Raspberry Buttercream

Jump to Recipe Print Recipe

This is the best raspberry buttercream recipe made from real raspberries! Thick raspberry filling made from delicious fresh raspberries or frozen berries mixed into creamy easy vanilla buttercream frosting. It pairs perfectly with white chocolate raspberry cake, pink velvet cake, or lemon raspberry cake.raspberry buttercream on a vanilla cupcake

​​The trick to this raspberry buttercream frosting is getting the raspberry puree to the right consistency. The longer the berries are reduced, the thicker they will become and the more flavor will be concentrated. When raspberries are fresh, juicy, and warmed by the sun, there’s nothing like it, but frozen raspberries are a wonderful alternative that gives the same vibrant raspberry flavor.

Raspberries: If you have fresh berries available then this is a great way to use them and save that seasonal flavor. If not, frozen berries are just as good because they are picked at the peak of ripeness and flash-frozen. The freezing process starts to break down the berries, so as they thaw they will release their juices and break down quicker in the cooking process. Freeze-dried raspberries won’t work as well in this buttercream, because the butter will prevent the raspberries from rehydrating and releasing their flavor (and they are expensive).

Pasteurized Egg whites: Pasteurized egg whites are heat-treated (like milk) so they are safe to eat without cooking. They usually come in a box carton in the egg aisle. If you don’t have pasteurized egg whites then you can use my Swiss Meringue Buttercream recipe instead. 

Butter: Using good quality, real butter is best, but you can substitute it with margarine, vegan butter, or vegetable shortening. I can’t guarantee the taste will be the same, but you can use whatever is your preference! You can also mix the raspberry puree into any of my buttercream recipes, like Swiss meringue buttercream, American buttercream, and even cream cheese frosting.

FAQ

Would this be the same with other berries like blueberries or blackberries? 

Yes, follow the recipe the same way for other berries. You can choose to swap the lemon for lime or orange too for a different combination. 

How do you keep raspberry buttercream from splitting?

If the buttercream begins to separate, warm a little in the microwave and add it back to the batch, make sure you let it mix long enough to allow the puree to fully emulsify with the butter. 

Do I have to make raspberry filling or can I use store-bought? 

You can use raspberry jam or raspberry sauce from your local grocery store. However, store-bought won't have the same intense berry flavor as making it from frozen or fresh fruit. It will also contain more sugar, changing the flavor of the final product. 

Can you add fresh fruit to buttercream?

You don't want to add just straight-up chopped strawberries or raspberries to the buttercream. The best way to flavor buttercream with fruit is to cook the fruit into a puree first and pour that into your already prepared buttercream.
