Morning Sickness Chocolate Overnight Oats for First Trimester (Tastes Like Brownies!!)

There were mornings in my first trimester when the nausea would come in waves, but my body still begged for something grounding. That’s when I discovered overnight oats. They became my lifeline.

These creamy chocolate oats felt like a treat—smooth, indulgent, and gentle enough on my queasy stomach. The cocoa gave me that little comfort boost I was craving, while the oats quietly worked in the background, keeping me full and steady without the sugar crash.

Why These Pregnancy and Postpartum-Friendly Chocolate Overnight Oats Are Good For You & The Baby

Oats were also my secret weapon against constipation, one of those first-trimester symptoms no one warns you about until you’re living it. Mixing them with yogurt added creaminess and a probiotic boost my body needed.

Some mornings, I’d even stir in a spoonful of my Antioxidant-Rich Homemade Chocolate Hazelnut Spread for extra richness, or I’d switch things up altogether with Pumpkin Spice Overnight Oats when I wanted warmth and coziness.

It became a little ritual of listening to what my body needed that day.

Prep Time: 5 minutes / Total Time: 5 minutes + overnight chilling / Yields: 1 serving

Ingredients (This is It!)

For the oats:

• 1/2 cup old-fashioned rolled oats
• 1/2 cup oat milk
• 1/4 cup plain Greek yogurt
• 1 tablespoon unsweetened cocoa powder
• 1 tablespoon maple syrup (or 2 teaspoons light or dark brown sugar)
• 1/2 teaspoon vanilla extract
• 1 tablespoon Homemade Chocolate Hazelnut Spread (optional)

For the toppings:

• 1/2 banana, sliced
• 1 tablespoon dark chocolate chips

Preparation Instructions for Chocolate Overnight Oats for Pregnancy

1. In a small jar or bowl, add the oats, oat milk, Greek yogurt, cocoa powder, maple syrup, and vanilla extract. Whisk until everything is fully combined. If using, stir in the optional chocolate hazelnut spread.
2. Cover the jar or bowl and place it in the fridge for at least 4 hours, or preferably overnight.
3. The next morning, the oats should be thick and creamy. Give them a good stir. If they are too thick, you can add a splash more oat milk.
4. Top with the sliced banana and dark chocolate chips. Enjoy cold!

Tips For the Best Pregnancy-Safe Chocolate Overnight Oats

• More toppings: 1/2 tablespoon toasted coconut flakes, dried cranberries, chopped pecans, or a drizzle of Homemade Constipation-Relief Peanut Butter adds great flavor and texture. 
• Use superfoods: Stir 1/2-1 tablespoon chia seeds or flax seeds into the oat mixture for extra nutrients. You can also use them as toppings!
• Berry delicious: Add 1/4 cup sliced strawberries, fresh raspberries, blueberries, or blackberries to your oats for some fruity tartness.
• Adjust the consistency: Once out of the fridge, give the oats a good stir. If too thick for your liking, add 1/2-1 tablespoon of additional oat milk to adjust the consistency. 
• Make it dairy-free: Swap the Greek yogurt for coconut or almond yogurt, or more oat milk. 
• Prep ahead: Double or triple the recipe (without toppings) and refrigerate each serving separately. Breakfast prep for the week will be ready in less than 15 minutes!

How to Store these Pregnancy Chocolate Overnight Oats

• Fridge: The prepared oats (without toppings) can be stored in an airtight container in the fridge for up to 4 days.

FAQs About These Chocolate Overnight Oats for Pregnancy & Postpartum

1. Can I eat overnight oats during pregnancy?

Yes! Overnight oats are safe and highly beneficial during pregnancy when prepared with pasteurized yogurt, milk, or plant-based alternatives (like this recipe!). They provide fiber to ease constipation, complex carbs for steady energy, and protein to help curb nausea from an empty stomach. Adding pregnancy-friendly toppings like banana, berries, or nut butters makes them both satisfying and nourishing.

2. Are chocolate oats safe for morning sickness?

Absolutely. Chocolate overnight oats can be a gentle way to satisfy sweet cravings without overwhelming a sensitive stomach. Cocoa powder provides antioxidants and a natural mood lift, while oats settle queasiness with slow-digesting fiber. Keep the cocoa unsweetened and the sweeteners light for the most stomach-friendly version.

3. How can I make these overnight oats more filling?

To make overnight oats more sustaining, stir in 1–2 tablespoons of chia seeds, flaxseeds, or nut butter. These healthy fats and fibers slow digestion, keeping blood sugar stable and preventing nausea from hunger crashes. Topping with Greek yogurt or adding protein powder also helps increase satiety.

4. Can I prep pregnancy-safe overnight oats for the whole week?

Yes—you can meal prep overnight oats up to 4 days ahead. Store each portion in an airtight container without toppings, then add fresh fruit, nut butter, or chocolate chips just before eating. This ensures freshness, prevents soggy toppings, and keeps your breakfast nausea-friendly all week long.
