First you need to prepare your Oreo cookies. This is Peanut Butter icing is yummy and rich and sweet and we have found that it tastes best if you remove the Oreo filling before you crush up the cookies. Crush your Oreo cookies on the coarse side. You need the cookie crumbs to be small enough so you can use a decorating tip to frost your cupcakes but big enough that they are not just cookies crumbs. Finally, for the prettiest looking Peanut Butter Oreo Buttercream Frosting sift out the cookie dust with a strainer or a sieve.
Now you are ready to make your Peanut Butter Oreo Frositng. First, add peanut butter and softened butter to the mixer and mix them until they are combined. Then add the Powdered Sugar and mix, first on a low speed and then when the powdered sugar begins to be combined with the peanut butter/butter mixture increase the mixer speed to medium.
Add milk, one tablespoon at at time, until the peanut butter frosting is the right consistency.
Add the oreo pieces to the peanut butter frosting and then fold them into the frosting with a spoon instead of using the mixer.
Two Sisters Tip: This is not a “make-ahead” frosting. You need to frost your baked goods within a few hours of making this frosting. If you refrigerate the frosting and take it out to frost the next day, when you stir it up the cookie crumbs will blend into the frosting and turn the frosting into a brownish/grey color. However, it is fine to frost your cupcakes and then refrigerate the frosted cupcakes. It is the stirring after refrigerating that causes the problems.
How much frosting will you need? That always depends on how thick or thin you apply the frosting or how much decorating you do but here are a couple of guidelines. Our recipe should make enough Peanut Butter Oreo Buttercream Frosting to cover a 9″ x 13″ sheet cake or a two-layer 8″ cake. If you are making cupcakes, you should be able to frost 24 cupcakes if you apply the frosting with a knife. If you swirl on the frosting with a pastry bag you should be able to frost 15-18 cupcakes depending on the size of the swirl.
This Peanut Butter Oreo Buttercream Frosting is delicious and tastes great on any number of baked goods. It would also be great as a filling layer in a cake. If you love Peanut Butter and Chocolate, you’re gonna love this frosting!
