Strawberry Rice Krispie Treats

FOR THE BUTTERCREAM

1. In the bowl of a stand mixer fitted with the paddle attachment, or in a large bowl with an electric mixer, beat butter on medium-high speed for about 5 minutes.
2. With the mixer on low speed, slowly add in powdered sugar, and continue beating until well blended.
3. Add in vanilla, and 1 teaspoon of milk. Mix on low speed until incorporated.
4. Beat at high speed until frosting is smooth and fluffy; about 4-5 more minutes. If your frosting is too thick, gradually add a little more milk, 1 teaspoon at a time until you reach the desired consistency.
5. Spread or pipe frosting onto cooled marshmallow cereal treats and top with fresh strawberries.
