To create this scrumptious Lemon Blueberry Cake, here’s what you’ll need:
- 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 (fresh recommended)
- 2 teaspoons cake flour (or all-purpose flour)
For the 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 additional 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 your oven to 350°F (180°C). Grease and flour a 9×13 inch cake pan. If you prefer a layered cake, line the bottom with parchment paper and grease the sides.
-
Sift together the cake flour, baking powder, baking soda, and salt in a medium bowl. Set aside.
-
In another bowl, whisk together the buttermilk and lemon juice until well combined.
-
In a large mixing bowl, cream the softened butter, granulated sugar, and lemon zest until light and fluffy, about 2-3 minutes. Beat in the vanilla extract and add eggs, one at a time, scraping the bowl sides as you go.
-
With the mixer set to low, alternate adding the dry flour mixture and the wet buttermilk mixture until just combined. Be careful not to overmix!
-
Toss the blueberries with 2 teaspoons of flour to prevent them from sinking, then gently fold them into the batter.
-
Pour the batter into the prepared pan and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
-
Let the cake cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
-
For the frosting, beat the softened butter with cream cheese until smooth. Gradually incorporate lemon juice and powdered sugar until you reach the desired consistency, adding whipping cream if needed.
-
Serve the cake plain or decorate it with a dusting of powdered sugar, lemon slices, or whipped cream for that extra special touch.
Best Ways to Enjoy It
This Lemon Blueberry Cake is a versatile treat that can be served in several delightful ways. Enjoy it plain for a simple afternoon snack, or go the extra mile by drizzling the top with glaze or a swirl of cream cheese frosting for a more decadent dessert. Pair it with a scoop of vanilla ice cream or a dollop of whipped cream for indulgence, or serve it alongside a cup of tea or coffee—a perfect balance to the cake’s zesty flavors.
Keeping Leftovers Fresh
If you happen to have any leftovers (which is rare!), storing them correctly will ensure they stay fresh. Keep the cake covered at room temperature for a couple of days. Alternatively, you can store it in the refrigerator for up to a week. For long-term storage, consider wrapping individual slices in plastic wrap before placing them in an airtight container or freezer bag to freeze the cake for up to three months. When ready to enjoy, simply thaw in the fridge overnight.
Helpful Cooking Tips
- Room Temperature Ingredients: Make sure your butter, eggs, and buttermilk are at room temperature. This makes mixing easier and helps create a smoother batter.
- Gentle Mixing: When folding in the blueberries, be gentle to avoid breaking them up; you want some whole berries in your cake for that burst of flavor!
- Test for Doneness: Always use a toothpick to test doneness. A few crumbs on the toothpick indicate a perfectly moist cake.
Creative Twists
If you’re feeling adventurous, here are some fun variations to try:
- Berry Mix: Swap blueberries for raspberries or strawberries, or mix all three for a berry medley.
- Zesty Variations: Add more citrus flavor by substituting lime or orange zest in the batter for a unique twist.
- Dietary Adjustments: Make it gluten-free by using a good quality gluten-free cake flour blend.
