Ingredient Checklist

• 12 small to medium fresh blackberries
• ½ cup (113g) unsalted butter, softened to room temperature
• 3 Tablespoons (23g) powdered sugar

Mash, Strain, and Mix

1. Soften the unsalted butter to room temperature.
2. Place the blackberries in a medium bowl.
3. Crush the blackberries with a fork or potato masher until they break down and release their juice.
4. Strain the crushed berries through a fine-mesh sieve, pressing gently to collect about 1/4 cup clear blackberry juice; discard or reserve the seeds and pulp.
5. Add the softened butter and powdered sugar to the strained blackberry juice.

6. Whip the mixture with a handheld mixer (or stand mixer with the paddle) until silky, smooth, and fluffy.

   

7. Taste and, if desired, stir in about 1/4 teaspoon salt and beat again.
8. If you want texture, fold in 1–2 tablespoons of the reserved berry pulp.

Tips for Silky, Spreadable Butter

• Make sure your butter is softened to room temperature so it whips up light and fluffy without lumps — the same softened-butter creaming step you’d use for a sour cream pound cake.
• Crush the berries really well to get as much juice out as possible before straining; I like using a potato masher plus a fork for this step.
• Press gently through a fine-mesh sieve — you should get about a quarter cup of blackberry juice for the best flavor.
• Powdered sugar blends in smoothly (as in a no-bake strawberry cheesecake), way better than granulated sugar, which can give you a grainy texture if not beaten long enough.
• If you’re using nondairy butter, expect it to look a little separated at first, but keep beating and it’ll come together.
• After mixing, give it a taste. If you used unsalted butter and want a hint of saltiness, stir in about ¼ teaspoon salt and beat it again.
• Move quickly when working with fresh juice and keep your finished blackberry butter chilled to keep it fresh longer.

Flavor Swaps and Add-Ins

• Try other berries: swap blackberries for raspberries, strawberries, blueberries — the lemon–blueberry combo, as in this Lemon Blueberry Fluff, is especially bright — or even a mix of your favorites; strain them the same way to keep it smooth.
• Add a citrus kick: stir in ½ to 1 teaspoon of lemon or orange zest for a fresh zing (for a feel of how zest can light up a recipe, these zesty lemon frosted cookies are a great example).
• Swap sweeteners: replace some or all of the powdered sugar with 1-2 teaspoons of honey or maple syrup for a natural sweetness shift (remember powdered sugar keeps the texture smoother).
• Spice it up: add a pinch of cinnamon or 1 teaspoon vanilla extract; for grown-ups, a splash of berry liqueur or bourbon is a lovely boozy touch.
• For some texture: save 1-2 tablespoons of the strained berry pulp and fold it back in for a chunkier, fruitier butter.
• Salt lovers: use salted butter or sprinkle up to ¼ teaspoon flaky sea salt on top for that delicious salty-sweet combo.

Fridge and Freezer Storage

Keep your blackberry butter fresh by storing it in an airtight container in the fridge for up to 2 weeks. For longer life, freeze it (up to 6 months). Rolling it into a log with plastic wrap or parchment makes portioning and serving nice and easy.

• In the fridge: store chilled and use within 2 weeks. Don’t leave it out too long because fresh berry juice can spoil faster than plain butter.
• In the freezer: freeze as a log or in portioned containers. Thaw overnight in the refrigerator, then slice off coins to melt over warm bakes like Brown Sugar Peach Cake.
• If you notice separation after thawing (this happens more with nondairy butter), just let it warm up a bit and beat again to bring it back together.

Answers to Common Questions

Yes, you can definitely make this blackberry butter using nondairy butter! Though I haven’t tried it myself, it should work just as well. Because nondairy options rely on oils, you might see some separation during mixing, so just keep beating and it will come together beautifully in the end.
