  • Butter: Butter is responsible for the richness and soft texture of this cake. For those adhering to a dairy-free diet, coconut oil is a viable substitute. It’s crucial that the butter used is softened, but not liquefied. To tell if your butter is ready for use, gently press your finger into it. If an indentation is easily formed without the butter losing its form, then it’s at the optimal temperature for use.
  • Sugar: Granulated sugar provides sweetness.
  • Egg: A single large egg contributes to the overall structure and stability of the cake.
  • Lemon juice: Lemon juice brightens the blueberry flavor. Use freshly squeezed lemon juice or bottled.
  • Vanilla extract: This ingredient adds depth and enhances the flavors of the other ingredients. Feel free to use almond extract instead.
  • Flour: All-purpose flour is the base for the cake; for a gluten-free version, use a 1:1 gluten-free flour blend.
  • Baking powder and salt: Baking powder helps the cake to rise and salt is added for flavor.
  • Milk: This ingredient adds moisture to the cake. Use cow’s milk or a dairy-free alternative like soy, almond, or oat milk instead.
  • Blueberries: Blueberries are the star of this cake. You can use frozen and thawed blueberries if fresh are unavailable. If you’ve got extra blueberries, add them to Sheet Pan Pancakes, a Blueberry Dutch Baby, or a refreshing Green Smoothie.
  • Powdered sugar: This ingredient is optional but a dusting adds a sweet finishing touch.

Recipe Variations

This cake is versatile and easy to customize. With simple adjustments, you can tailor the recipe to your personal taste or dietary needs.

  • Gluten-free Blueberry Cake: Substitute all-purpose flour with your favorite 1:1 gluten-free flour.
  • Citrus Zest: Add some lemon, orange, or lime zest into the batter for an additional citrus twist.
  • Nutty Twist: Stir in some chopped almonds or pecans for a crunchy texture.
  • Spiced Blueberry Cake: Infuse your batter with 1/8 teaspoon of ground cardamom, cinnamon, or nutmeg for a warming touch.

Expert Tips

  • Read through the entire recipe and the Ingredient Notes section of the post and gather your ingredients. We provide a lot of information within the body of this recipe post to ensure that your blueberry cake comes out perfectly every time. This cake comes together quickly so it’s a good idea to fully understand the recipe and have everything ready before beginning.
  • Measure Accurately: For best results, measure your ingredients precisely. This is so important. To measure flour correctly, stir the flour in its container with a spoon. Then, use a spoon to scoop flour into a dry measuring cup and slightly overfill. Then, use the back of a knife or other straight-edged utensil to level the flour across the cup. Do not scoop the flour. When you scoop, the flour gets packed too tightly and you will end up with more flour than the recipe calls for.
  • Don’t Overmix: Stir your ingredients until just combined to avoid a dense cake.
  • Check for Doneness: Use a toothpick to check if your cake is done. If it comes out clean or with a few crumbs, it’s ready.

  1. Really tasty and easy to make. For me it’s about 3 good size pieces, or 4 smaller. I used a 6.5 in round cake tin(all i had) and cut the sugar by 1/3 as I don’t like things too sweet and it was spot on. 40 mins to cook.

    However, all my blueberries sunk to the bottom. Didn’t affect the taste, but it would look nicer and maybe ensure blueberry in every mouthfull? Any tips on how to fix that? I tried dusting them with flour before folding them it, but that didnt work.

    1. I’m so glad you enjoyed the cake. I haven’t had the issue of the berries sinking to the bottom but if the batter is more liquidy, then the denser berries will settle to the bottom.

  2. This blueberry cake is delicious! I love the crunchy top. The only problem is that it took almost an hour to bake.

    1. I’m thrilled you enjoyed the blueberry cake, especially the crunchy top – that’s one of my favorite parts too! About the baking time, I totally get where you’re coming from. This cake does indeed take around 40 to 45 minutes in the oven, mostly due to the moisture from the blueberries. Oven temperatures can vary, which can also affect baking time. Just a quick tip: if you used frozen blueberries, they can also extend the baking duration a bit.

  3. This blueberry cake tastes very good and I will make it again; however, I found it a little too sweet for my taste (which is unusual). Next time I will reduce the amount of sugar. Thanks for all the wonderful recipes!

    1. Yes, frozen and thawed blueberries work beautifully. Just pat the thawed blueberries with a paper towel before adding them to the cake.

  4. Made this cake today and it’s absolutely delicious – every bite bursting with blueberries. So yummy! Only thing, it my took 1 hour and 5 minutes to fully bake my cake.

    1. I’m so happy you enjoyed the cake! Oven temperatures vary, for us it takes 40 to 45 minutes to bake.
