Whole grain tea-biscuits filled with fig jam

I remade the classic tea-biscuit recipe because I was curious if it could me made with whole grain flour and xylitol. Not very surprisingly, it can :) It's true tough that it's not that easy to handle it, I had to make the pieces by hand, that's why they don't look as pretty as they should. But despite all that, it's still very delicious :) You have to let them rest at least one night because that's when they gather the humidity from the jam and they become super soft. 

Ingredients:

• 16 dkgs of butter
• 15 dkgs of xylitol (powdered) 
• 6 egg yolks
• 25 dkgs of whole grain flour
• zest of one lemon
• 1 teaspoon of vanilla extract or flavour
• half a jar of fig jam
•  5 dkg of dark chocolate

Mix the soft butter with the sugar until it becomes fluffy. The easiest way is to use a mixer. When that's done, add the yolks one after the other. After that add the flour too and give it a good stir so that there aren't any lumps of flour in it. Add the lemon zest and the vanilla flavour too, and give it a last stir. You have two options from here: form little balls of it by hand or use a plastic bag, cut off the edge and push the dough out. Press them onto the baking tin. Bake them in the oven at 180 deg Celsius for 10 minutes tops until the edge becomes golden. Then wait until they cool down and stick the tops and halfs together with the jam. You can cover the top with melted dark chocolate.
