This Lemon Blueberry Cake baked in a cast iron skillet is a delightful fusion of zesty citrus and sweet, juicy blueberries, offering a rustic yet elegant dessert or brunch treat.
The cake’s bright lemon flavor perfectly complements the bursts of blueberries scattered throughout. Cooking it in a cast iron skillet gives the edges a subtle crispness while keeping the center moist and fluffy.
The simple lemon glaze on top is the perfect, final touch.
I absolutely love blueberries. I especially loved picking the wild ones when we lived up in Alaska.
I mean, can you imagine sitting out on the tundra, surrounded by majestic wilderness, and picking berries until your heart’s content?
We would visit this area several times during the summer. First, to pick the wild blueberries.
Then after the first frost, we would come back and fill our baskets with wild cranberries.
It was heaven.
I may not be in the wilds of Alaska anymore, but I can still certainly enjoy the flavor of blueberries. Today’s citrus theme combines two things that I love – lemon and blueberry. They complement each other perfectly in this simple cake.

Make the Lemon Blueberry Skillet Cake
To begin, preheat your oven to 350°(F).
In a medium bowl, combine all-purpose flour with baking powder and salt. Give it a stir and set it aside.
In your mixing bowl, beat together room temperature, unsalted butter and granulated sugar. Beat them until fluffy. Add in three room temperature eggs, one at a time, mixing each in completely before adding the next.
Zest part of a lemon, enough to give you 1 teaspoon of zest. Reserve the lemon. Add the zest and a teaspoon of vanilla extract to the cream mixture. Mix it in.
Add half of the flour mixture into the cream mixture, scraping the sides of the bowl with a rubber spatula. Next, mix in sour cream. Once that is mixed in, add the remaining flour mixture.

Each time you add something, scrape the bowl with a rubber spatula to get everything combined and only mix it enough to blend the ingredients together.
Gently fold in fresh, clean blueberries.
Spray a 9-inch cast iron skillet with baking spray or non-stick cooking spray. I prefer the baking spray with the flour in it.
Spread the batter into the prepared skillet.
Sprinkle the top with another 1/4 cup of blueberries and gently press them into the batter.
Bake for 30-35 minutes or until a wooden pick inserted into the center comes out clean. Place the skillet on a rack for the cake to cool.
When the cake is cooled, you will prepare the simple glaze.
Make the Lemon Glaze
Using the lemon you reserved from earlier, combine juice from the lemon with powdered sugar and vanilla extract. Whisk these together until smooth. Drizzle the glaze over the top of the cake.
You will absolutely love how the lemon and blueberry flavors sing together in this cake.
This is an excellent cake to serve at brunch with coffee. Enjoy!
