Preheat the oven to 355 degrees F (180 degrees C).
Soak your Pitted Dates (1 1/2 cup) in hot water for about 20 minutes to soften them. If your dates are moist enough, you may omit this step.
Place the Old Fashioned Rolled Oats (1/2 cup) in a food processor or high-speed blender and pulse until flour-like consistency forms. Depending on your blender or food processor, it should take less than 1 minute.
Add in the Peanut Butter (1/2 cup), Chickpeas (2 can), Baking Powder (2 teaspoon), Vanilla Extract (1 teaspoon), Salt (1 pinch), and dates in the food processor or blender. Pulse until a smooth cookie dough texture forms. Add in some plant-based milk or water, a tablespoon at a time if the batter is too dry.
Transfer the batter into a greased 8x8-inch baking pan. Smooth it out using a spatula.
Bake it in the oven for 20-25 minutes or until golden or a toothpick comes out clean.
Let it set in the pan for 10-15 minutes before transferring it to a cooling tray.
When the blondies are cooled to room temperature, spread the Peanut Butter (to taste) and top it with Peanuts (1 handful), if using. Slice and serve.
