Blueberry Frosting

Blueberry frosting made with real blueberry puree and light mascarpone whipped cream, perfect for filling cakes and decorating cupcakes.

This blueberry frosting is my favorite way to add blueberry flavor to cakes and cupcakes.

It starts with a thick blueberry puree mixed into mascarpone whipped cream for a light, fluffy frosting.

As a French baker, I love how smooth and pipeable it stays, with a natural purple color that works with lemon, vanilla, or chocolate cakes.

Why you'll love this recipe

• Real blueberry flavor – Made with blueberry puree (fresh or frozen berries), not extract.
• Light but stable texture – A blueberry whipped cream mascarpone frosting that pipes clean swirls and holds on cakes.
• Perfect for many desserts – Use this blueberry frosting for cupcakes, layer cakes, berry parfaits, and more.

Ingredients you need

You need these ingredients to make this blueberry frosting (mascarpone whipped cream frosting):

• Mascarpone cheese – Use full-fat cold mascarpone.
• Heavy cream – Cold heavy whipping cream, 30–35% fat.
• Powdered sugar – Confectioners’ sugar for a smooth blueberry icing.
• Vanilla – Pure vanilla extract or vanilla bean seeds.
• Blueberries – A homemade blueberry compote made from fresh or frozen blueberries; avoid runny blueberry sauce so the frosting stays firm.

Tips for this recipe

• Fresh or frozen blueberries – Both work for the blueberry puree. If using jam, reduce added sugar so the frosting stays thick.
• Cold ingredients only – Chill the bowl and tools for 10 minutes to help the mascarpone whipped cream get firm.
• Don’t over-whip – Mix slowly with an electric mixer. Over-whipping breaks the cream and makes the frosting grainy.
• Check the texture – Stop mixing as soon as it looks smooth, fluffy, and pipeable.
• Chill before using – Refrigerate the frosting after filling or decorating the cake so it sets and holds its shape.

How to make blueberry frosting

Cook the blueberries with sugar, lemon juice, and zest over low heat for 10–15 minutes until thick.

Blend with a hand blender to get a smooth mixture.

Strain through a fine sieve to make a thick, seed-free blueberry puree, then chill completely in the fridge.

Place the cold mascarpone, cold heavy cream, powdered sugar, vanilla, and chilled blueberry puree in a large bowl.

Whip on medium-low speed for 2–3 minutes until the frosting turns smooth, fluffy, and firm.

Use immediately to fill or frost cakes and cupcakes, or refrigerate to let it set.

Serving Suggestions

• Blueberry cupcakes with a generous swirl of frosting
• Lemon or vanilla layer cakes as a fruity cake filling
• Chocolate cakes for a sweet-tart contrast
• Pancakes or waffles topped with blueberry whipped cream
• Berry parfaits layered with granola and fresh blueberries
• Fruit tarts filled with mascarpone blueberry frosting
• Mini bundt cakes or loaf cakes for a simple blueberry topping

Storage

• Fridge: Store the frosting in an airtight container in the fridge for 2–3 days.
• Freeze: It can freeze only once used as a cake filling, not on its own, as whipped cream mascarpone frosting cannot be re-whipped.

Recipe Variations

• Blueberry cream cheese frosting - Mix blueberry puree into a classic cream cheese frosting for a tangier taste.
• Blueberry buttercream - Add the puree to Swiss meringue buttercream or vanilla buttercream for a firmer, room-temperature stable frosting.
• Lemon blueberry frosting - Combine lemon mascarpone frosting with blueberry puree for a bright flavor.
• Extra sturdy version - Use my mascarpone frosting for cake and fold in blueberry puree for a thicker, pipeable texture.

Recipe Questions

Can I use frozen blueberries?

Yes, thaw and drain them if they release a lot of liquid.

Can I use blueberry jam?

Yes, but reduce the added sugar because jam is sweeter than puree.

Can I add food coloring?

A drop of blue or purple gel helps intensify the natural color.

Can I use freeze-dried blueberry powder?

Yes, it gives a stronger flavor without extra moisture.
