Shortcakes (from diabetic cook book)

I've been trying some recipes from a diabetic cook book - just to be healthier and I've found a few good ones.  This was an excellent dessert! 
(They want you to drain the yogurt through a sieve for 30 minutes, I didn't, the sauce is just a little runny, but not bad.)
2 c flour
1 tsp baking powder
1/2 tsp baking soda
3 1/2 Tb sugar
 Cut in 1/2 cub butter until mixture is crumbly.
Add 2 tsp vanilla
1 cup yogurt (any flavor to match your fruit)
Mix until dry ingredients are wet.  Knead on a floured surface 8X.
Roll 1/2 inch thick & cut into circles 2 1/2 -3 " ( I used a wide mouth jar lid)
Bake 425 for 12 minutes.

Fruit:
4 cups fruit (I used peaches and strawberries)
2 tsp sugar

Topping: 
2 cups yogurt
2 Tb sugar
3 Tb jam (not sure you really need this)

Cut biscut in half, bottom layer, fruit, topping, top of biscuit.
