Ingredients for Your Lemon Blueberry Breakfast Cake
- 1/2 cup unsalted butter, softened (this really makes a difference for creaming!)
- 1 tablespoon lemon zest (get all those fragrant oils from the peel!)
- 2 tablespoons fresh lemon juice (for that zippy brightness)
- 1 cup granulated sugar (for sweetness and a tender crumb)
- 1 large egg (at room temperature is best)
- 2 teaspoons vanilla extract (because vanilla makes everything better)
- 1 3/4 cups all-purpose flour (start with this, we’ll toss the berries in a bit more later)
- 2 teaspoons baking powder (our lift agent!)
- 1/2 teaspoon salt (to balance the sweetness)
- 2/3 cup buttermilk (this is key for that super moist texture!)
- 2 cups fresh blueberries (mine are usually plump and ready to go from the farmer’s market!)
Step-by-Step Instructions for the Perfect Lemon Blueberry Breakfast Cake
Okay, let’s get baking! First things first, preheat your oven to 350 degrees F. This is super important so your cake bakes evenly. Then, grab your 9 x 9 inch baking dish and give it a good grease. I usually use a little butter and a dusting of flour, or even just a good spray. No one wants their cake stuck!
Now for the good stuff! In a nice big mixing bowl, we’re going to cream together the softened butter, that lovely lemon zest we zested, the fresh lemon juice, and the sugar. Beat it until it’s all light and fluffy – you’ll see it get nice and pale. This is where we build that tender crumb!
Next, add in your egg and the vanilla extract. Give that another good mix until everything is totally combined. Don’t overmix, just until it’s happy together.
In a separate, smaller bowl, whisk together your flour, baking powder, and salt. This little step ensures your baking powder and salt are perfectly distributed, so you won’t get any weird salty surprises!
Here’s where we bring it all together. Gradually add the dry ingredients to your wet ingredients, but alternate it with the buttermilk. So, a little dry, mix, a little buttermilk, mix, another bit of dry, mix, and so on. Just stir until you have a nice, smooth batter. It shouldn’t be too thick or too thin, just… right!
For the blueberries, I like to toss them with about 2 tablespoons of flour right in the bowl before I add them to the batter. This tiny trick helps prevent them from all sinking to the bottom like little blue rocks. Trust me on this one!
Gently fold those flour-coated blueberries into your batter. I like to use a spatula for this, just coaxing them in so you don’t break them up too much. We want those beautiful pops of color and flavor!
Spread that gorgeous batter evenly into your prepared baking dish. Make sure it’s a nice, even layer so it bakes up beautifully.
Pop it into your preheated oven and bake for about 35 to 40 minutes. You’ll know it’s ready when the top is lightly golden and a toothpick you stick in the center comes out clean. No gooey batter clinging to it!

Now, this is the hardest part – waiting! Let the cake cool in the dish for about 10 minutes before you try to slice into it. This helps it set up properly. If you’re feeling impatient, you can always just grab a spoon and dig into the edge! 😉 You could also try making these super easy air fryer donuts while you wait!
Serving Suggestions for Your Lemon Blueberry Breakfast Cake
This cake is pretty perfect on its own, but sometimes you just want to jazz things up a bit! Here are a couple of my favorite ways to serve it:
A Dollop of Cream Cheese Frosting: Just a little bit of sweet, tangy cream cheese frosting takes this cake to another level. It’s like a mini cheesecake in cake form!
Fresh Berries and Whipped Cream: Because who doesn’t love *more* berries? Pile some fresh raspberries or strawberries next to a slice and top with a cloud of whipped cream. So pretty! You could even try a peach caprese salad for a sweet and savory twist.
A Side of Guacamole: If you want something lighter, a bright and refreshing fruit salad is a lovely contrast. Or, if you’re feeling savory, a simple guacamole is a surprisingly delightful pairing with the tartness of the cake!

Storing and Reheating Your Lemon Blueberry Breakfast Cake
Don’t you hate it when you have a little leftover cake and you’re not sure what to do with it? No worries! I usually just wrap my Lemon Blueberry Breakfast Cake tightly in plastic wrap or pop it into an airtight container. It’ll keep nicely in the fridge for up to 3 days. Honestly, it tastes just as good, if not better, the next day!
Reheating is super simple. If you want that fresh-from-the-oven warmth, just pop a slice into the microwave for about 15-20 seconds. It’s perfect for a quick morning reheat! For a slightly crisper edge, you can even warm it up in a toaster oven at 300°F for a few minutes, but be careful not to let it dry out.
Frequently Asked Questions About This Lemon Blueberry Breakfast Cake Recipe
Can I use frozen blueberries instead of fresh?
Absolutely! You can totally use frozen blueberries. Just make sure you don’t thaw them first. Toss them in the flour just like you would the fresh ones. It helps prevent them from turning your batter into a blue mush. They might create a bit more steam when baking, so keep an eye on it, but it works like a charm!
What can I substitute for buttermilk?
No buttermilk? No problem! My go-to substitute is super easy: just take 2/3 cup of regular milk and stir in 2/3 tablespoon of lemon juice or white vinegar. Let it sit for about 5 minutes until it looks a little curdled. It acts just like buttermilk and gives you that amazing tender crumb. You could also try using plain yogurt thinned with a little milk!
How can I make this cake lemonier?
Oh, I love that question! For an extra lemony punch, you can do a couple of things. First, add another teaspoon of lemon zest to the batter along with the original tablespoon. Second, after the cake is baked and while it’s still warm (but not piping hot!), you can make a simple lemon glaze. Just whisk together about 1/2 cup of powdered sugar with 1-2 tablespoons of lemon juice until it’s smooth and a nice drizzling consistency. Drizzle that over the warm cake and let it soak in. It’s divine! You can also check out my Lemon Blueberry Pound Cake or try making some Blueberry Lemon Overnight Oats for more of that amazing flavor combination.
