A zesty Lemon Blueberry Cake that brings together tangy citrus and sweet berries in delightful balance. Every bite offers moist vanilla cake dotted with juicy blueberries and infused with fresh lemon zest, all covered in fluffy lemon buttercream.
Whipping up this cake always takes me back to wonderful summer days. When those juicy berries pop while baking, making little pockets of sweet goodness next to the tangy lemon flavor, you can tell you're making something truly amazing.
Key Ingredients
- Fresh Blueberries: Frozen work too, don't thaw
- Fresh Lemons: You'll need both zest and juice
- Unsalted Butter: Make sure it's softened
- Large Eggs: Take them out early to warm up
- Whole Milk: Adds softness
- All-Purpose Flour: Gives the cake body
- Pure Vanilla Extract: Adds richness
- Baking Powder: Check it's not expired
- Kosher Salt: Boosts all tastes
STEP-BY-STEP PREPARATION
- 1. Initial Setup:
- Heat oven to 350°F. Get two 9-inch round pans ready with cooking spray and parchment paper circles. Let all ingredients come to room temp. Mix lemon zest with sugar until it smells amazing.
- 2. Cake Base:
- Mix butter with your lemon sugar until it's fluffy and pale, about 3-4 minutes. Put in eggs one by one, mixing well after each. Switch between adding dry stuff and milk mixture, starting and finishing with flour.
- 3. Smart Layering:
- Put 1½ cups of plain batter in each pan first - this stops berries from dropping to the bottom. Mix 1 cup blueberries into what's left and split between pans. Scatter remaining berries on top.
- 4. Baking Process:
- Bake 35-42 minutes until edges turn golden and a toothpick comes out clean. Let sit in pans for 15 minutes, then move to cooling rack until completely cool.
- 5. Frosting Creation:
- Beat butter until it's super fluffy. Slowly add sifted powdered sugar, then mix in lemon juice and vanilla. Whip for 4-5 minutes until it's really light.

The magic is in getting everything just right. My baking teacher always told me, "You build an amazing cake one careful step at a time, starting from the bottom."

Storing And Planning Ahead
You can make parts a day ahead: wrap plain cakes in plastic wrap and leave at room temp, and keep frosting in the fridge. When you're ready to put it all together, let frosting warm up and beat again if needed. The finished cake stays good in the fridge for up to 5 days, but let it sit out for a bit before eating so the flavor and texture are at their best.
Serving Ideas And Temperature Tips
This cake tastes best at room temperature when the lemon flavor really pops and the cake feels super soft. In summer, add fresh berries and mint on top. For fancy events, try adding edible flowers or candied lemon pieces. It goes great on a dessert table with other fruit treats.

Fun Twists And Changes
Switch things up during berry season by using different fruits - raspberries, blackberries, or a mix work great. Add a hint of almond extract to the cake mix, or try orange or lime zest for a different citrus kick. For special times, put lemon curd or berry jam between the layers. While you can play around with the recipe, nothing really beats the classic combo of lemon and blueberry for capturing that summer feeling.
