My absolute, go-to everyday breakfast is overnight oats, but not just any overnight oats… I prefer Protein Brownie Overnight Oats (and I’m pretty sure you will too). This is like eating dessert for breakfast but in the healthiest way! Plant-based and packed with protein and fiber. Other breakfasts you’ll love are Creamy Raspberry Chia Pudding, Veggie Frittata, and Sweet Potato Toast.
Why I Love This Recipe
- Protein-Packed: I use Wellious x HealthyGirl Chocolate Peanut Butter protein along with soy milk and whole-grain oats for a protein-packed breakfast.
- Healthy Breakfast: Starting the day with a balanced, nourishing breakfast is going to set you up for success to feel energized, satiated, and help avoid an afternoon crash.
- Meal Prep Friendly: I love overnight oats because they will store well in the fridge all week long. Make 4-5 jars have breakfast for every day of the week, swapping out the toppings each day.

Notes on Ingredients
- Oats: Use organic, whole, rolled oats. Opt for organic which will be better for the gut. Use these to make Snickers Baked Oatmeal next.
- Soy Milk: I like to use organic soy milk for its flavor and protein boost (8g in 1 cup) but any non-dairy milk will work. Try to use plain and unsweetened.
- Wellious Protein Powder: These Protein Brownie Overnight Oats use 1 scoop of Wellious x HealthyGirl Chocolate PB Protein for that delicious, chocolate fudge brownie flavor and texture. No chalkiness or weird aftertastes whatsoever.

Commonly Asked Questions
Overnight oats are typically eaten cold, but if you prefer them warm, you can just heat them in the microwave (or a pan) for a couple of minutes until warmed to your preferred texture. If you prefer warmed oats, try Berry Muffin Baked Oatmeal.
I use one scoop of Wellious x HealthyGirl Chocolate Peanut Butter protein. It’s seriously the best plant-based protein powder on the market. No chalky or grainy texture, no weird aftertaste, and absolutely no weird ingredients. It never bloats me either! It’s perfect in overnight oats, smoothies, baking recipes, in coffee, or even just blended with milk or water.
One serving of these oats has 30-35 grams of protein.
