Prepare the brussels sprouts by removing the outer leaves, washing, cutting off the stem and cutting in half.
Place brussels sprouts in a bowl, add oil and garlic powder
Spread brussels sprouts onto baking sheet and roast for 20 minutes, stirring halfway through.
While brussels sprouts are roasting, boil balsamic vinegar and red pepper flakes in a small saucepan for 10-15 minutes or until vinegar is a thick reduction.
Drizzle balsamic reduction over the brussels sprouts and serve warm

You will know the reduction is done when the consistency resembles a thin syrup and does not have a strong vinegar taste anymore.
I recommend adding the balsamic glaze to the brussels sprouts immediately. If you allow the glaze to sit and cool, it will get firm and very sticky.
If you accidently over reduce your balsamic vinegar and it become too thick and sticky, add more vinegar and allow it to come to a simmer until it has thinned out again.
You can also purchase balsamic glaze and add the red pepper flakes to it to make this step easier, but I think having the balsamic vinegar and red pepper flakes cook together brings out the spice more.
