Heat oven to 350 degrees F.

Combine your dry ingredients in a medium size bowl.

In a separate bowl, combine your yogurt and butter with a mixer. Mix well, though it may have a bit of a lumpy appearance (that is okay). Add in your sugars, mixing until well combined, followed with your eggs and vanilla. Mix until all items are well combined.

Add your dry ingredients to your wet ingredients and stir until combined, but do not over mix. Add in your chips or mix-ins. The dough will be very sticky.

Drop by spoonfuls onto a cookie sheet, leaving approximately 1" between cookies.

Bake for 9-11 minutes. They will still be soft when they come out.

Immediately after removing from the oven, separate from the cookie sheet with a spatula so that they do not stick. Either leave on the sheet to cool or transfer to a wire rack. Makes approximately 3 dozen 2" cookies.
