Blueberries and lemons are a classic flavor pairing for spring desserts, and this light, moist cake is a great example of how well those two ingredients go together.

Loaded with fresh lemon flavor and juicy blueberries, our lemon blueberry loaf cake uses a special ingredient you don’t usually find in baked goods – frozen lemonade concentrate.

The lemonade adds both sweetness and a bright, lemony flavor that’s accentuated with the addition of fresh lemon zest. In the interest of conserving calories, we’ve kept additional sugar to a minimum too, something we try to do in all of our dessert recipes.

What’s the difference between loaf cake, pound cake, and quick bread?

There’s a variety of non-yeasted baked goods you can make in a loaf pan. You’ll find recipes labeled as quick breads, pound cakes or, as in this case, a loaf cake. So what’s the difference between them?

True to their name, quick breads are breads that are quick to make because they don’t include yeast and therefore require no rising time. These breads are leavened with baking powder and/or eggs and if you want to get technical, this category also includes muffins, biscuits and scones.

A classic recipe for pound cake is made with a pound each of flour, sugar, butter, and eggs, and flavored with vanilla. Most modern recipes aren’t quite that rich, but the dense texture and buttery flavor that formula produced is still the goal when making a pound cake.

A loaf cake is a much more forgiving term, essentially being any cake baked in a loaf pan. For our purposes, we’re giving this recipe that label because it has a finer texture than most quick breads and is far less rich and dense than a pound cake.

More easy cake recipes:

To us, an easy cake recipe is one that requires no frosting and we have a few more that fit that bill. Our Golden Delicious Coffee Cake is topped with thin slices of apple instead of streusel or frosting.

Upside down cakes fall into the frosting-free category too. Both our Apple Gingerbread Upside Down Cake and Cranberry Upside Down Cake are fall-inspired twists on the traditional pineapple version.

Chock full of juicy blueberries, this easy-to-make, lemony loaf cake is light, moist, and as desserts go, relatively low in calories and fat.


  • 1 cup blueberries, washed, drained and patted dry
  • 2 cups all-purpose flour
  • 1/2 cup granulated sugar
  • 2 teaspoons baking powder
  • 1/4 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 large egg
  • 1/3 cup canola oil
  • 3/4 cup whole milk
  • 1/4 cup frozen lemonade concentrate, thawed
  • Zest of 1 lemon
  • 1 tablespoon coarse sugar for decorating, optional

For the glaze:

  • 2 tablespoons confectioners’ sugar
  • 1 teaspoon freshly squeezed lemon juice


  • Preheat the oven to 350°F and lightly grease a standard (8-1/2″ x  4-1/2″) loaf pan with butter (see notes).
  • Place the blueberries in a small bowl, add 1 tablespoon of the measured flour and stir until thoroughly coated. Set aside.
  • Whisk the flour, sugar, baking powder, baking soda and salt together in a large mixing bowl.
  • In a separate bowl, whisk the egg, oil, milk, lemonade concentrate and lemon zest together until frothy.
  • Pour the wet ingredients into the dry and combine with a spatula until all the dry ingredients have been incorporated. Do not over mix.
  • Gently fold the blueberries into the batter, mix well and transfer to the prepared loaf pan. Sprinkle the top with coarse sugar if desired.
  • Bake for 50 to 60 minutes or until the top of the cake is golden brown and a toothpick inserted in the center comes out clean.
  • Cool in the pan for 10 minutes, then turn out onto a cooling rack.
  • Once the cake has cooled completely, combine the confectioners’ sugar and lemon juice, stirring until smooth.
  • Brush the glaze onto the cake, let sit for a few minutes, then slice and serve.

Tips for Making This Recipe

Loaf pan size: It’s okay to use a 9" x 5" loaf pan if you don’t have the 8-1/2" x 4-1/2" size – it just won’t be quite as tall. Just remember to check your bread for doneness after about 45 minutes instead of 50 minutes as stated in the recipe.
