Preheat your oven to 350 degrees Fahrenheit.
Using a hand mixer, cream together the soft butter, coconut sugar and vanilla extract for about 45 seconds, or until fluffy.
Add the tahini paste and egg and mix together using the mixer.
Grind your rolled oats in a blender until a coarse flour forms. You can also use storebought oat flour if you'd like.
Add half of the almond flour and oat flour and mix with the mixer until combined. Mix in the remaining almond flour and oat flour, as well as the coconut flour, baking soda and salt.
Fold in the candy gems and mini chocolate chips.
Use an ice cream scoop to scoop the dough into balls and place them on a parchment-covered cookie sheet about 2" apart from one another. The dough should make 16-18 cookies. Place the cookies in the oven for 8 minutes.
Remove the pan from the oven and gently tap the pan on the stovetop or countertop a few times. Place the cookies back in the oven and bake for an additional 6-8 minutes, or until the edges are slightly brown. Tap the pan on the stovetop or countertop once more when they come out of the oven to help them deflate slightly.
Allow the cookies to fully cool before enjoying. They will be slightly soft when they come right out of the oven but firm up as they cool.
