In a large mixer bowl beat butter until whipped.
Then add in powdered sugar and vanilla and mix on medium until it blends together.
Add in flour and heavy cream and mix on medium-high until it's all combined.
It takes a little bit of time to come together, but as soon as it does, stop mixing.
I place a towel over the top so nothing flies out as I mix.
Use a small 1 tablespoon scoop to portion out the cookie dough.
Roll the cookies into smooth balls.
Place on a parchment lined baking sheet.
Place in fridge until they are cold about 30 minutes
*(If you don't refrigerate the cookie dough they will flatten slightly when baked and not stay in a ball shape)
Make sure you preheat your oven well at 325° I use an additional thermometer to be sure my oven is holding the correct temp while baking.
Bake at 325° for 15-17 minutes.
If you're rolling in powdered sugar, do it while the cookies are warm so the powdered sugar sticks, roll them twice to coat them well.
If you're adding glaze be sure they are completely cooled.
