This bakery-style blueberry layer cake is perfect for birthdays and special occasions. Incredibly moist and loaded with natural blueberry flavor, it features layers of homemade blueberry compote and a creamy blueberry buttercream.
This cake tastes like an extra-berry-rich, super-moist blueberry muffin transformed into a layer cake. Paired with homemade blueberry compote and a light blueberry buttercream, it’s a dream for blueberry lovers.
At Amycakes Bakery, this was a seasonal favorite—many customers requested blueberry birthday cakes year after year. Several people have told me it’s one of the best cakes they’ve tasted.

🥣 Key Ingredients
- Frozen blueberries are used for both the compote and the puree because they’re typically picked and frozen at peak ripeness, giving consistent flavor year-round. Frozen berries also release more juice when thawed, contributing to a moister cake.
- A blueberry emulsion (a concentrated, thicker extract) adds bright blueberry flavor without needing large amounts. If you use a different brand, add a little at a time and adjust to taste.
- A tiny amount of red liquid food coloring is optional to keep the crumb a more purple hue that matches the buttercream; without it the batter can lean blue-green from the eggs and butter.
- Buttermilk makes an exceptionally moist cake and balances the sweetness. For best results, follow measured gram weights when possible.
👩🏻🍳 Baking Tips
- This recipe uses a simple two-bowl method, so no stand mixer is required to make the batter. Preparing the compote and puree ahead of time speeds things up.
- If you need to split the work, make the blueberry compote and puree the day before and store them in the refrigerator.

💭 Frequently Asked Questions
Frozen blueberries are recommended because they provide consistent ripeness and juiciness. Fresh berries may work but could yield a slightly different texture and moisture level.
Yes. This cake freezes well. Freeze the fully assembled cake after filling and crumb-coating (or after finishing). Thaw overnight in the refrigerator, then bring to room temperature for 2–3 hours before serving for best texture.
Yes. Use a 2-oz (¼ cup) scoop to portion batter for about 17 cupcakes in a 1x batch. Bake at 350°F for 10 minutes, then reduce to 300°F for an additional 3–5 minutes. Make extra filling so you can core and fill the cupcakes.

Instructions
Prepare the blueberry compote filling and blueberry puree
- Prepare a 1x batch of the blueberry filling and allow it to cool. Reserve 70 grams (¼ cup) for the cake batter and hold the rest for filling the layers. The filling can be made a day ahead and refrigerated.
- Thaw the 170 grams of frozen blueberries and puree with their juices in a small food processor until smooth. Reserve about 78 grams (⅓ cup) for the buttercream and 78 grams (⅓ cup) for the cake batter. Keep the puree chilled until needed.
Bake the Blueberry Cake
- Preheat the oven to 325°F. Line a ¼ sheet pan with parchment and lightly spray the bottom and sides.
- Sift the dry ingredients and whisk to combine. In a separate bowl whisk the wet ingredients with the reserved 78 g (⅓ cup) blueberry puree. Pour the wet over the dry and whisk until combined.
- Stir in the reserved 70 g (¼ cup) blueberry compote. Pour in the melted salted butter and whisk until the batter is smooth and glossy.
- Spread batter evenly in the prepared sheet pan. Bake on the middle or upper rack at 325°F for 18 minutes, then reduce the oven to 300°F and bake 3–6 more minutes, or until a toothpick comes out mostly clean. Adjust time for larger batches or different ovens.
- Allow the cake to cool, then wrap it tightly in the pan and freeze at least 2 hours (up to 2 weeks). If freezing longer than a couple days, brush with simple syrup before wrapping (see notes).
Make the blueberry buttercream
- If using instant clearjel, whisk it into the powdered sugar and set aside.
- Beat the cream cheese until smooth. Add the room-temperature butter and beat until no lumps remain.
- Slowly add the powdered sugar mixture on low until incorporated. Add the vanilla, blueberry emulsion, and reserved blueberry puree. Scrape the bowl and then beat on high for 2–3 minutes to aerate and lighten the frosting. If you didn’t use clearjel, add up to 1 cup extra powdered sugar to reach desired thickness. The buttercream can be made 1–2 days ahead and refrigerated; bring it to spreadable temperature before decorating.
Layer, decorate and serve
- Cut cake layers from frozen or well-chilled cake using cake rings. Layer from frozen for easiest assembly; if serving the same day use chilled layers.
- Spread a ¼” layer of buttercream on the bottom layer, pipe a ½” tall ring of buttercream at the edge, and add blueberry filling inside the ring. Repeat for the second layer. Use remaining filling and buttercream to finish the cake.
- Apply a thin crumb coat and chill until firm, then add the final coat of buttercream. Optionally drizzle with white chocolate ganache and decorate with fresh blueberries. Refrigerate to set, then remove the cake 2–3 hours before serving to reach room temperature.
Notes
- Instant pudding mix contains modified cornstarch (similar to instant clearjel), which helps the cake stay moist. If you prefer, 1–2 tablespoons of instant clearjel may work in place of the pudding mix, though results may vary.
- I’ve tested this recipe using a blueberry emulsion; if you use a different extract, add it gradually and taste as you go.
- Red food coloring is optional and only used to nudge the crumb toward a purple hue that matches the buttercream.
- Simple syrup (1:1 sugar to water) can be brushed on cake layers before freezing or refrigerating for extended storage to help retain moisture.
