Step by Step Instructions

Step 1: Add the butter and the vanilla extract to a mixing bowl. The butter needs to be what we call, slightly softened which is somewhere between straight out of the refrigerator and room temperature. If the butter is too cold it will be hard to mix with the vanilla.  If it is too soft, it will start melting during the mixing process and your frosting consistency will be off. 
Step 2: Mix the butter and the vanilla together on medium speed until thoroughly combined (about 2 minutes.)  You really want the vanilla to meld with the butter to enhance the flavor of the frosting.
Step 3: Use a spatula to scrape the butter and vanilla mixture down from the sides of the bowl.

Step 4: We use a food scale to measure 1 Pound of Powdered Sugar.  If you don’t have a food scale, measure 4 cups instead. We normally do not sift the powdered sugar and instead rely on the mixer to do that work for us.
Step 5: Add the powdered sugar to the butter/vanilla mixture in the mixing bowl.
Step 6: Here is a Two Sisters Tip – cover the mixer with a towel during this part of the mixing process to keep the powdered sugar from flying out of the mixer.
Step 7: Start your mixer (or electric beater) on the lowest setting and keep it on low until the butter and sugar are incorporated (about 30 seconds). Stop the mixer and scrape down the sides of the bowl and then increase the speed to medium-high and mix for another 30-45 seconds so the frosting gets light and fluffy.

Steps 8-9: This is the fun part of the recipe where you get to taste your frosting. You are trying to determine if the consistency is correct or if it needs more milk or maybe a little more vanilla extract. If it tastes great, test the consistency.  Too thick? Add some milk and mix again to check to see if it is now the right consistency.  The amount of milk to use depends on the state of your frosting and sometimes the time of year (if it is a hot humid day, you might not need to add any milk.) A good rule of thumb is to add the milk a teaspoon at a time. You can check out our FAQ section below to see some other advice on making the perfect batch of frosting.

Step 10: Now we need to talk about Oreos.  Should you include the creamy centers in your frosting?  This is definitely a personal taste issue.  We remove the filling from the Oreo Cookies when we make this frosting.  Buttercream is already on the sweet side and adding the cookies with the creme filling made the Oreo frosting too sweet for us, personally.  But it might not be the same for you.  So let your palette be your guide and either remove the center of the cookies (or not.). Now that you’ve decided about the Oreo filling, you need to give the Oreo cookies a rough chop. The pieces need to be on the coarse side.  This is the trickiest part of making this frosting. 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 crumbs that will change the color of your frosting (more on that later.) This is the size of the Oreo pieces that we found worked best.  We also sifted the tiny crumbs out and didn’t use those.  We only used the small pieces of cookies.
Step 11: Add the Oreo cookie pieces to the bowl and use a spoon or a spatula (not the mixer) to fold them into the frosting.
Step 12: Your Oreo Buttercream is all done – so pretty and so yummy!

Step 13: Two Sisters Heads Up!  As we mentioned in the previous section, this is what happens to the frosting when one of two things will happen. 1) You use too fine of Oreo crumbs and you mix them into the frosting with the mixer instead of a spoon or spatula or 2) you refrigerate the frosting and go back and stir it after it has been refrigerated.  The cookie pieces blend right into the frosting, turning it almost gray.  It still tastes good but it DOES not look good.  In other words, this is not a “make the night before and frost the next morning” frosting.  

How to Serve

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 icing 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 and a decorating tip you should be able to frost 15-18 cupcakes depending on the size of the swirl.

Expert Tips and FAQ’s

Does the frosting need to be refrigerated?

No, the frosting does not need to be refrigerated. For example, brownies frosted with this Oreo Buttercream would be fine left out on the counter for 2-3 days if the pan was tightly covered with aluminum foil. That said, we usually refrigerate our frosted desserts to keep the baked good from going stale even if the frosting would be fine. We think frosting tastes best at room temperature so we will then remove the item from the refrigerator a couple of hours before we will serve them.

How do I store any leftover frosting?

Frosting stored in an air-tight container in the refrigerator should be good for up to a week. If you carefully wrap the frosting in order to avoid freezer burn, the frosting should be fine in the freezer for 3-4 mon

What should I do if my frosting is too sweet?

Buttercream is a sweet frosting and the addition of the Oreo Cookies also ups the sweetness level. One thing you can do if it seems too sweet for your palette is to add a pinch of salt to the frosting. But please note that a little salt goes a long way. We cannot stress enough that a pinch (10-15 granules of regular table salt) is all you usually need. Even 1/4 a teaspoon of salt would probably ruin the frosting. Add the salt and mix again and see if that has cut down on the sweetness level.

What should I do if my frosting turned out too thick?

Add another teaspoon of milk and mix again. Continue to add the milk, a teaspoon at a time, until the frosting is the consistency that you like it

What should I do if my frosting turned out too thin?

Temperature plays a big part in the consistency of frosting. A thin frosting could mean that the butter has gotten overworked and is too melted. The first thing to do is refrigerate the frosting for an hour and then check to see if the frosting has set back up again. If not, the next step is to add more powdered sugar or cornstarch. Start with either 1/2 cup of Powdered Sugar or 1 tablespoon of Cornstarch. Mix again and see if the consistency is better. Remember to do this BEFORE you add the Oreo Cookie pieces or you will have a batch of gray frosting (see the note above.)

Is there a substitute for the milk?

Yes. You can use Half n’ Half or Whipping Cream or even almond milk or another milk substitute.

Notes

Two Sisters Heads Up!  This Oreo Frosting can turn gray if you do one of two things: 1) You use too fine Oreo crumbs and mix them into the frosting with the mixer instead of gently folding them into the frosting with a spatula or spoon or 2) you refrigerate the frosting and go back and stir it after it has been refrigerated.  The cookie pieces blend right into the frosting, turning it almost gray.  It still tastes good but it DOES not look good.  In other words, this is not a "make the night before and frost the next morning" frosting.
