Lemon Blueberry Loaf Cake

My mom dropped by yesterday, and since she’s always open to trying experiments, I made her this lemon blueberry loaf cake. Keeping with this week’s theme of baking accidents, I forgot to add the baking soda and had to pull the cake out of the oven and stir it into the hot batter. Despite that, the cake still rose okay and tasted great. It was really tight crumbed, moist, and not too sweet.

My loaf pan is a little larger than most so the cake is kind of wide and I ended up cutting it into squares instead of slices. They looked okay , but I think it might rise higher and look better in an 8 ½ x 5 (ish) pan. That aside, the cake was really good. It was so good that I wish I’d kept it, but I gave it away and have to make another one.

Update: Since posting this recipe I’ve made it many times — without forgetting the baking soda! Here are some more recent photos. These versions do not include the icing and the cake is just fine without it. For the lemon, I like to add juice, zest and lemon oil (Boyjian). And I really pack the bread with blueberries.

Lemon Blueberry Loaf Cake made with sour cream, fresh blueberries and lots of lemon.
Recipe type: Dessert
Cuisine: American
Serves: 12
  • 3/4 cup to 1 cup fresh blueberries
  • 1 stick (4 oz) unsalted butter, cool room temperature (or 4 T. butter and 4 T. shortening)
  • 1/2 scant teaspoon salt
  • 1 cup granulated sugar (196 grams)
  • 3 large eggs, room temperature (150 grams)
  • 1 1/2 cups all purpose flour (6.8 oz)
  • 1/4 teaspoon baking soda
  • 3/4 teaspoon lemon extract or 1/2 teaspoon good Boyjian lemon oil
  • 2 1/2 teaspoons lemon zest**
  • 1 tablespoon fresh lemon juice
  • 1/2 cup sour cream, room temperature
  • 2 teaspoons butter
  • 1/2 cup sifted powdered sugar
  • 1-2 tablespoons lemon juice
  1. Put the berries in the freezer for about 30 minutes to freeze – this will help keep them from staining the batter.
  2. Preheat oven at 350 degrees F. Grease an 8 1/2 by 4 1/2 inch loaf pan (9x5 is okay too) and line with a strip of parchment. Dust with flour.
  3. In a stand mixer with the paddle attached, cream the butter, salt and sugar until light and fluffy. On low speed, add the eggs one at a time letting the mixer go for 30 seconds (increasing speed slightly) after each egg. Scrape sides of bowl often.
  4. By hand or with lowest speed of mixer, add all but two teaspoons of the flour (leave the 2 teaspoons behind to dust the blueberries). Stir in baking soda, making sure it doesn't clump, then stir in lemon juice, lemon zest and lemon flavoring. Stir in the sour cream. Remove bowl from the stand, toss the frozen blueberries in the remaining two teaspoons of flour, then stir into the batter.
  5. Spoon the batter into the prepared loaf pan, smoothing edges. Bake the cake for 60-75 minutes or until a toothpick inserted into the center of the cake is clean or a meat thermometer inserted in the center registers 205 degrees F. Make sure to check the cake at about 50 minutes, and if the top is brown, go ahead and cover loosely with foil.
  6. Set the cake on a rack to cool for about 10 minutes. Loosen sides and let cool for another 20 minutes in the pan. Turn the cake from the pan and let cool completely. Make the glaze. Melt the butter in a bowl, add the sugar and stir until it looks pasty and moist. Add one tablespoon of the lemon juice and stir until smooth. If you need more lemon juice then add the rest. Drizzle over the cake
  7. **For more lemon flavor, add up to 4 teaspoons lemon zest

    This looks great! I have a bunch of blueberries I picked over the weekend. I don’t have lemon extract thought- do you think the zest and juice is enough?

    That looks great, but it also looks like more than 3/4 cup fresh blueberries. Just right.

    I love that–“in keeping with this week’s theme of baking accidents.” Isn’t that fun with things happen in sometimes large cycles. 😉

    Katherine, they’d be great! But I think they’d be like mini pound cakes rather than actual cupcakes. Still, you could definitely get away with baking them as miniatures.

    Sheena, I’m positive frozen blueberries would be fine :).

    You have no idea how excited I was when I saw this post yesterday! I had just picked a gallon of blueberries and I was looking for things to bake with them!

    I made this cake over the weekend, and it turned out really well! I used an 8×4 loaf pan and frozen berries. Both worked fine. However, next time I will toss my blueberries with a little flour to keep them from sinking to the bottom of the batter.

    You definitely need the glaze for this cake to bump up the lemon flavor. I may add more lemon extract or more zest to the cake next time to increase the lemon flavor. Definitely a keeper recipe.

    Lin, thanks for the feedback! I’m going to incorporate your notes into the original recipe. Thanks again!!!
