Healthy with Hollin LLC

Mornings can feel rushed—especially as a mom—but making sure breakfast doesn’t get skipped is something I really try to prioritize for both my family and myself. Having something nourishing ready to go takes a huge mental load off, and that’s exactly why this recipe has become a staple in our house.
These Cookie Dough Overnight Oats are prepped the night before, require minimal effort, and taste like a treat while still delivering the nutrients you need to power through the morning. All it takes is a container with a lid, a refrigerator, and about five minutes of prep.
Oatmeal is incredibly versatile, which means the flavor combinations are endless. This version leans into that nostalgic cookie-dough vibe while still being packed with fiber, protein, and healthy fats—making it a well-balanced, satisfying breakfast. This would be an ideal breakfast option a few hours before training since it contains fiber and healthy fats, slowing down digestion.
I especially love using my Weck jars for this recipe.
Why This Breakfast Works
The Power of Oats
Oats provide carbohydrates that digest more slowly, giving you a steady release of energy rather than a quick spike and crash. That makes them a great option an hour or more before training, or simply for keeping you fueled through a busy morning. They’re also a solid source of fiber, which supports digestion and helps keep you full longer.
Chia Seeds: Tiny but Mighty
Don’t let their size fool you—chia seeds bring a lot to the table. Just one tablespoon adds fiber to support gut health and fullness and omega-3 fats that support heart health and are considered anti-inflammatory which—great tip here for my athletes! Additionally, a bag of chia seeds lasts a good while, so you get a lot of bang for your buck.
In overnight oats, chia seeds also absorb liquid and help create that thick, pudding-like texture—so you get nutrition and better consistency.
Peanut Butter: Flavor + Fuel
Peanut butter does more than make this recipe taste like dessert. It contributes healthy fats for long-lasting energy as well as protein to support muscle recovery.
Pairing peanut butter with carbohydrates from oats is a great example of balanced fueling—it slows digestion just enough to keep energy levels steady.
Please don’t let the fat content scare you. There are different types of fats. Fats are essential just as carbohydrates, protein and fruits and veggies (color) are. Fats do so much for us including from a performance standpoint such as:
Provide sustained energy during low and moderate training
Assist in vitamin absorption
Provide insulation for organs
Play a role in recovery
Support hormone production—crucial for muscle repair.
One thing to make mention regarding fat is timing around training. Nutrient timing is very important when it comes to sports nutrition. You don’t want too high of fat content right before you train.
Greek Yogurt: Texture + Protein + Probiotics
Greek yogurt adds more than just creaminess to this recipe—it plays a big role nutritionally, too.
Greek yogurt is naturally higher in protein than traditional yogurt, which helps with muscle repair, satiety, and keeping blood sugar levels steady through the morning. It also provides calcium and phosphorus for bone health, plus probiotics that support gut health, digestion and contribution to an overall healthy immune system.
Yogurt is typically one of those food items that tend to have a lot of sneaky added sugar—I challenge you to look at the Nutrition Facts Label and find out for yourself. I use the vanilla-flavored Too Good brand which has 0 added sugar, but the vanilla flavor keeps things tasting indulgent along with the other ingredients such as the maple syrup and chocolate chips, so you truly don’t need a lot of added sugar when it comes to the yogurt itself. The tanginess of the yogurt pairs perfectly with the peanut butter + chocolate chips to give that true cookie-dough vibe.
Protein Powder: Convenient Support—Not a Replacement for Real Food
Protein powder helps boost the protein content of this recipe and makes it especially helpful for active mornings, post-workout fuel, or times when appetite is low but your body still needs nourishment.
That said, I always recommend a food-first approach before leaning heavily on supplements. Whole foods provide a wide variety of nutrients—fiber, vitamins, minerals, and beneficial compounds—that powders simply can’t replicate on their own.
Protein powder can be a useful tool for convenience, busy schedules, or higher training demands—but it shouldn’t replace balanced meals built from real foods whenever possible.
In this recipe, it works beautifully alongside oats, Greek yogurt, peanut butter, chia seeds, and milk to round out the protein content and help support muscle recovery, satiety, and steady energy through the morning. I especially love Momentous (use discount code HollinThompson) because it is third party tested and certified for sport and safe for athletes to consume.

With all of the ingredients in this recipe, it delivers a blend of carbohydrates, protein, and fats—the trio that helps keep you energized, satisfied, and ready to tackle the day.

This truly takes less than five minutes to throw together, which is part of why I love it so much. Minimal effort the night before = one less decision to make in the morning.
Prep time: 5 minutes
Serving size: 1
Ingredients
½ cup quick oats
1 scoop protein powder (I use Momentous)
1 tablespoon chia seeds
1 tablespoon chocolate chips (I use mini + dark chocolate)

Notes & Tips
No container with a lid? No problem—stir everything together in a bowl or jar and cover with foil before refrigerating.
Use cow’s milk for extra protein.

Top with fresh fruit for color, flavor, and micronutrients.
