Drain the can of chickpeas over a sieve, give a quick rinse, and place them in the bowl of the food processor.
Add the peanut butter, oats, maple syrup, vanilla extract, and flaxmeal.
Blend on medium-high speed for 20 seconds. Stop the food processor, scrape the sides and bottom of the food processor bowl with a spatula.
Process again for 30-45 seconds or until the dough is smooth. If not, you can scrape down the bowl again and repeat the processing steps in 30-second bursts. It can take 3-4 times before the dough comes together. It should be sticky, but form a dough that you can press in your hand into a ball.
If too wet, blend in an extra tablespoon flaxmeal, or oats until the consistency is right.
Fold in mini dark chocolate chips, pulse a few times to incorporate.
Transfer the chickpea cookie dough to a piece of parchment paper.
Place another piece of parchment paper on top and press to flatten. I use a jam lid to press the top evenly. Form a rectangle shape.
Peel off the top piece of parchment paper.
In a microwave-safe bowl, add the dark chocolate and coconut oil. Microwave in 30-second bursts, stirring between each, until fully melted.
Pour on top of the bar and spread with a spoon.
Slide the bar - using the piece of parchment paper - onto a large plate.
Pop the plate 15 minutes in the freezer or until the chocolate layer is hard, but still easy to cut.
Slice into 7 bars.
