Preheat the oven to 350°F (180°C). Line a cookie sheet with parchment paper and lightly oil the paper with oil spray. Set aside.
In a large mixing bowl, whisk all the dry ingredients: flour, quick oats, brown sugar, baking powder, salt, cinnamon. Set aside.
In another bowl, whisk the peanut butter (or egg), yogurt, maple syrup, vanilla extract, and melted coconut oil.
Pour the liquid ingredients onto the dry ingredients and stir to combine. The batter should be thick and dense.
Fold in chocolate chips, raisins, and nuts and stir to evenly combine into the cookie dough.
Oil your hand with coconut oil, scoop about 2 tablespoon cookie dough, and roll into a ball.
Place each ball onto the cookie sheet leaving one thumb space between each.
Slightly flatten the cookies with the palm of your hands - the thinner, the faster they bake and the less soft they are in the center.
Repeat the step above until all cookies are formed.
Bake on the center rack of the oven for 15-20 minutes until the cookies are golden brown.
Cool the cookies down for 10 minutes on the cookie sheet, then transfer them to a cooling rack.
