Oreo Frosting Pro Tips

You will definitely need a mixer for this frosting! It takes about 8-12 minutes to whip the butter, to set the frosting up for the correct consistency, when you add the sweetened condensed milk and crushed Oreos and that's easy!
Make sure your butter is at softened at room temperature. You want it softened so it can properly incorporate the condensed milk.
Add the sweetened condensed milk slowly, in 3 or 4 batches, mixing in-between in addition.

If you don't beat the butter until it becomes pale white, the frosting will not thicken up, which would probably be ok on these brownies, but if you wanted to use on cupcakes, you wouldn't be able to pipe it and it also helpsto chill the frosting in the fridge 10-20 minutes before piping the frosting as you would cream cheese frosting.

Storing Oreo Frosted Brownies

Once you've frosted the oreo brownies you will need to store them in the fridge in an airtight container.
Bring to room temperature when you're ready to serve them or eat them straight from the fridge! So good either way!
