Line a 20x20cm (8×8 inches) dish with parchment paper and lightly grease with cooking spray. Roughly chop the almonds. Spread out the chopped almonds over the prepared dish. Set it aside.
Step 2
Add the butter and sweetener to a small pan. Heat up on low heat until the butter has melted and the sugar has dissolved. Bring to a gentle simmer, stirring every 30 seconds. Add your candy thermometer into the center of the mixture and continue to cook over low heat until the thermometer reaches 150°C (300°F).
Step 3
Remove from the heat. Stir continuously to ensure the butter and sweetener don’t separate. Pour the mixture over the chopped almonds.
Step 4
Let the mixture sit for 2-3 minutes. Top with chocolate chips and cover with a piece of aluminum foil. Let it sit for another 5 minutes. After 5 minutes, remove the foil and gently spread out the chocolate layer using a rubber spatula.
Step 5
Refrigerate until firm. When done, break into pieces and serve immediately. Optionally, sprinkle with some more chopped nuts or coarse salt. Enjoy!
