In a mixing bowl, mix butter, vegetable oil and sugar with a hand mixer.

Add vanilla and salt.

Slowly add and mix the flour and baking powder into the bowl.

Add the egg and cinnamon powder and mix with hand mixer.

Then add the instant oats and mix completely by hand.

Place mixed dough on a work surface. It should be dry enough to work with.

Form the dough into a log shape of about 2 inches diameter. If it is sticky, sprinkle with flour.

Cut into ¼ to ½ inch disks.

Roll each disk into a ball and place them on a wire rack lined with parchment paper in a baking tray.

Pre-heat oven to 350 degrees F and bake cookie dough for 20 minutes.

Take it out and let it cool.
