This blueberry layer cake stands out with its rich textures and vibrant flavors. The combination of homemade blueberry jam and creamy buttercream creates a heavenly dessert experience. It’s ideal for celebrations or casual gatherings, bringing joy and sweetness to any table.
Key Ingredients for a Perfect Blueberry Cake
To create this delightful cake, you’ll need fresh or frozen blueberries, all-purpose flour, eggs, and a few other simple ingredients. Each component plays a crucial role in developing the cake’s luscious flavor and fluffy texture.
Crafting the Blueberry Jam
Ingredients for Blueberry Jam
- 16 oz fresh or frozen blueberries
- 1 ½ tablespoons lemon juice
- 1 teaspoon vanilla extract
- 1 cup granulated sugar
- Pinch of salt
Step-by-Step Blueberry Jam Instructions
Start by combining blueberries, lemon juice, vanilla, sugar, and salt in a saucepan. Cook over medium heat for 20-30 minutes, stirring frequently. Use a whisk or immersion blender to mash the blueberries for a smoother texture. Once thickened, remove from heat and refrigerate to cool.
Baking Fluffy Blueberry Cake Layers
Essential Cake Layer Ingredients
- 2 cups all-purpose flour (240g)
- ½ teaspoon salt
- 2 ½ teaspoons baking powder
- 4 large eggs (room temperature)
- 1 ½ cups granulated sugar (300g)
- ½ cup unsalted butter (115g)
- 1 cup whole milk
- 3 teaspoons vanilla bean paste or extract
- 3 teaspoons neutral oil (e.g., grapeseed or vegetable)
Preparing the Cake Batter
Preheat your oven to 350°F (175°C). Grease two 8-inch cake pans and line the bottoms with parchment paper. In a bowl, whisk together flour, salt, and baking powder, then set aside. Beat the eggs on medium speed for one minute, then gradually add sugar. Beat on high for about seven minutes until light and fluffy.
Assembling the Layered Batter
In a saucepan, gently heat the milk and butter until melted but not simmering. Combine the flour mixture with the egg mixture in three parts, mixing until just combined. Whisk in the warm milk-butter mixture, ensuring everything is well incorporated. For color, remove one-third of the batter, mix in ⅓ cup of blueberry jam, and add food coloring if desired.
Baking and Cooling the Cake Layers
Layer the batters into the pans, alternating between vanilla and blueberry. Swirl lightly with a knife. Bake for 25-30 minutes or until a toothpick comes out clean. Allow the cakes to cool in the pans for 15 minutes before inverting onto a cooling rack.
Creating the Blueberry Ermine Buttercream
Ingredients for Blueberry Ermine Buttercream
- 2 oz freeze-dried blueberries (ground to powder and sifted)
- 10.5 oz white granulated sugar (300g)
- 2.25 oz flour (65g)
- 12 oz whole milk
- 4 oz cream cheese (softened)
- 12 oz butter
- 1 ½ teaspoons vanilla
- ¾ teaspoon salt
- White chocolate (optional, for fixing frosting)
Making the Frosting Base
In a saucepan, combine flour and sugar, cooking over medium heat for two minutes while whisking constantly. Add blueberry powder and whisk before slowly incorporating milk. Bring to a simmer, whisking until thick and pudding-like. Transfer to a bowl and cover with plastic wrap to cool completely.
Whipping the Creamy Buttercream
Beat softened butter on high speed for three minutes until light and fluffy. Whip softened cream cheese briefly, then mix it into the butter. Gradually add the cooled flour mixture, ensuring a smooth consistency. Finish by adding vanilla and salt.
Assembling and Decorating Your Blueberry Layer Cake
Frosting Techniques: Crumb Coat and Final Layer
Begin by placing a small dollop of frosting on a cake board. Set one cake layer on top, cover with frosting, and then add the second layer. Apply a thick layer of frosting over the top and sides as a crumb coat. Chill for 10 minutes in the freezer or 30 minutes in the fridge to set.
Decorating Ideas
Once chilled, add the final layer of frosting, smoothing it out. Decorate with remaining frosting and fresh blueberries. Drizzle extra blueberry jam over the top for an extra touch of sweetness.
Tips for Blueberry Layer Cake Success
Fixing Grainy or Curdled Buttercream
If your buttercream becomes grainy, don’t worry! Simply melt and cool white chocolate, adding 50 grams for every 200 grams of frosting to restore its smooth texture.
Flavor Variations and Substitutions
You can add a layer of lemon curd between the cake layers for a zesty twist. Substitute fresh for frozen blueberries in the jam, and opt for vanilla bean paste instead of extract if you prefer.
Storage Instructions
Store leftover blueberry layer cake in the refrigerator. The homemade jam can last in the fridge for a while, ensuring you maintain the freshness of your delightful cake.

Instructions
- Prepare the blueberry jam by combining blueberries, lemon juice, vanilla, sugar, and salt in a saucepan. Cook for 20-30 minutes until thickened, mashing blueberries for a smoother texture. Refrigerate to cool and thicken.
- Preheat oven to 350°F (175°C) and prepare two 8-inch cake pans. Whisk together flour, salt, and baking powder. Beat eggs and sugar until light and fluffy.
- Gently heat milk and butter until melted but not simmering. Do not cool completely.
- Add dry ingredients to the egg mixture in three parts, mixing until almost combined. Whisk vanilla and oil into the warm milk-butter mixture. Temper the milk mixture by adding a couple of spoonfuls of egg batter, then combine both mixtures on low speed.
- Divide one-third of the batter into a separate bowl. Mix in ⅓ cup of cooled blueberry jam and food coloring if desired.
- Layer the batters into the prepared pans (vanilla, blueberry, vanilla) and swirl lightly. Bake for 25-30 minutes until a toothpick comes out clean. Cool in pans for 15 minutes before inverting onto a rack.
- For the frosting base, combine flour and sugar in a saucepan and cook for 2 minutes. Whisk in blueberry powder and milk, then bring to a simmer until thick and pudding-like. Cook for 1 minute more, then cool completely.
- Beat softened butter until fluffy. Briefly whip softened cream cheese to remove lumps and add to the butter. Gradually add the cooled flour mixture, vanilla, and salt, mixing until smooth and incorporated.
- Assemble the cake by frosting each layer and the outside. Apply a thin crumb coat, chill for 10-30 minutes, then apply the final frosting layer. Decorate as desired with remaining frosting and fresh blueberries.
Notes
- If the buttercream becomes grainy, add 50g of melted white chocolate per 200g of frosting to restore consistency. The blueberry batter layer may sink, which is normal and does not affect flavor.
- Consider adding a layer of lemon curd between cake layers or placing blueberry jam between layers instead of on top for variations. Ensure the frosting base is completely cool before adding butter.
