What Ingredients are in Blueberry Swirl Coffee Cake?
This delicious coffee cake comes together with simple pantry staples and that gorgeous blueberry jam for the perfect morning treat.
- 2 cups all-purpose flour
- 1 cup granulated sugar
- 2 teaspoons baking powder
- 1/2 teaspoon salt
- 1/2 cup butter, softened
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup milk
- 1/2 cup blueberry jam
For the best results, make sure your butter, eggs, and milk are all at room temperature—cold ingredients just don’t play well together and can leave you with a lumpy batter instead of that velvety smooth texture we’re after.
How to Make this Blueberry Swirl Coffee Cake
Step 1: Prepare Your Baking Pan
Grease and flour a 9-inch round cake pan or 8×8 square baking dish, then preheat your oven to 350°F.
Nothing worse than finishing your batter only to realize you haven’t even turned on the oven yet—been there, done that.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together 2 cups all-purpose flour, 2 teaspoons baking powder, and 1/2 teaspoon salt until well combined.
This quick step guarantees your leavening agents are evenly distributed throughout the flour, giving your cake that perfect rise.
Step 3: Cream Butter and Sugar
In a large mixing bowl, beat 1/2 cup softened butter and 1 cup granulated sugar until light and fluffy, about 2-3 minutes.
This creaming process incorporates air into the batter, which means a lighter, more tender cake—totally worth the arm workout.
Using a quality stand mixer makes the creaming process much easier and ensures consistently smooth results.
Step 4: Add Eggs and Vanilla
Add 2 large eggs one at a time, beating well after each addition, then mix in 1 teaspoon vanilla extract.
The mixture might look a bit curdled at this stage, but don’t panic, it’ll all come together once we add the dry ingredients.
Step 5: Alternate Adding Dry Ingredients and Milk
Gradually add the flour mixture to the butter mixture, alternating with 1/2 cup milk, beginning and ending with the flour.
Mix just until combined after each addition—overmixing is the sworn enemy of tender cake.
Step 6: Create the Blueberry Swirl
Spread half the batter into your prepared pan, then dollop 1/2 cup blueberry jam over the surface.
Using a knife, gently swirl the jam through the batter for that gorgeous marbled effect.
Spoon the remaining batter on top, spreading carefully to cover the jam layer.
Step 7: Bake to Golden Perfection
Bake in your preheated oven for 40-45 minutes, or until a toothpick inserted in the center comes out clean with just a few moist crumbs.
The house will smell absolutely divine as the cake bakes—fair warning, your neighbors might “coincidentally” drop by.
Step 8: Cool Before Serving
Allow the cake to cool in the pan for about 15 minutes, then transfer to a wire rack to cool completely before slicing.
I know it’s tempting to dig in right away, but trust me, letting it cool properly means those beautiful swirls will hold their shape when you cut into it.
What to Serve with Blueberry Swirl Coffee Cake
This coffee cake is the star of any breakfast or brunch spread, but a few perfect pairings really make it shine. A dollop of lightly whipped cream or vanilla yogurt adds a cool, creamy contrast to the sweet blueberry swirls.
For morning gatherings, serve alongside a fresh fruit salad—think strawberries, pineapple, and mint—to balance the richness.
Coffee is the obvious beverage match (it’s in the name, after all), but don’t underestimate how wonderful this cake tastes with a steaming cup of Earl Grey or a frothy cappuccino.
Want something more substantial? A side of crispy bacon provides that sweet-savory combo that makes weekend brunches so irresistible.
And if you’re feeling fancy, warm a little extra blueberry jam to drizzle over each slice.
Blueberry Swirl Coffee Cake Substitutions and Variations
- Texture Add-Ins: Sprinkle ¼ cup chopped nuts (walnuts or pecans) between the batter layers or mix in ½ cup fresh blueberries.
- Topping Ideas: Dust with powdered sugar before serving, or drizzle with a simple glaze (½ cup powdered sugar + 1 tablespoon milk + drop of vanilla).
- Spice It Up: A pinch of cardamom or cinnamon in the batter works wonders with the blueberry flavor.
Leftovers and Storage for this Blueberry Swirl Coffee Cake
This coffee cake stays remarkably moist for days, making it perfect for busy weekends when you want something delicious on hand.
- Counter Storage: Store in an airtight container at room temperature for up to 2 days.
- Refrigeration: Keep in the fridge for up to 5 days in a sealed container.
- Freezer Option: Wrap individual slices tightly in plastic wrap, then foil, and freeze for up to 3 months.
To refresh, microwave refrigerated slices for 15-20 seconds or let frozen pieces thaw overnight in the refrigerator. A quick 5-second warm-up brings back that just-baked texture.
Many folks (myself included) think this cake actually tastes even better on day two, when the blueberry flavor has fully permeated the tender crumb.
Final Thoughts
This Blueberry Swirl Coffee Cake strikes that perfect balance between elegance and comfort—tender crumb meeting ribbons of sweet-tart blueberry in every bite.
It’s the kind of recipe that makes even ordinary mornings feel special, yet requires no fancy techniques or hard-to-find ingredients. Perfect for weekend brunches when you want something homemade but don’t want to spend all morning in the kitchen, or as a thoughtful offering when friends drop by unexpectedly.
