Cube the butter and set aside to soften.
Mix the ground almonds with caster sugar. Add the softened butter and mix until everything is well blended. I used a mix of almond flour and almond meal. I had about 60 gms of almond meal, so ground 40 gms of almonds to make it 100 gms.
Add vanilla essence along with milk.
Finally, add the flour and knead lightly until it comes together as a dough.
Cling wrap the dough and let it chill in the fridge for an hour.
Preheat the oven to 185C.
Roll out the dough to 1/8 inch thickness, using a flour cookie cutter, cut out cookies. I made the entire dough into a single log. You will have to flour the board each time you roll it out. I divided the log into two, with one half, I sliced it out plain.
Arrange on a baking sheet lined with parchment and bake until the cookies start to brown at the edges. Mine took about 12 mins to get done.
Allow to cool down completely.
Then spread with apricot jam on one cookie, Chocolate ganache on the other. Sandwich and enjoy!
