Key Ingredients for a Moist, Flavorful Cake

For this recipe, we use frozen blueberries for both the homemade blueberry compote and blueberry purée. Frozen fruit is typically picked at its peak ripeness, which ensures the best flavor year-round. Additionally, frozen blueberries tend to be juicier than fresh ones, helping to make the cake extra moist.

We also use Olive Nation blueberry emulsion in this recipe because it delivers a fresh, pure blueberry flavor. An emulsion is similar to an extract but thicker and more concentrated, so you don’t need to use as much to get that fresh blueberry taste. We’ve used Olive Nation products since the start of our bakery and trust their quality. You can save 20% on their website with the code AB20 (thank you for your support!). If you prefer to use a different blueberry extract or emulsion, feel free to adjust the amount to taste.

A tiny bit of red food coloring is optional and helps give the cake a more purple hue to match the naturally purple blueberry buttercream. Without it, the cake will have more of a blue-green or seafoam shade due to the yellow from eggs and butter.

We also swear by using buttermilk for an extra-moist cake. It balances the sweetness and gives the cake an incredibly soft crumb. If you want to learn more about why buttermilk works wonders in cakes, check out our article on Seven Bakery Secrets to Incredibly Moist Cakes.

Frequently Asked Questions

Can you use fresh blueberries instead of frozen?

We haven’t tried using fresh blueberries in this recipe because we love the juiciness and flavor that frozen blueberries provide. Frozen berries tend to yield a moister, more flavorful cake.

Can you freeze this blueberry layer cake?

Yes! This cake freezes wonderfully, making it perfect for preparing ahead of time. We recommend freezing the entire cake once it’s filled and either crumb-coated or fully frosted, as outlined in How to Bake and Layer Cakes Like a Pro. When you’re ready to serve, thaw the cake overnight in the refrigerator, then remove it 2–3 hours before serving to bring it to room temperature. You’ll never know it was frozen—this cake is so moist!

Can you turn this recipe into blueberry cupcakes?

Absolutely! This recipe makes delicious blueberry cupcakes. Use a 2-ounce scoop (about ¼ cup) to divide the batter into 17 cupcakes. Bake at 350°F for 10 minutes, then reduce the oven temperature to 300°F and bake for another 3–5 minutes until a toothpick comes out clean.

To fill the cupcakes, we recommend making a larger batch of the blueberry filling. You can easily use a cupcake corer to add the filling to the center of each cupcake.

This blueberry cake is the perfect treat for any occasion—whether you're celebrating a birthday or simply indulging in your love of blueberries. With its rich blueberry flavor, moist texture, and decadent layers of filling and frosting, it’s a showstopper that’s sure to impress.
