A tangy Lemon Blueberry Cake that blends zesty citrus with sweet berries in perfect balance. Every bite offers moist vanilla cake packed with juicy blueberries and flecked with fresh lemon zest, all covered in fluffy lemon buttercream frosting.
Baking this cake always brings back memories of summer's best days. When those juicy berries pop during cooking, leaving pockets of sweet jamminess against the tangy lemon background, you'll know you're making something truly wonderful.
Key Ingredients
- Fresh Blueberries: Frozen work too
- Fresh Lemons: Need both zest and juice
- Unsalted Butter: Softened
- Large Eggs: Softened
- Whole Milk: Adds softness
- All-Purpose Flour: Gives form
- Pure Vanilla Extract: Adds richness
- Baking Powder: Must be fresh
- Kosher Salt: Boosts taste
STEP-BY-STEP PREPARATION
- 1. Initial Setup:
- Heat oven to 350°F. Coat two 9-inch round pans with cooking spray and add parchment circles. Make sure ingredients aren't cold. Mix lemon zest with sugar until it smells amazing.
- 2. Cake Base:
- Mix butter with lemon sugar until fluffy and pale, about 3-4 minutes. Drop 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 plain batter in each pan first - this stops berries from dropping to the bottom. Mix 1 cup blueberries into leftover batter and split between pans. Scatter remaining berries on top.
- 4. Baking Process:
- Cook for 35-42 minutes until edges turn golden and toothpick comes out clean. Let sit in pans for 15 minutes, then move to cooling rack until fully cool.
- 5. Frosting Creation:
- Whip butter until creamy and light. Slowly add sifted powdered sugar, then lemon juice and vanilla. Beat until fluffy and smooth, about 4-5 minutes.

The magic happens in the small details. My baking teacher always told me, "A fantastic cake builds from the ground up, with each careful step making a difference."

Storage and Make-Ahead Success
Fix parts up to a day early: wrap plain cakes in plastic at room temp and keep frosting in the fridge. When it's time to put together, let frosting warm up and whip again if needed. The finished cake stays good in the fridge for 5 days, but tastes best when brought to room temperature before eating.
Temperature and Serving Variations
Enjoy at room temp when lemon tastes brightest and cake feels perfectly soft. In hot months, top with extra fresh berries and mint. For parties, add pretty edible flowers or candied lemon pieces. Make a sweet spread by serving alongside other fruit desserts.

Inventive Changes
Switch things up during berry season by trying different fruits like raspberries, blackberries, or mixed berries. Add a hint of almond flavoring to the mix, or blend in orange or lime zest for a different citrus kick. For fancy events, put lemon curd or berry jam between layers. While you can play around with the recipe, nothing beats the classic combo of lemon and blueberry for that real summer taste.
