Start by melting the cacao paste in the microwave. Chocolate is very fragile and burns very easily, so you want to be extra careful when you do that. First, make sure that your chocolate is very finely and evenly chopped (the finer it is, the quicker it will melt) and place it in a microwave safe bowl (glass preferred). Then, place it in the microwave on high but make sure that you check on it and stir well every 20 to 30 seconds until it’s completely melted. This is very important as you do not want to burn your chocolate, and that can happen very quickly in a microwave. Chocolate will fully melt long before it gets truly hot, so do check on it often, and STIR!
When the chocolate is fully melted, which should take about 2 minutes total, add the salt and honey and stir delicately until smooth.
Divide half the melted chocolate between 15 large silicon muffin cups. You can use paper cups, but it’s a tad tricky, for paper is not quite sturdy enough to handle the task at hand. If you do choose to use paper cups, make sure you place them in a muffin pan to set.
Rotate and twirl each cup so that the chocolate covers the sides about ¾ of the way up. Flip them upside down over the bowl containing the melted chocolate to drip out any excess.
Divide half the crumbled bacon between the 15 chocolate coated cups. Place in the refrigerator until completely set, about 15 minutes.
Drop about a tablespoon of nut butter over the bacon and top with a banana slice. Slightly press on the banana to get the nut butter to come up on the sides a little bit.
Divide the rest of the chocolate between the 15 cups by pouring it right over the bananas. Again, rotate and swirl each cup until the chocolate completely covers the banana. Tap the cups a few times on the counter to make the top nice and smooth as well as to remove any air bubbles and fill all the nooks and crannies.
Garnish each cup with a few pieces of crumbled bacon and sprinkle with a pinch of Fleur de sel.
Place in the refrigerator to set for about an hour before taking the cups out of the silicon molds.
These chocolate cups will keep in the refrigerator for about 10 days in an airtight container
