Sweet and slightly tart raspberry jam gets mixed with fluffy buttercream frosting for the perfect spring and summer frosting. This raspberry buttercream recipe makes enough to top 24 cupcakes or a 9-inch layer cake.
In the bowl of a stand mixer fitted with the paddle attachment, beat the butter on medium-high speed for about 5 minutes.
Turn the mixer down to low speed and gradually add in the confectioners' sugar until it is completely incorporated. Add in vanilla and 3 tablespoons of the raspberry jam; mix until incorporated. Turn off the mixer and check the buttercream for taste and texture and scrape down the sides of the bowl. Gradually add in the last 2 tablespoons of raspberry jam until you reach the desired level of raspberry flavor. (Please note that adding more than the recommended 5 tablespoons could result in a thinner frosting.) Turn the mixer back up to medium-high speed and beat the mixture for about 3-4 minutes or until light and fluffy.
Spread or pipe onto cake or cupcakes.
Notes
You can easily adjust the consistency of this recipe by simply adding in more milk a splash at a time.
If you are a fan of shortening in your buttercream, simply omit one stick (1/2 cup) of butter and replace with 1/2 cup shortening.
Covered and refrigerated frosting can be stored for up to three days. Simply bring it to room temperature and beat with an electric mixer until smooth. You may need to add a couple of teaspoons of heavy cream or milk to revive the consistency. Frosting can also be frozen for up to a month.
If you garnish with sprinkles, make sure you do this immediately after you frost your baked goods. Once the top layer of the buttercream crusts, nothing will stick.
