Ingredients for Blueberry Frosting
- 1 cup (140 g) fresh or frozen blueberries (thawed if frozen)
- 1 Tablespoon granulated sugar
- 1 Tablespoon lemon juice (freshly squeezed for best flavor)
- ⅛ teaspoon salt
- 1 cup (226 g) unsalted butter, softened (to room temperature)
- 3 ½ cups (438 g) powdered sugar (sifted for smoother frosting)
Step-by-Step Instructions
- Prepare the blueberry sauce: In a small or medium-sized saucepan, combine blueberries, granulated sugar, lemon juice, and salt. Stir well to mix.
- Cook the berries: Place the saucepan over medium-low heat. Stir frequently until the berries soften and release their juices. Use a spatula or potato masher to smash the berries as they soften.
- Simmer and thicken: Bring the mixture to a gentle simmer (avoid a full rolling boil). Cook until the sauce thickens and the spoon leaves trails in the mixture. This should take about 5-7 minutes.
- Strain the sauce: Pour the mixture through a fine mesh strainer into a heatproof container. Press the sauce through the strainer to extract as much liquid as possible. Discard the leftover solids. You should have about ¼ cup (65g) of sauce.
- Cool the sauce: Allow the blueberry sauce to cool completely before using it in the frosting. This ensures the frosting doesn’t break.
- Beat the butter: In a large mixing bowl, use an electric mixer to beat the softened butter until it’s light and smooth.
- Add powdered sugar: Gradually add the powdered sugar to the butter, mixing until fully combined and smooth.
- Incorporate the blueberry sauce: Add the cooled blueberry sauce 1 Tablespoon at a time, mixing well after each addition. Stop after 4 Tablespoons (66g) and check the consistency. If the frosting is too thin, avoid adding more sauce.
- Use or store: Your Blueberry Frosting is ready to use! Spread or pipe it onto cakes, cupcakes, or cookies. Store any leftovers in an airtight container in the refrigerator for up to 3 days.
Perfect Pairings: What to Frost with Blueberry Frosting
This vibrant blueberry frosting is a versatile topping that pairs beautifully with a variety of baked goods. Try it on vanilla cupcakes for a classic combo, or spread it over lemon cake for a tangy-sweet treat. It also works wonders on cinnamon rolls or as a filling for layer cakes. For a fun twist, use it to frost sugar cookies or drizzle it over pancakes for a breakfast upgrade!
Storage Tips: Keeping Your Frosting Fresh
Store your blueberry frosting in an airtight container in the refrigerator for up to 5 days. If it hardens, let it sit at room temperature for 15-20 minutes, then give it a quick whip with a hand mixer to restore its creamy texture. For longer storage, freeze it in a freezer-safe container for up to 2 months—just thaw and re-whip before using.
Time-Saving Hacks for Busy Bakers
If you’re short on time, use store-bought blueberry jam instead of making the sauce from scratch. Just reduce the amount to 4 tablespoons and skip the straining step. Alternatively, prepare the blueberry sauce ahead of time and store it in the fridge for up to 3 days, so it’s ready to go when you need it.
Equipment Essentials: Tools You’ll Need
To make this recipe a breeze, grab a fine mesh strainer for smoothing the blueberry sauce and an electric mixer for whipping the butter and sugar to perfection. A potato masher or sturdy spatula will help smash the berries, and a heatproof container is ideal for cooling the sauce before mixing it into the frosting.
Common Questions: Troubleshooting Your Frosting
Worried about your frosting breaking? Make sure your blueberry sauce is completely cooled before adding it to the butter and sugar mixture. If the frosting becomes too thin, add a bit more powdered sugar to thicken it. On the flip side, if it’s too thick, a splash of milk or cream can help loosen it up. Remember, gradual additions are key to achieving the perfect consistency!
Blueberry Frosting
Ingredients
- 1 cup fresh or frozen blueberries
- 1 Tablespoon granulated sugar
- 1 Tablespoon lemon juice
- ⅛ teaspoon salt
- 1 cup unsalted butter softened
- 3 ½ cups powdered sugar
Instructions
- Combine blueberries, sugar, lemon juice and salt in a small or medium-sized saucepan and stir well.
- Place on stovetop over medium-low heat and stir frequently until the berries are softened and release their juices. Smash the berries with your spatula (or with a potato masher) as they soften.
- Bring mixture to a gentle simmer or slow bubble (don’t bring to a full rolling boil, reduce the stovetop heat if needed) and cook until the mixture is thickened and the spoon leaves trails in the sauce.
- Pour through a fine mesh strainer into a heatproof container. Squeeze as much of the sauce through the strainer as possible and discard the remnants. You should have approximately ¼ cup (65g) of sauce (if you have less that’s fine, but if you have more it may not be reduced enough).
- Allow to cool completely before proceeding with the recipe.
- Place butter in a large mixing bowl and use an electric mixer to beat until light and smooth.
- Gradually add powdered sugar to the butter, stirring until completely combined.
- Add the cooled blueberry sauce by stirring in 1 Tablespoon at a time until completely combined. You should only have about 4 Tablespoons (66g) of sauce or less, if you have more than this your sauce may be thinner so check the consistency at 4 Tablespoons before proceeding. Adding too much sauce could cause the frosting to break.
