Blend 1 cup of the old fashioned oats until they resemble flour. Pour into a bowl.
Blend the dates (soak in a bowl of warm water if they are hard and then drain and dry well) until a thick paste forms. Place in the bowl.
Add the almond butter, maple syrup, vanilla extract, salt, and cinnamon.
Add in the remaining 1 and 1/4 cup oats.
Using hand mixers blend until well combined. Add up to 1/2 cup additional oats. The mixture is quite wet, but it does set up a bit in the fridge. It's up to you and the texture you want for how many extra oats you add!
Line an 8 x 8 pan with parchment paper, foil, or plastic wrap.
Press the granola bar mixture evenly into the pan and place in the fridge to chill and set up for at least 1 hour.
Once the bars have set up, drizzle the glaze on. To make the glaze: combine the white chocolate chips and the coconut oil (measure when melted)
Microwave the mixture in 15 second bursts, stirring in between each burst for 10-15 seconds until completely smooth.
Stir in the vanilla extract, powdered sugar, and milk. Stir until a thick frosting has formed and transfer to a small plastic bag. Cut off the tip.
Remove the chilled bars from the fridge and cut into bars. Pipe the frosting onto the bars and allow to harden. (Return to the fridge).
Store in an airtight container in the fridge.
