To make the blueberry mixture for this creamy icing, all you need is fresh blueberries and a lemon!
To complete this delicious frosting recipe, you need just a few more ingredients - powdered sugar, unsalted butter, vanilla extract,salt, and the cooked blueberry mixture.
- Other fresh berries. I have not personally tested this recipe with a different variety of berry, but I do believe fresh raspberries would work great for this frosting.
- Dairy free butter. If you eat a plant based diet, or simply cannot eat dairy, there are a number of dairy free options to enjoy with this blueberry frosting. This one is my favorite.
How to Make Blueberry Frosting
- Cook the blueberries. Begin this frosting by placing the blueberries and lemon juice and zest in a small saucepan over medium heat. Cook, stirring occasionally, until the blueberries burst and syrup has formed. This takes about 10 minutes.
- Cool the blueberry mixture. Remove the blueberry mixture from the stove, and allow it to cool completely, about 10-15 minutes.
- Mix together the butter and blueberry mixture. Place the room temperature butter in the bowl of a stand mixer, and add the cooled blueberry mixture.
- Whip the butter and blueberry mixture together. Add the whisk attachment, and whip the blueberry mixture and butter on high, until it is well combined.
- Add the remaining ingredients. Once the blueberries and butter have been well mixed, add the powdered sugar, vanilla extract, and salt. Whip on high for 10-12 minutes, or until light and fluffy. Switch the paddle attachment, and whip for an additional 5 minutes to eliminate large air bubbles.
Prep Ahead Options
- Cook the blueberries ahead of time. If you are short on time, the blueberry mixture for this blueberry frosting can be made up to one week ahead of time. Simply follow the first step in the recipe, and once the blueberries are cooked and cooled, place them in an airtight container in the refrigerator for up to one week.
- Prep the entire recipe ahead of time. This recipe can be made ahead of time, and stored in an airtight container in the refrigerator for up to two weeks. Simply remove it from the refrigerator 2-3 hours before use. Before using the blueberry frosting, you will need to "rewhip" it on the mixer, using the whisk. Whip for about 5-10 minutes, and then switch to the paddle attachment and whip for an additional 5 minutes.
The really cool thing about most frosting recipes is that they can be frozen! If you decide to freeze, place in a large zip top bag, and lay flat to remove all the air bubbles from the bag. Freeze laying flat, and then remove from the freezer and place in the refrigerator about 24 hours before use. Then, follow the final part of step 3 in the instructions.
I have not tested this recipe with a different type of berry, but I think most berries would work well in this recipe.
Plant based or dairy free butter options should work in this recipe. I have not personally tested this (yet!), but use the same amount as the original recipe. Since most plant based butter options have a bit of salt in them, I would omit the salt from the blueberry frosting recipe. This is my favorite plant based butter. Brown Butter Cream Cheese Frosting
Tips and Tricks for Success
- Ensure the butter is very room temperature. This helps all the ingredients come together smoothly.
- Completely cool the blueberry mixture. If the mixture is a little warm, it will cause the butter to melt, and then separate, resulting in a grainy frosting.
- Do not overcook the blueberry mixture. Keep a close eye on the blueberries when they are cooking. Ensure there is a nice syrup forming and that the bottom of the pot is not beginning to dry out. This will provide you with the optimal blueberry flavor in your frosting.
