Lemon Blueberry Cake

Last summer my neighbor brought over a basket of blueberries from her garden and I knew exactly what needed to happen. Something about berries and lemon together just makes sense, like they were always meant to share a plate. This cake became that weekend's project and honestly, it might be the reason she keeps bringing me berries now.

I made this for my sisters birthday and halfway through slicing it she asked if I could bake it for her wedding instead of a traditional cake. The frosting alone had three people asking for the recipe before dessert was even over.

Ingredients

• All-purpose flour: Provides the structure and without it the cake would collapse under its own weight
• Baking powder and soda: These work together to give the cake its rise and tender crumb
• Salt: Enhances all the flavors and balances the sweetness
• Unsalted butter: Adds rich flavor and tenderness to the cake
• Vegetable oil: Keeps the cake incredibly moist for days
• Granulated sugar: Sweetens and helps create that tender texture
• Large eggs: Bind everything together and add structure
• Lemon zest: Where all that bright lemon flavor actually lives
• Fresh lemon juice: Adds tanginess and activates the baking soda
• Whole milk: Adds moisture and richness
• Vanilla extract: Rounds out all the flavors
• Fresh blueberries: Toss them with flour first so they do not sink to the bottom
• Cream cheese: The base for the tangy frosting
• Unsalted butter for frosting: Makes it creamy and spreadable
• Powdered sugar: Sweetens and thickens the frosting

Instructions

Preheat your oven and prepare the pans:

Get your oven to 350°F and grease two 8-inch cake pans with butter and flour or parchment paper so nothing sticks later.

Whisk the dry ingredients together:

In a medium bowl combine the flour baking powder baking soda and salt and set it aside for now.

Cream the butter oil and sugar:

Beat the butter oil and granulated sugar in a large bowl until it looks fluffy and pale about 2 to 3 minutes.

Add the eggs and flavorings:

Beat in the eggs one at a time then mix in the lemon zest lemon juice and vanilla until everything is combined.

Combine wet and dry ingredients:

Add half the flour mixture to the wet ingredients then pour in the milk and finish with the rest of the flour mixing just until incorporated.

Fold in the blueberries:

Gently fold those flour-tossed blueberries into the batter being careful not to crush them.

Bake the cakes:

Divide the batter between your prepared pans smooth the tops and bake for 30 to 35 minutes until a toothpick comes out clean.

Cool completely:

Let the cakes rest in the pans for 10 minutes then turn them onto wire racks to cool all the way before frosting.

Make the frosting:

Beat the cream cheese and butter until creamy then add the powdered sugar lemon juice lemon zest vanilla and salt until smooth and fluffy.

Frost and assemble:

Spread frosting on one layer top with the second cake and frost the top and sides until it looks as good as it tastes.

This cake has become my go-to for potlucks because it travels well and people get genuinely excited when they see it coming out of the box.

Making It Ahead

You can bake the cake layers a day in advance and wrap them tightly in plastic wrap at room temperature. The frosting actually benefits from sitting overnight in the refrigerator since the flavors meld together beautifully.

Serving Suggestions

Slice this cake while it is slightly cool so the frosting holds its shape but the crumb is still tender. A cup of Earl Grey tea or even sparkling wine makes the whole experience feel like a proper celebration.

Storage And Freezing

Keep the cake covered at room temperature for up to three days though honestly it rarely lasts that long in my house. You can freeze unfrosted layers wrapped tightly for up to three months and thaw them overnight before frosting.

• Do not frost frozen cake or the condensation will make the frosting slide right off
• Leftovers can be wrapped individually and frozen for those midnight cake cravings
• The cake actually tastes better on day two when the lemon has had time to permeate every crumb

Berry season always reminds me why I started baking in the first place. This cake captures everything good about summer in a single slice.

Recipe FAQs

→ Can I use frozen blueberries instead of fresh?

Yes, frozen blueberries work perfectly in this cake. Just add them directly from the freezer without thawing to prevent them from bleeding into the batter. Toss them with a tablespoon of flour before folding in to help distribute evenly.

→ How should I store the finished cake?

Keep the cake refrigerated in an airtight container or cake dome. It will stay fresh for up to 5 days. Bring to room temperature for about 30 minutes before serving for the best texture and flavor.

→ Can I make this as a single layer cake?

Absolutely! You can bake the batter in one 9-inch round pan or a 9x13 inch rectangular pan. Adjust the baking time to 40-45 minutes for a single layer, checking for doneness with a toothpick.

→ Why use both butter and oil in the cake?

The combination gives you the best of both worlds—butter provides rich flavor while oil keeps the cake incredibly moist and tender for days. This dual approach ensures a soft texture that doesn't dry out quickly.

→ Can I make the layers ahead of time?

Yes, bake and cool the cake layers completely, then wrap tightly in plastic wrap and freeze for up to 3 months. Thaw overnight in the refrigerator before frosting and serving.

→ What if I want extra lemon flavor?

Brush the cooled cake layers with a simple lemon syrup (equal parts lemon juice and sugar, heated until dissolved) before frosting. You can also add extra lemon zest to the frosting for an intense citrus punch.
