Preheat oven to 350 degrees F. Line a baking sheet with parchment paper.
Combine oil, honey & brown sugar in a microwave-safe bowl. Whisk well. Microwave for 60 - 90 seconds. Whisk again. Watch it so it doesn't boil over!
Add vanilla extract & pinch of salt. Whisk.
Line 8 graham cracker sheets on the parchment paper lined baking sheet. Pour honey mixture evenly over graham crackers. Spread evenly over the grahams with a spatula.
Bake for 10-12 minutes. When you pull this out of the oven, it will be a bubbly mess - you did it right! With a spatula, push the grahams back into a rectangle and push any extra caramel sauce back over the grahams. <The bubbly caramel will harden after it cools.>
Immediately, sprinkle with chocolate chips. Allow them to melt. It should take 2 - 3 minutes. Once melted, spread evenly with a rubber spatula. Sprinkle with M&M's and sprinkles.
Allow to cool completely. Then, chop into pieces and enjoy. Store in an airtight container.
