First, gather up and measure out all of the strawberry frosting ingredients.
Next, thinly slice and dice the fresh strawberries. You will need 1 ½ cups of the sliced strawberries.
Then, transfer the strawberries to a blender and blend until a thin puree is reached.If needed, use a silicone spatula to scrape the sides down in between blending to make sure there are no strawberry chunks left.
Next, transfer the room temp butter to a large mixing bowl set in a KitchenAid stand mixer prepared with a whisk attachment and beat the butter until it’s smooth and creamy.
Add in the powdered sugar and vanilla extract and beat again until completely mixed.
Then, slowly add the strawberry puree, starting with a ½ cup, mixing again between each addition. Don’t add too much of the puree at one time.Once all ingredients are combined, increase the mixer to high speed and whip for 8–10 minutes. This step ensures the frosting is fluffy and forms stiff peaks on the tip of the whisk.-You don’t want this frosting to turn out too thin or soupy so only add the pureed strawberries gradually and as needed. You may not use all of the puree.-If your frosting mixture looks like it may be too thin for piping, mix in a little more powdered sugar until you get the right consistency.
This strawberry frosting is ready when stiff peaks form on the tip of the whisk.
Finally, transfer the strawberry frosting to a pastry piping bag and close off with a piping bag tie. You can use any leftover whole strawberries or strawberry slices to decorate the cupcakes or cake.
