In a large bowl, whisk together the dry ingredients. Cut in the butter and peanut butter and work mixture until it looks like a coarse meal.

Stir in syrup and milk.

Shape into a long log shape 2" wide on plastic wrap. Seal and refrigerate to chill for 1 hour. The mixture is dry but it will hold together.

Remove from refrigerator and slice about 1/4" thick and place on an ungreased cookie sheet.

Spread about 1/2 tsp. of peanut butter in the center of one of the cookies and cover with another slice.

With the tines of a fork seal around the edges.

Bake at 350F. for 12 min.

Cool on the cookie sheet for 5 min. then remove to a cooling rack.
