3/4 cup butter, softened
8 oz cream cheese, softened
1 egg yolk
1 c sugar
2 c flour
1 tsp vanilla
1/2 tsp salt
1 cup crushed Oreos
3/4 c chocolate chips
Heat oven to 350°.
Cream butter, cream cheese, and sugar together. Mix in egg yolk and vanilla.
Add flour and salt, a little at a time, until thoroughly mixed. Fold in Oreos and chocolate chips.
Bake 11-14 minutes, until bottoms are slightly browned.
I'd recommend baking these up after a night of chilling the dough in the fridge. The Oreos soften overnight and are easier to work with that way...but if you can't wait, they're still excellent immediately!
