Ingredients You’ll Need for Lemon Blueberry Cake

3 cups cake flour (360 grams)
2 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
3/4 cup buttermilk (180 ml) (room temperature)
1/3 cup lemon juice (80 ml) (freshly squeezed)
1 cup unsalted butter (226 grams) (softened to room temperature)
1 3/4 cups granulated sugar (350 grams)
2 tablespoons lemon zest
2 teaspoons vanilla extract
4 large eggs (room temperature)
2 cups blueberries (I recommend using fresh)
2 teaspoons cake flour (or all-purpose flour)

For Cream Cheese Frosting:

1/2 cup unsalted butter (112 grams) (softened)
8 oz brick-style cream cheese (226 grams)
1 teaspoon lemon juice (freshly squeezed)
3 – 4 cups powdered sugar (330-440 grams) (sifted)
1 tablespoon whipping cream (as needed)

For Layer Cake Frosting:

3/4 cup unsalted butter (168 grams) (softened)
12 ounces brick-style cream cheese (340 grams) (full fat)
1 1/2 teaspoons lemon juice (freshly squeezed)
4 1/2 – 5 1/2 cups powdered sugar (495 – 605 grams) (sifted)
1-2 tablespoons whipping cream (as needed)

Step-by-Step Instructions

Preheat the oven to 350F (180C) degrees. Grease and flour a 9×13 inch cake pan. For a layer cake, line the bottom of the cake tins with rounds of parchment paper and grease and flour the sides.
In a medium bowl, sift together the flour, baking powder, baking soda, and salt. Whisk together and set aside.
Combine the buttermilk and freshly squeezed lemon juice in a small bowl. Whisk with a fork and set aside for a moment.
In a large bowl, beat together the softened butter, granulated sugar, and lemon zest until fluffy—about 2-3 minutes.
Add in the vanilla extract and then beat in the eggs one at a time, ensuring to scrape down the sides of the bowl after each addition.
With the mixer on low speed, add about a third of the flour mixture into the butter mixture. Then mix in half of the milk and lemon juice mixture. Turn off the mixer and scrape down the sides and bottom of the bowl. Repeat this process—mixing in another third of the flour, followed by the remaining milk mixture, and finally the last third of the flour. Be cautious not to overmix.
Toss the blueberries with the 2 teaspoons of flour, then gently fold them into the batter using a spatula or rubber spoon.
Pour the batter into the prepared pan or pans. Bake for 30-35 minutes for a 9×13 inch pan or 25-30 minutes for layer cakes. The tops should look set, and a toothpick inserted in the center should come out clean. The top of the cake should feel firm and slightly springy, not gooey.
Allow the cakes to cool in the pan. If you’re making a layer cake, be very gentle when removing the pans; don’t invert them while still hot.
For the cream cheese frosting, use the same process for both the 9×13 inch cake and the layer cake.

Delicious Variations to Try

Lemon Poppy Seed: Add a tablespoon of poppy seeds to the batter for an additional pop of flavor and a delightful crunch.
Mixed Berry Bliss: Swap out some of the blueberries for other berries like raspberries or chopped strawberries for a berry medley.
Lemon Glaze: Instead of frosting, drizzle a simple lemon glaze made with powdered sugar and lemon juice to keep it lighter and zesty!
Zesty Almond: Add a splash of almond extract for a nutty depth that pairs beautifully with the citrus.

Chef Emma’s Helpful Tips

Make-Ahead Option: You can bake this cake a day in advance. Just wrap it tightly in plastic wrap and store it at room temperature until you’re ready to frost it.
Ingredient Swaps: If you’re out of buttermilk, you can substitute it with regular milk plus a teaspoon of vinegar or lemon juice for a similar tangy flavor.
Storage: Keep any leftovers in an airtight container in the fridge for up to five days. It’s perfect for late-night cravings!
Slicing Tips: For clean slices, use a sharp serrated knife and wipe the blade with a damp cloth between cuts.
