Easy Lemon Blueberry Cake with Cream Cheese Frosting

I get so excited when I pull out a recipe that feels bright, fresh, and a little bit special, and this lemon blueberry cake always hits that sweet spot. It’s the kind of dessert that instantly lifts the mood with its sunny lemon flavor and bursts of juicy blueberries in every slice. I like to keep things simple in my kitchen, and this one comes together without any fuss, which makes it perfect for busy days or those last-minute cravings for something homemade.

As the cake bakes, the whole kitchen fills with the scent of warm lemon and butter, and that’s honestly one of my favorite parts. The batter is quick to mix, the ingredients are easy to find, and there’s no complicated decorating to worry about. It’s a great option for potlucks, Sunday dinners, or just a quiet afternoon when you want a little treat that feels comforting and refreshing at the same time.

And then there’s the cream cheese frosting. It’s creamy, lightly tangy, and pairs so well with the lemony cake that I could happily eat it with a spoon. Once everything is cooled and frosted, the cake looks beautiful without any effort at all. It’s one of those recipes I reach for whenever I want something that feels homemade and heartfelt without spending hours in the kitchen.

Ingredients

For the Cake:

• 1 ⅔ cups all-purpose flour (200 g): This gives the cake its soft, tender structure.

• 1 tsp baking powder: Helps the cake rise so it turns out light and fluffy.

• ¼ tsp baking soda: Adds an extra lift and balances the acidity from the lemon and buttermilk.

• ¼ tsp salt: Enhances all the bright citrus and berry flavors.

• ½ cup unsalted butter, room temperature (100 g): Creams beautifully with the sugar for a rich, buttery crumb.

• ¾ cup granulated sugar (150 g): Sweetens the cake without overpowering the lemon.

• 2 large eggs: Bind everything together and add moisture.

• ½ cup buttermilk or plain yogurt (120 ml): Keeps the cake extra moist and adds a subtle tang.

• 1 tsp vanilla extract: Rounds out the flavors with a warm, sweet note.

• 1 tbsp lemon zest: Adds that fresh citrus brightness in every bite.

• 1 cup blueberries, fresh or frozen (150 g): Brings juicy bursts of flavor and beautiful pops of color.

For the Frosting:

• ½ cup unsalted butter, softened (100 g): Creates a smooth, creamy base for the frosting.

• 7 oz brick-style cream cheese (200 g): Adds a tangy richness that pairs perfectly with lemon.

• 2 cups powdered sugar, sifted (200 g): Sweetens the frosting and makes it fluffy and smooth.

• 2 tsp fresh lemon juice: Brightens the frosting with a fresh citrus twist.

Tips & Tricks for the Perfect Lemon Blueberry Cake

• Toss the blueberries in a spoonful of flour before folding them into the batter to keep them from sinking.

• Make sure the butter is truly at room temperature so it creams smoothly with the sugar.

• Use fresh lemon zest rather than bottled lemon flavoring for the best citrus punch.

• Don’t overmix the batter once the dry ingredients go in, or the cake can turn dense.

• If using frozen blueberries, add them straight from the freezer to prevent streaking.

• Check the cake a few minutes early, since every oven runs a bit differently.

• Let the cake cool completely before adding the frosting so it stays thick and creamy.

• For an extra pop of lemon, add a little more zest to the frosting or sprinkle some on top.

• Line the pan with parchment to make lifting the cake out easier and cleaner.

Serving

• Slice and serve at room temperature so the frosting stays soft and creamy.

• Add a handful of fresh blueberries or a sprinkle of lemon zest on top for a pretty presentation.

• Pair each slice with a cup of tea, iced coffee, or a light herbal drink for a cozy treat.

• Serve it chilled for a firmer, refreshing texture on warmer days.

• Cut into small squares for a dessert table or potluck to make sharing easy.

Storing

• Keep the cake covered in the fridge for up to 4 days to maintain its freshness.

• Store individual slices in airtight containers to keep them from drying out.

• Let refrigerated slices sit at room temperature for a few minutes before serving so the frosting softens.

• Freeze unfrosted cake layers tightly wrapped for up to 2 months, then thaw before frosting.

• If you freeze finished slices, wrap them well and thaw in the fridge for an easy make-ahead treat.

FAQs

Can I use frozen blueberries instead of fresh?

Yes, frozen works great. Just add them straight from the freezer so they don’t bleed into the batter.

Can I make this cake ahead of time?

Absolutely. You can bake the cake a day in advance and frost it once it has fully cooled.

What can I use instead of buttermilk?

Plain yogurt works perfectly, or you can make a quick substitute by mixing milk with a little lemon juice.

How do I keep the blueberries from sinking?

Toss them in a spoonful of flour before folding them into the batter to help them stay evenly distributed.

Can I bake this in a different size pan?

Yes, an 8-inch round or square pan works well, but you can also use a 9-inch pan; just reduce the baking time slightly.

Does the cake need to be refrigerated?

Because of the cream cheese frosting, it’s best to store the cake in the fridge.

Can I skip the frosting?

You can. The cake tastes delicious on its own, and a dusting of powdered sugar is a simple alternative.

Can I double the recipe?
