berries clump. Work quick so they stay separate.

2. Make sure the eggs and butter are really at room temp. Cold eggs make the batter seize and the texture gets dense. If you forgot to set them out, put eggs in warm (not hot) water for 5–10 minutes and soften the butter on low heat for a few seconds, then chill so it’s not greasy.

3. Don’t overmix once you add the flour. Mix until you can’t see dry streaks and then stop, otherwise the cake will be tough. Fold the berries in gently with a spatula, scrape the bowl sides, but keep your folding calm and slow.

4. Watch the top near the end of baking and tent with foil if it’s getting brown too fast. Also test the center with a toothpick but not right at a berry, they give a false moist crumb. Let the loaf cool almost completely before glazing or the sugar will run off and make a mess.
