Ingredients

To make this Blackberry Frosting Recipe, gather the following ingredients:

1 cup (225 g) unsalted butter, softened to room temperature
3½ cups (420 g) powdered sugar, sifted for smooth texture
½ cup (75 g) fresh blackberries (or frozen, thawed and drained)
1–2 tablespoons (15–30 ml) heavy cream or whole milk
1 teaspoon (5 ml) pure vanilla extract
1/8 teaspoon fine sea salt

Fresh blackberries provide natural sweetness and color. Softened butter ensures a creamy base, while powdered sugar builds structure. Heavy cream helps adjust consistency, and vanilla enhances the berry flavor without overpowering it. Salt sharpens the sweetness and rounds out the taste.

Pro Tips for Perfect Texture and Flavor

First, reduce the blackberry puree before adding it to the frosting. Simmer blended berries for 5–7 minutes until slightly thickened. This step removes excess moisture and intensifies flavor, preventing runny frosting.

Second, beat the butter thoroughly before adding sugar. Whip it for at least 3–4 minutes until pale and fluffy. Proper aeration creates a light, smooth texture and eliminates dense, greasy frosting.

Third, add the blackberry reduction gradually. Start with one tablespoon and increase slowly. This method lets you control color and flavor while keeping the buttercream stable. If the frosting softens too much, chill it for 10–15 minutes, then re-whip.

These simple techniques elevate your blackberry buttercream frosting from good to exceptional.

Instructions

Step 1: Prepare the Blackberry Puree

Place blackberries in a blender or food processor. Blend until smooth. Pour the mixture into a small saucepan and simmer over medium heat for 5–7 minutes, stirring often. The puree should slightly thicken and reduce. Strain through a fine mesh sieve to remove seeds. Let it cool completely.

Step 2: Beat the Butter

Add softened butter to a large mixing bowl. Beat with a hand or stand mixer on medium-high speed for 3–4 minutes. The butter should look pale and fluffy. Scrape down the sides of the bowl to ensure even mixing.

Step 3: Add Powdered Sugar

Add powdered sugar one cup at a time, mixing on low speed first to avoid splatter. Increase to medium speed after each addition. Beat until fully incorporated and smooth.

Step 4: Incorporate Blackberry Reduction

Add 1–2 tablespoons of cooled blackberry reduction. Mix on medium speed until fully blended. Check the color and flavor. Add more reduction if desired, but do so gradually to maintain thickness.

Step 5: Adjust Consistency

Pour in vanilla extract and salt. Add heavy cream one tablespoon at a time until the frosting reaches your preferred consistency. Beat on high speed for 1–2 minutes for a light, airy finish.

Step 6: Frost and Decorate

Use immediately to frost cakes or cupcakes. For piping designs, chill briefly if needed. This Blackberry Frosting Recipe spreads smoothly and creates beautiful swirls.

Variations

For a cream cheese version, replace half the butter with 4 oz (115 g) softened cream cheese. This creates a tangy blackberry cream cheese frosting that pairs beautifully with carrot cake or red velvet.

To make a dairy-free option, use plant-based butter and coconut cream instead of heavy cream. The flavor remains rich and smooth.

For an intense berry punch, fold in a tablespoon of freeze-dried blackberry powder. This trick boosts color and flavor without adding moisture. You can also mix in lemon zest for a bright blackberry lemon frosting twist.

Each variation keeps the essence of this Blackberry Frosting Recipe while offering new flavor dimensions.

Storage and Serving Suggestions

Store leftover frosting in an airtight container in the refrigerator for up to 5 days. Before using, let it sit at room temperature for 20–30 minutes. Re-whip briefly to restore its fluffy texture.

You can freeze this frosting for up to 2 months. Thaw overnight in the refrigerator, then beat until smooth.

Serve it over vanilla bean cupcakes, chocolate layer cake, or lemon sheet cake. It also tastes amazing sandwiched between sugar cookies. The vibrant color makes it ideal for birthdays, bridal showers, or spring gatherings.

This Blackberry Frosting Recipe holds its shape well for piping roses, borders, or decorative swirls.
