Raspberry Buttercream Frosting – Fresh or Frozen Berries

If you eat cake for the frosting – then this raspberry buttercream is a definite must. It’s creamy and fluffy with a delicious natural raspberry flavor. It can be made with fresh berries when they’re in season, or frozen raspberries. The pink color looks beautiful, but it’s the fresh raspberry flavor that you’ll really love!

I absolutely love buttercream frosting. I’m a bit of a buttercream addict. A frosting aficionado if you will.

Not that grossly sweet, slightly oily stuff you find on grocery story cakes. But creamy, fluffy, deliciously smooth buttercream frosting.

And if you’re a person that mainly eats cake for the frosting too – then let’s be best friends. Seriously, we’ve got a lot of delicious baking & eating ahead of us.

So today, we’re making this delicious raspberry buttercream frosting. Everyone seemed to love this Strawberry Buttercream Frosting – so I figured it was time to make a raspberry version just in time for summer and all the fresh berries coming into season. 

It’s fluffy, creamy, smooth – and it has the most delicious natural raspberry flavor and bright pink color. I love it on vanilla cake, chocolate cake, or really just about anything. You’re going to die a happy frosting induced death.

Now, for this recipe – it works totally fine whether you make raspberry frosting with fresh berries or raspberry frosting with frozen berries.

To get started, first the raspberries are processed in a blender or food processor. I have a Magic Bullet, which I LOVE. Since there’s only 2 people in our house it’s the perfect size. Plus, it’s way easier cleanup than having a huge blender. But I’ve also heard awesome things about a Vitamix.

Here’s the raspberry puree. You’ll likely end up with about 2/3 to 1 cup, depending on if you use fresh or frozen berries.

Then we push it through a metal sieve to remove the seeds. This process is a little annoying (think sifting icing sugar) – but using a rubber spatula to push it through works just great.

Then we gently boil the raspberry puree for a good 10-20 minutes to remove excess water. When it’s done, you should end up with about 3-4 tablespoons of thick raspberry sauce. The more you reduce the raspberry puree, the thicker and more pipe-able your frosting will be.

Then the reduced puree gets chilled in the fridge or freezer. I cannot stress enough the importance of the puree being cold when it’s added to the butter to make your frosting. If it’s still even the tiniest bit warm, the whole frosting will separate 🙁 🙁 🙁

After we’ve made the raspberry puree and reduced it to a thick jam-like consistency, making the frosting is like your typical buttercream.

1. Beat the butter until fluffy.
2. Mix in the sifted powdered sugar.
3. Then add in the cooled raspberry puree.
4. And finally beat in the rest of the powdered sugar and a little whipping cream if needed.

This raspberry buttercream frosting is always delicious – whether you choose to pipe it onto cupcakes or frost a thin layer on sheet cake. It’s creamy, dreamy & delicious. And the raspberry flavor makes it way more special than just coloring the frosting with food coloring.

Seriously, if you want to take your cake or cupcakes to the next level – then this Raspberry Buttercream Frosting is for you!
