I rotate between dates overnight oats, banana chia seed oats, and cinnamon roll oats, with every batch turning out wonderfully rich and satisfying.

🥘Ingredients

- Rolled oats: It's best to use old-fashioned rolled oats for the perfect texture. Quick oats will work, but can turn out a bit mushy.
- Ground flaxseed (flaxseed meal): Always use ground flaxseed, since whole flaxseeds may pass through undigested and won't give you the same nutritional benefits.
- Peanut butter: Peanut butter adds creaminess and a boost of protein, and you can easily swap it with almond or cashew butter if you prefer.
- Maple syrup: Maple syrup naturally sweetens the oats, but agave syrup or date syrup are great alternatives.
- Plant milk: Use your favorite plant-based milk - almond, cashew, or oat milk all work beautifully.
As always, you can find the full recipe with a list of ingredients and measurements in a printable recipe card at the end of this post.
🥄How To Make Flaxseed Overnight Oats

Step 1: In a jar or airtight container, mix together rolled oats, ground flaxseed, peanut butter, maple syrup, and your favorite plant milk until well combined.

Step 2: Cover and refrigerate overnight (or at least 2 hours), then stir and add your favorite toppings before serving.

📋Variations
- Chocolate flax oats: Stir in 1 teaspoon cocoa powder and top with dark chocolate chips or cacao nibs.
- Berry bliss: Add a handful of fresh or frozen berries before refrigerating for a fruity, antioxidant-packed breakfast.
- Tropical twist: Use coconut milk as the base and top with pineapple, mango, or shredded coconut.
- Protein boost: Add a scoop of your favorite vegan protein powder and adjust the plant milk for creaminess.
💡Marinela's Tip
Always use ground flaxseed because whole flaxseeds won't be absorbed by your body and may pass undigested, so stick with ground for the fiber and omega-3 benefits.
