Banana Chia Oat Jars Recipe

Updated Nov 24, 2025. Banana Chia Oat Jars are a healthy, clean, quick grab-and-go breakfast or snack. Prep them the night before for smoother mornings. In the colder months, I love warming this recipe for a cozy, protein-packed oatmeal breakfast. These oats are full of protein, healthy carbs, fat, and fibre — filling, nourishing, and budget-friendly. For an extra boost of protein, I added a clean, kid-safe protein powder (my favourite protein powder.) Grab more recipes in Trina’s Kitchen here.

Vegetarian, gluten and dairy-free, nut-free option

Oats — What to Use

Use unflavoured rolled oats, also known as quick oats. I prefer organic sprouted oats. Steel-cut oats don’t work for this recipe because they must be cooked first, but they’re a great option if you have time to cook them. If gluten is an issue, look for certified gluten-free oats since regular oats are often cross-contaminated.

Ingredients: 2 servings

1 ripe banana
1 cup rolled oats
6 tbsp chia seeds
½ tsp cinnamon
2 cups unsweetened plant milk
1 tsp cacao nibs
Optional: 2 servings of chocolate or vanilla plant protein powder and 2 tbsp nut butter or nut-free alternative

How to Make:

Slice banana thinly
Add ingredients to a bowl in the order listed above
Mix well *use the back of a measuring cup to smooth it out
Store in mason jars or a sealed container
Refrigerate overnight
Optional toppings: fruit, granola, coconut whip or cacao nibs

Trina’s Tidbits:

My daughter and I created this recipe together. If it’s too thick, add more milk. Use your favourite fruit and toppings to customize it. It’s a balanced mix of protein, fat, fibre, and carbohydrates — perfect to start your day strong.
