The ultimate blueberry buttercream recipe

If you’re looking for a delicious and creamy blueberry frosting, then you must try this recipe. It’s so easy with just 4 ingredients AND is perfectly smooth- no splitting buttercream here!

This is my all time favorite frosting recipe to add to my spring cakes- especially my vegan lemon blueberry cake. In fact, this frosting recipe is so good, it’s in my first cookbook

You can even swap it in for my chocolate frosting on my chocolate cake, my vanilla buttercream on this vegan vanilla cake, or even swap it in for my peanut butter frosting on this banana cake (because bananas and blueberries go so well together!). 

We’re using fresh blueberry jam (not blueberry sauce!) to create a vibrant and rich purple-pink color with a fresh blueberry flavor throughout. No artificial flavors, no blueberry powders. Just the real deal!

And plus, I’m going to go over all of the tips to help you make this blueberry frosting recipe perfectly each time, including how to properly bring your butter to room temperature and why a frosting might split (especially if you’re using a fruit spread!). 

And if you love cream cheese frosting, you can actually turn this into a blueberry cream cheese frosting too!

4 Ingredients Needed:

  • Vegan butter: I recommend a high quality vegan butter, such as Miyoko’s. It’s fantastic for frostings and vegan baking in general. You can also swap in half of the vegan butter amount for vegan cream cheese if you want a bit more of a tang! The key here is to use room temperature butter. Check out my guide for getting your butter to room temperature properly here!
  • Powdered sugar: Again, a high quality powdered sugar is key! Also make sure that you’re using organic/vegan-certified, like Florida Crystals. 
  • Blueberry jam: I recommend using homemade blueberry jam. It’s what I use to get that super pink and lovely color. Store bought blueberry jam will give you more of that purple color at times, depending on the brand. Either works, so use whichever makes most sense for you! You can also use this recipe as the base for another berry frosting, like this blackberry cream cheese frosting in my blackberry lavender cake!
  • Vanilla extract: Just a touch to round out the flavor!

Step-by-Step How to Make Blueberry Frosting

Help!! My frosting is splitting!

Usually, it’s very hard to recover a split buttercream frosting. However, we can actually do some saving here if this happens to your frosting!

If you notice your blueberry frosting starts to split, you can add in another 1/2 cup- 1 cup of powdered sugar. This will help absorb the liquid in the frosting and return it to that fluffy and smooth spreadable consistency. 

If you’re really worried about splitting, however, you can use freeze dried blueberries and blitz them into a powder, like in my vegan strawberry buttercream frosting!
