In a large bowl, whisk milk, chia seeds, and honey together. Cover bowl with plastic wrap and let set in fridge overnight.
In a medium-sized saucepan, heat blueberries and sugar over medium heat until they burst and become soft. Remove from heat and turn into a thick puree (with the help of a potato masher). Allow to cool.
Once the chia seed has set, start preparing your cups. Scoop your blueberry puree into your serving glass first, it will act as the base. Then fill the rest of your cup with chia seed pudding. Garnish with blueberries and enjoy!
