Heat oven to 410 °F.
Line two baking sheets with parchment paper and set aside.
Cream together butter and sugars. On my mixer I used my paddle attachment and set my speed to low for 30 seconds, medium for 30 seconds, and then high for 30 seconds. It came out creamed and fluffy.
Add eggs one at a time.
Add vanilla, cake flour, all-purpose flour, baking soda, maple extract, and mix for one minute until fully incorporated.
Fold in butterscotch chips and oatmeal cookies.
Scoop cookie dough onto the parchment paper (heaping scoop ~3T). Leave room in between the scoops. Cookies will spread a little as they cook. No need to flatten.
Repeat process. Do not overcrowd the sheet pan. I put ~4 cookies on a sheet pan.
Cook for ten minutes or until dough becomes golden brown.
Let rest for 3-5 minutes and ENJOY!
