Line a small baking sheet with parchment. *don't skip this or it sticks* Set aside.
Mix all ingredients (except the chopped almonds) in a food processor, mixer, or whisk by hand.
Taste and adjust to your preference (more stevia/cacao/salt/almond extract)
Pulse or stir in your choice of almonds (slices, slivers, whole or chopped)
Spread the chocolate on the parchment-lined baking sheet with a spatula.
Sprinkle a few almonds on top, if you like.
Freeze for about 30 minutes, until firm.
Chop or break into pieces. Enjoy!
Notes
I made this recipe in my food processor starting with 1 heaping cup dry roasted almonds that I processed into butter. Scrape down the sides and add in the rest. It's cheaper that way
