What Is Blueberry Swirl Cake?

Think of this as your favorite vanilla cake’s much more interesting cousin!

What You’ll Need for This Blueberry Swirl Cake

I love how this recipe uses simple pantry staples that you probably already have on hand. Moreover, the ingredient list isn’t overwhelming, which means you can whip this up on a weekend afternoon without making a special grocery run.

• All-purpose flour (2 cups) – The foundation of our cake. You can substitute with cake flour for extra tenderness
• Granulated sugar (1 cup) – Sweetens the batter perfectly. Brown sugar works too for deeper flavor
• Unsalted butter (1/2 cup, softened) – Creates that rich, moist texture we’re after
• Large eggs (3 whole) – Adds structure and helps bind everything together beautifully
• Vanilla extract (2 teaspoons) – Because vanilla makes everything better, honestly
• Baking powder (2 teaspoons) – Our leavening agent for that perfect rise
• Salt (1/2 teaspoon) – Balances the sweetness and brings out all the flavors
• Whole milk (3/4 cup) – Keeps the cake incredibly moist. Buttermilk works great too
• Fresh blueberries (1 1/2 cups) – The star of the show! Frozen works if that’s what you have
• Powdered sugar (1/4 cup) – For the blueberry swirl mixture
• Lemon juice (1 tablespoon) – Brightens up the blueberry flavor amazingly

Step-by-Step Instructions

Prep Your Kitchen: First, preheat your oven to 350°F and generously grease a 9-inch round cake pan. Then, lightly dust it with flour to prevent sticking. Trust me, this step saves so much heartache later!

Make the Blueberry Mixture: Meanwhile, mash about half of your blueberries with powdered sugar and lemon juice in a small bowl. Leave some berries whole for texture. This creates that gorgeous swirl we’re going for in our blueberry swirl cake.

Cream Butter and Sugar: In a large bowl, beat softened butter with granulated sugar until light and fluffy. This usually takes about 3-4 minutes with an electric mixer. Subsequently, add eggs one at a time, beating well after each addition.

Combine Dry Ingredients: In another bowl, whisk together flour, baking powder, and salt. This ensures even distribution throughout your blueberry swirl cake batter.

Bring It All Together: Alternately add the flour mixture and milk to your butter mixture. Start and end with flour mixture. Mix just until combined because overmixing leads to tough cake texture.

Create the Swirl: Pour half the batter into your prepared pan. Then, dollop spoonfuls of the blueberry mixture over the batter. Add remaining cake batter on top, followed by more blueberry mixture.

Swirl Magic: Using a knife or skewer, gently swirl through the batter to create that beautiful marbled pattern. Don’t overdo it though – a few gentle swirls create the prettiest effect.

Bake to Perfection: Finally, bake for 45-50 minutes until a toothpick inserted in the center comes out with just a few moist crumbs. Cool in the pan for 10 minutes before turning out onto a wire rack.

Perfect Serving Ideas

This blueberry swirl cake is absolutely divine on its own, but there are so many ways to dress it up! Additionally, I love serving it with a dollop of freshly whipped cream or a scoop of vanilla ice cream. Furthermore, a light dusting of powdered sugar makes it look bakery-perfect for special occasions.

Tips For The Perfect Blueberry Swirl Cake

• Room temperature ingredients: Let your eggs, butter, and milk come to room temperature for the smoothest batter
• Don’t overmix: Stop mixing as soon as the flour disappears to keep your cake tender
• Toss berries in flour: Coating fresh blueberries in a little flour prevents them from sinking
• Test for doneness: The cake should spring back lightly when touched in the center
• Cool completely: Wait until the cake is totally cool before slicing for clean cuts
• Storage tip: Cover tightly and store at room temperature for up to three days

Frequently Asked Questions

Can I use frozen blueberries in this blueberry swirl cake? Absolutely! Just don’t thaw them first. Toss the frozen berries in a little flour and fold them right into the batter. They might add a few extra minutes to your baking time.

How do I prevent the swirl from disappearing? The key is not overmixing when you create the swirl pattern. Also, make sure your blueberry mixture isn’t too thin. A thicker consistency holds its shape better during baking.

Can I make this cake ahead of time? Yes! This blueberry swirl cake actually tastes even better the next day. The flavors meld together beautifully overnight. Just wrap it tightly in plastic wrap and store at room temperature.

What size pan should I use? I recommend a 9-inch round pan for the perfect thickness. However, you could also use an 8×8 square pan if that’s what you have. Just adjust the baking time accordingly.
