Heat oven to 350 degrees. Prepare a cookie sheet by lining with parchment paper.
Use the paddle attachment of a stand mixer to cream butter, coconut sugar, and peanut butter. Mix until fully creamed. About 1-2 minutes.
Add the eggs and vanilla extract. Mix together.
Add in the oat flour, oats and baking soda. Mix until combined.
Fold in candy drops and chocolate chips.
Dump dough onto cookie sheet and spread out. It is a ton of dough, and will spread very far. You want it to be less than an inch thick.
Bake for 18-20 minutes, but not longer. If middle seems doughy, trust that it will continue baking as it cools.
Allow to cool for at least 20 minutes before slicing. Store in airtight container at room temperature, or freeze for up to one month.
