Preheat over to 375ºC. Line a baking sheet with parchment paper.
Combine dry ingredients in a large bowl.
Add butter, and cut with two knives, or pastry cutter until butter pieces are no larger than popcorn kernels.
Add kefir vanilla; incorporate into the dough with a spoon until no dry spots remain.
Using a cookie scoop or two spoons, drop pieces of dough onto the cookie sheet (I got 12).
Bake for 15-20 minutes, or until a toothpick comes out clean.
Cool on a wire rack before serving.
Top with freshly whipped cream and chopped strawberries.
