For the Blueberry Puree/Filling:

1 cup fresh or frozen blueberries
2 tablespoons granulated sugar
1 teaspoon lemon juice
Optional: 1 tablespoon blueberry jam for extra sweetness

For the Buttercream:

1 cup (2 sticks) unsalted butter, softened

1 teaspoon vanilla extract
1–2 tablespoons milk or cream (as needed for consistency)

Instructions

📝 Instructions:

Step 1: Make Blueberry Puree

In a small saucepan, combine blueberries, sugar, and lemon juice.
Cook over medium heat until berries release juice and soften (about 5–7 minutes).
Mash gently with a fork or use an immersion blender for a smooth puree.
Strain through a fine mesh sieve to remove skins if desired. Let cool completely.

Step 2: Prepare Buttercream

In a large bowl, beat softened butter with an electric mixer on medium speed until creamy (2–3 minutes).
Gradually add powdered sugar, one cup at a time, mixing on low until incorporated.
Add cooled blueberry puree or jam and vanilla extract; beat until smooth and fully combined.
Adjust consistency with milk or cream if needed. Frosting should be thick enough to pipe but soft enough to spread.

Step 3: Frost Cakes, Cupcakes, or Macarons

Apply a crumb coat if frosting a layered cake. Chill for 15–20 minutes.
Frost the cake or cupcakes smoothly or pipe decorative swirls.
Optional: top with fresh blueberries, edible glitter, or sprinkles for garnish.

Notes

Freeze-Dried Option: Grind freeze-dried blueberries into a powder and mix into buttercream for concentrated flavor without extra liquid.
Macaron Filling: Use a thicker puree or jam to avoid making macaron shells soggy.
Make Ahead: Frosting can be made a day ahead and stored in the fridge; bring to room temperature and re-whip before using.
