Pre-heat oven to 350°F. Lightly greasy or spray bottom and sides of a metal 9x13 baking pan.
In your stand mixer with wire whips, or a large bowl with a hand mixer, cream together 1 cup Peanut Butter and ¾ cup Sugar until fluffy (1-2 minutes).
To the mixer bowl, add ⅓ cup Real Maple Syrup, 1 Egg, and 2 T Coconut Oil and mix until well incorporated (2 minutes).
Mix in 1 tsp Real Vanilla Extract and ½ tsp salt.
If using a stand mixer, add the ⅔ cup Semi Sweet Chocolate Chips, then the 3½ cups quick oats and let run until well combined. If using a hand mixer, put it aside and add the chocolate chips and oatmeal by hand.
Press mixture into greased pan and push down hard until flat and smooth; using the bottom of a measure cup works great.
Bake at 350°F for about 15 minutes, depending on your oven. Watch the top and sides every minute starting at 15 minutes, when the sides are brown, and the top is set (not shiny) and doesn't smoosh down when lightly poked, remove from oven. That comes at 15 minutes in our oven.
Set pan on wire rack. Let cool in pan for 15 minutes to allow a firm set. Flip onto cutting surface and let fully cool.
Cut horizontally into 9 long bars, then one long cut down the middle. Or however you prefer.
Wrap completely in plastic wrap and store at room temperature up to 1 week. May be refrigerated up to 2 weeks and frozen up to 6 months (if freezing, wrap an extra layer over them to protect from freezer burn).
Notes
Use your preferred nut butter if you want to avoid peanut butter. Honey can be substituted for the sugar and/or maple syrup, but will result in texture and flavour changes. The ⅔ cup chocolate chips can be switched out for other preferred add-ins like other flavoured baking chips, seeds, nuts, and/or raisins or other dried fruits - see the post here for details.
