Blackberry Buttercream Frosting With Real Blackberries, No Straining Required

By Olya Shepard · Baker: Layer Cakes, Cookies & Desserts

Blackberries win my favorite-fruit vote every summer, wild ones especially. I once went camping and found a ten-foot wall of blackberry bushes right nearby, and I spent a solid two hours gorging on them until my hands and face were sticky with red juice. This frosting is my way of getting that real blackberry flavor into buttercream, no extract, no straining, just fruit beaten straight into the mix.

🍇 I'm officially making this blackberry frosting all summer long, and skipping the straining step is what makes it fast enough to actually do that. My trick is to choose ripe but not mushy blackberries.

Why This Blackberry Frosting Works

🌰 Seed control built in - I hate crunching on blackberry seeds but love blackberries. That's exactly why I chop fresh berries fine or pulse freeze-dried ones into powder before they touch the butter, so the seed problem gets solved before it ever reaches a bite.

🧈 Simple four-ingredient base - No cornstarch, no cooked filling, no stovetop step, just butter, sugar, fruit, and cream, so there's nothing to cool down or wait on before you can frost.

🎨 Deep natural color without straining - I still remember the first batch that turned this deep, dramatic purple without a single drop of food coloring or a strainer in sight. Blackberries just bring more pigment than other berries, and this recipe lets that color do the work on its own.

Recipe Overview

Here's the fast version of how this comes together, no straining, no cooked puree, just real fruit beaten straight into the buttercream.

What You Need

Fresh Blackberries or Freeze-Dried: I go with whatever's actually in my kitchen or at farmer's market at the time. Summer means fresh blackberries from my own backyard bushes, and that's what I use. Freeze dried blackberries works just as well, sometimes better, since there's no extra liquid to deal with. Either one gets you real blackberry flavor, so don't stress over which to pick.

Butter, Sugar, Vanilla, Cream: I kept this short on purpose. Softened butter and powdered sugar are the base, and a splash of cream at the end loosens things up if I need it. And I love vanilla in my buttercream.

How to Make Blackberry Buttercream Frosting

Step 1: Chop or Powder the Blackberries

I always start here, before the butter's even out of the fridge. Fresh berries get chopped small with a knife, or I'll pulse them a few times in the food processor if I'm feeling lazy. Freeze-dried ones go straight into the processor until they turn into a fine powder. Getting this done first means one less thing to juggle once the buttercream's actually coming together.

Step 2: Beat the Butter Smooth

I beat the softened butter on its own for a minute or two until it's creamy with zero lumps. I know it's tempting to just dump everything in the bowl at once and save a step, but I've done that and ended up with a lumpy, uneven frosting I had to fix later. Better to get this part right upfront.

Step 3: Add the Powdered Sugar

I add the powdered sugar in stages, not all at once, unless I want to spend the next ten minutes wiping sugar off every surface in my kitchen. Mixing on low first keeps it contained, then I bump the speed up once it starts looking like real frosting.

Step 4: Mix in Vanilla and Blackberries

In goes the vanilla, then my chopped berries or blackberry powder. I mix just until the color turns even all the way through and stop there. I've overmixed at this stage before thinking more is better, and it just makes frosting texture off.

Step 5: Adjust With Cream

If the frosting feels too stiff to spread or pipe, I add cream a small splash at a time until it loosens up.

Equipment

• Food processor
• Stand mixer or hand mixer
• Mixing bowls
• Piping bag and tip (optional)
• offset spatula (optional, for sheet cakes)

Ingredients

Blackberries

• ½ cup chopped fresh blackberries or ½ cup freeze-dried blackberries pulsed into powder

Buttercream Base

• ¾ cup 12 tablespoons unsalted butter, softened
• 3 cups powdered sugar
• 1 teaspoon vanilla extract

For Consistency

• 1 to 2 tablespoons heavy cream as needed

Instructions

• Chop fresh blackberries fine with a knife, or pulse freeze-dried blackberries in a food processor until they turn into a fine powder. Do this before starting the buttercream so it's ready to go.
• Beat the softened butter on its own for a minute or two until it's smooth and creamy with no lumps.
• Add the powdered sugar in stages, mixing on low at first so it doesn't fly everywhere, then increasing speed once it starts looking like frosting.
• Mix in the vanilla extract, then add the chopped blackberries or blackberry powder. Mix just until the color turns even throughout, stopping as soon as it looks uniform.
• Add heavy cream a small splash at a time if the frosting feels too stiff, mixing until it loosens to a texture that holds its shape but spreads or pipes easily.

Notes

I chop or powder the blackberries before they touch the butter because skipping that step leaves gritty seed bits in every bite, and there's no fixing that once the frosting's already mixed.

Letting the finished frosting sit for 15 to 20 minutes before using deepens the purple color a bit more, since the fruit has extra time to blend fully into the butter and sugar. If I only have salted butter on hand, I use it as is and skip adding any extra salt to the recipe.

Enough to fill and cover one 2-layer 8 inch cake.

Fresh vs. Freeze-Dried: Which to Use

Honestly, it just depends on what season it is and what's sitting in my kitchen. Summer means fresh blackberries from my backyard bushes or a farmer's market trip, and that's what goes in. The rest of the year, when fresh ones look sad and cost way more than they should, I grab freeze-dried instead, and it works just as well since there's no extra liquid to fight with. Neither one is the "right" choice here, they're just suited to different times of year.

Tips for Texture and Color

Fixing Seedy or Gritty Frosting

If I bite into a gritty piece after mixing, it almost always means the berries didn't get chopped or powdered fine enough before going in. I just run them through the food processor a little longer next time, or push the powder through a fine sieve if I really want it silky.

Getting a Deeper Purple

I've noticed the color actually gets richer if I let the frosting sit for 15 to 20 minutes after mixing, no extra berries needed. The fruit just needs a little time to fully blend into the butter and sugar, and the purple deepens on its own.

Ways to Use This Frosting

I use this one everywhere. It pipes onto cupcakes, spreads between cake layers, and works great as a filling for macarons if I'm in the mood to get fancy. My favorite pairing is chocolate cake, that deep purple against dark chocolate looks incredible without any extra effort.

Storage Instructions

I keep leftover frosting in an airtight container in the fridge for up to a few days. Before using it again, I let it sit out at room temperature for 20 to 30 minutes, then give it a quick re-whip to bring the texture back to fluffy before piping or spreading.
