Preheat the oven to 160℃ (320℉) fan.
Melt the butter, cane sugar, and syrup in a small pot on medium heat.
Stir until the sugar dissolves (about 5 minutes).
Take the sugar mixture off the heat and stir in the flour, vanilla paste, and salt.
Add the almonds until they are all incorporated into the caramel.
Measure out 12-gram pieces of dough.
Roll them into balls.
Spread the balls out on a large lined sheet pan (I had 12 on one). You will need to bake them in batches.
Bake for about 10-12 minutes until golden brown.
Immediately after they come out of the oven, flatten the tops of the cookies with a spatula or the bottom of a glass.
Turn the glass over and swirl the cookies in circles to round them. You will need to act fast while they are still pliable.
Let the cookies cool on the baking sheet for five minutes.
Then transfer the cooled cookie to a baking rack.
Measure out and bake the remaining cookies.
Melt the dark chocolate in the microwave or over low heat in a pot.
Spoon a blob of melted chocolate onto baking parchment, top with a cookie, and press down.
Allow the chocolate to set.
