Preheat the oven to 350 degrees F/180 degrees C.
Soak the dates in a bowl with very hot water for 5 to 10 minutes while you gather the other ingredients. It doesn’t need to be boiling in my experience…you can just use the hottest setting from your tap. Drain after soaking.
In a food processor fitted with the S-blade, combine the soaked and drained dates, chickpeas, peanut butter, vanilla, salt, baking soda, and baking powder. Don’t add the almond flour yet. Blend thoroughly until smooth, about 1 to 2 minutes. Stop to scrape down the sides if needed.
Add the almond flour to the mixture. Blend again until smooth and well-incorporated.
Carefully remove the blade from the food processor. Stir ⅓ cup chocolate chunks into the batter. If the batter is hot from pulsing in the food processor for a while, it could melt the chocolate and cause the blondies to look darker. Let the batter cool before adding the chocolate if desired.
Line an 8x8 square baking pan with parchment paper, using chip clips or binder clips to keep the paper in place if needed. Spread the batter out in the pan, smoothing it out in an even layer as much as possible. It will be sticky.
Press the remaining 2 tablespoons of chocolate chunks on top.
Bake for 20 to 25 minutes until golden brown and a toothpick inserted into the center comes out clean.
Sprinkle with flaky salt after removing from the oven. Let the blondies cool for 10 minutes in the pan. Then, carefully lift the parchment paper up to transfer them to a counter or wire cooling rack to finish cooling. Let them cool for 45 minutes to 1 hour.
Transfer the parchment paper to a cutting board and cut the blondies into 16 squares. Enjoy!
