Oreo Buttercream Frosting

So I had a student bring cupcakes with this frosting on the other day, they were amazing, not sure where the frosting recipe is from, but I definitely don't want to loose it.

3/4 C. butter
1/2 C. shortening
4 cups powdered sugar
2 tsp. vanilla
2 tbsp. milk
1/4 tsp salt
6 crushed oreos, crush well before using your mixer.

Blend together and enjoy! Top with oreos, it will make a pretty thick frosting, but it is awesome!

Awesome Play Dough Recipe by Shannon Oler

Here's my playdough recipe:
1 cup flour
1/2 cup salt
2 tsp. cream of tartar
1 cup water
...2 Tbsp. oil
1 tsp. food coloring

Combine flour, salt and cream of tartar in a large saucepan. Gradually stir in 1 cup water mixed with oil and food coloring. Cook over medium to high heat, stirring constantly until a ball forms. Remove from heat, cool and knead until smooth on wax paper. Store in airtight container.
It's a really weird consistency until the chemical reaction happens to form the playdough so it may seem like it's not working, but just keep stirring. Have fun!

So I keep loosing this recipe, because it is saved on Facebook, so I thought I would post it here. Enjoy!
