Mix the Wet Parts. Put butter and peanut butter in a bowl. Add both types of sugar in now. Beat them until they look very fluffy. This takes about three minutes of mixing.

Add Eggs and Vanilla. Crack your eggs into the sweet mixture. Pour in the vanilla extract slowly now. Mix again until the yellow disappears quickly. Do not overmix the dough at this step.

Stir in Dry Goods. Add the baking soda to the bowl. Pour in all of your quick oats. Stir them with a large spoon carefully. The dough will become very thick now.

Fold in the Treats. Add the chocolate chips and candy pieces. Fold them in with your rubber spatula. Make sure the candy is spread evenly. This ensures every cookie has chocolate inside.

Scoop the Dough. Use an ice cream scoop for balls. Place them on the baking sheet now. Leave two inches of space between them. This prevents the cookies from touching each other.

Bake to Perfection. Put the pans in the hot oven. Bake them for twelve minutes exactly now. The edges should look slightly golden brown. They will still look soft in the middle.

Cool the Cookies. Let them sit on the pan first. Wait about five minutes for them to firm. Move them to a wire rack later. This keeps the bottoms from getting soggy.
