Simmer - Combine honey and coconut oil in a medium pot. Bring to a simmer, and once pot starts bubbling up all over, start the timer for 1 minute. (See note 4)
Rest - When time is up, remove from heat and stir in the vanilla, salt, cocoa powder. Let it cool down for 10-15 minutes.
Prepare Pan- While the pot is cooling, prepare a 9x9 inch baking dish with parchment paper (binder clips and a spritz of oil can help hold it in place).
Add dry ingredients - After the mixture has cooled for 10-15 minutes, stir in the oats and chocolate chips until evenly coated. (*see note 5) Use a spatula to mix it in evenly. The chocolate chips might melt, but that's OK- it helps hold the bars together.
Press into pan -Press the granola bar mixture into the pan - HARD. You want to do multiple rounds with your spatula. You can also pop it in the fridge for 5 minutes, and do a second round of pressing. This is key to prevent bars from crumbling. Scatter a few extra chocolate chips into the top of the bars and press them in gently.
Chill- Cool in the fridge for 4 hours- overnight (overnight is best!), before slicing into bars.
