1. Combine dry ingredients (flour, baking powder, cinnamon, salt) into a bowl. Mix gently and set aside.
2. In a mixing bowl, mix together sugars and butter. Once they are mixed well, add eggs- one at a time.
3. Add vanilla and continue mixing.
4. Using a 1/2 cup measuring cup at a time, add dry flour mix to the wet sugar mix. Do this until all wet and dry ingredients are mixed.
5. Add in chocolate chips, cinnamon chips and oats. Mix well, using a wooden spoon or at a low speed if using a mixer.
6. Scoop dough onto a lined baking sheet. Parchment paper is the best product to use for cookies. Bake for 8-10 minutes or until edges are slightly brown.
7. Cool for a minute on the baking sheet before moving to a cooling rack. Store in an airtight container.
