The basic recipe that I use is 1/4 cup oats, 1/4 cup yogurt, 1/3 cup of milk, 1 tsp of chia seeds, sometimes I add honey
The original recipe recommends plain greek yogurt and vanilla extract. I prefer to use regular vanilla yogurt.
Some of the variations that I've tried:
Pineapple coconut: In exchange for regular milk, you can use coconut milk and then add 1/4 cup of crushed pineapple.
I've also used mint chocolate coconut milk and 1/4 cup of chocolate chips.
Apple cinnamon: Add 1/4 applesauce and 1/2 tsp of cinnamon. Decrease the milk or it gets too runny.
Banana berry: add 1/2 sliced banana and 1/4 cup of blueberries or mixed berries
Pumpkin Pie: add 1/4 cup pumpkin, 1/2 tsp cinnamon, 1/4 tsp nutmeg
Peach: Add 1/4 cup of canned peaches or very soft peaches. May need extra liquid.
