This raspberry buttercream frosting is made with 6 ingredients including blended fresh raspberries and tastes amazing on your favorite cakes, cupcakes and cookies.
Put the raspberries and sugar in the container of a high-power blender and blend until smooth (I suggest using a small blending container or blender – a large one will not work). (makes ¼ cup raspberry puree)
In the bowl of a standing mixer fitted with the paddle attachment, or in a large bowl with a handheld mixer, beat together the butter.
Then add the raspberry puree, vanilla, sea salt and 1 cup powdered sugar until smooth.
Add remaining powdered sugar, 1 cup at a time, until you reach your desired consistency.
Use to frost your favorite cakes, cookies, etc.

Notes
Ingredient Notes & Substitutions
Raspberries. Fresh raspberries are the best choice. However, you can use frozen raspberries - just let them thaw in a colander to drain out excess water before blending.
Granulated sugar. Sometimes raspberries can be a little tart, so we blend them with a Tablespoon of granulated sugar to bring out their sweetness. You can use honey or brown sugar, or omit the sugar if your raspberries are very sweet.
Salted butter. unsalted butter works well too.
Vanilla extract. the seeds of 1 vanilla bean or vanilla bean paste are good substitutes.
Fine sea salt: just a pinch of salt really brings out the flavor.
Store/FreezeStore leftover raspberry buttercream frosting in an airtight container in the refrigerator for up to 5 days or freezer for up to 1 month. I often freeze it in the piping bag, just be sure to remove the metal tip.Let the frosting come to room temperature before using. Make sure to be patient and do not microwave the frosting.
