Start by lining a cookie sheet with parchment paper. Preheat the oven to 350 degrees.
Take the oatmeal and put it in the middle of the parchment paper. Mix in the honey, brown sugar, cinnamon, maple syrup, vanilla, and a pinch of salt on the top of the oatmeal.
Using your clean hands, mix the granola altogether until well blended.
Once you have it all mixed, take and spread out in a single layer on the parchment paper.
Put it into the oven and bake it for 10 - 15 minutes, or until the granola is golden brown.
Once done, take out of the oven and allow it to cool on a wire rack.
Next rinse the blueberries and let dry.
Once you've noticed that the granola is cool to the touch (still warm), take and put it in the bottom of a 9X9 pan lined with parchment paper. Press it down so it's even.
Then, take and place it in the freezer.
Grab a bowl and put in the blueberry yogurt, vanilla, and 1/2 cup of the blueberries. Then, mix well.
At this point, take the granola from the freezer, and put the Yogurt mixture right on top of it.
You should have some blueberries leftover so take and mix them with 2 Tablespoons of sugar and put them on top of the Yogurt.
Cover with foil and put it in the freezer overnight.
