Make the chia egg first. Mix 1 tbsp of chia seeds with 3 tbsp of water and let the chia egg rest for about 15 minutes to get a gel-like consistency. Grind the oats in a blender.
Add all dry ingredients into a mixing bowl: Oat flour, coconut blossom sugar, vanilla extract, baking powder, and salt and mix it together.
Mix the liquid ingredients: peanut butter, oat milk, and the chia egg, separately in a mixing bowl.
Combine the ingredients together. Now add chocolate chips. Knead the dough with your hands until you get a thick mass.
Take a heaped tablespoon, shape the dough into balls, or use an ice cream scoop. Put the balls on a baking tray lined with baking paper and press the cookies down.
The cookies should rather be soft and chewy, so let the cookies bake for about 9-10 minutes. Do you prefer the cookies to be crispier? Then the dough balls should be a little thinner and bake the cookies a little longer (up to 15 minutes).
The cookies must cool down for a few minutes. Otherwise, they will be too soft.
