Preheat the oven to 350 degrees F. In a medium bowl, cream the butter/oil and natural sweetener together.
Add in the eggs, stir until well combined.
Finally mix in the cocoa powder, salt and extracts. Form 2 inch balls. Place on a cookie sheet about 2 inches apart. Flatten the balls. Bake for 10 minutes. Allow to cool on the cookie sheet before removing.
Meanwhile make the white chocolate filling.
Place cocoa butter in a double boiler and heat on medium high until fully melted (or a microwave safe bowl and heat on high for one minute, check and heat for 30 seconds until melted). Melting cocoa butter takes longer than traditional fats.
Stir in natural sweetener.
Stir in extracts and salt.
Allow the white chocolate to cool a little (if it is too hot, it separates). Once a spreading consistency, use a knife to spread enough on the bottom of each cookie to cover it completely and allow to cool by placing the cookies with the melted chocolate side up on the counter or baking sheet. Allow to cool and enjoy! If you choose to put in the freezer for 2 minutes, they will set up faster.
