Now, gather all your ingredients and prepare them in the right amounts. That makes it so much easier and more fun and you're less likely to forget anything.
Chop almonds and nuts up and spread them on a baking sheet lined with parchment paper. Bake for 7-10 minutes and let cool off a bit.
Combine almond butter and rice syrup in a big bowl. Add rolled oats, rice flakes and nuts and stir well.
Line a small mould (25x20 cm) with parchment paper. Add the sticky mass and press down. That works well with a potato masher. Freeze for an hour.
Right before taking the bars out of the freezer, melt the chocolate. Chop the chocolate first, that makes it easier to melt and ensures even heat distribution. Fill a saucepan with a little water and heat it on low. The water should not boil, just gently simmer.Hang a melting pot over the saucepan so that the bottom of the melting pot does not touch the water. You can also use a heatproof bowl placed on top of the saucepan.Add the chocolate to the melting pot. Stir regularly until the chocolate is completely melted. Keep an eye on the temperature: the chocolate should not get hotter than necessary for melting (about 45°C/ 113°F).
Lift the frozen block by the parchment paper out of the mold and spread the chocolate. It will firm up very quickly on the cold block.
Cut into 12 bars and keep them in the fridge in an airtight container.
