Mix the protein powder with the milk in a shaker bottle first. This helps you avoid powdery protein clumps.
Place the oats in a jar or bowl. Add chia seeds (or flax meal) to the oats, if using. Add the yogurt and pour the mixed protein into the bowl. If adding fruit, add it now or before serving. Mix well.
Refrigerate:
Refrigerate for at least 4 hours or overnight.
Serve:
In the morning, enjoy cold or warmed up for 30 to 60 seconds in the microwave, topped with your favorite toppings.
Notes
The thickness (in consistency) of the overnight oats will vary depending on the type of protein powder used. Plant protein powders tend to yield a thicker mixture than whey protein and might need a tablespoon or two more liquid.
Greek yogurt or regular can be used, with Greek yogurt providing more protein and a creamier texture.
Macros will vary depending on the milk, protein powder, and yogurt used.
Toppings & Add-Ins:
Nuts or seeds: opt for unsalted raw chopped nuts & seeds.
Fruit: both fresh and frozen fruit work. Can be added to the oats or on top. Bigger fruits should be sliced.
Nut butters: peanut butter, almond butter, and seed butters are great for topping or added into the mixture. You can also add 1-2 tablespoons of PB powder.
Spices: ¼ teaspoon per serving of cinnamon or pumpkin pie spice works great. Vanilla extract (¼ teaspoon) will be delicious too.
