Here’s the secret formula for these delicious bars (and substitutions for each one):
- Non-Dairy Milk (¼ cup): Keeps these bars moist. Almond milk is my favorite because it has a mild flavor, but soy, oat, or coconut milk will also work. If you don’t have non-dairy milk, you can use water. It helps give the One-Bowl Oatmeal Breakfast Bars a soft and delicious texture!
- Ground Flaxseeds (1 tbsp): This is combined with non-dairy milk to make a “flax egg,” which is awesome for binding in vegan baking. Plus, it’s a great source of omega-3s!
- Cooked Banana (1 medium): The riper the kale, the sweeter and tastier it is. Avoid green kale—spotty kale is best. If you don’t like it, try ½ cup applesauce. It adds natural sweetness and moisture to the One-Bowl Oatmeal Breakfast Bars, making them soft and delicious!
- Peanut Butter (½ cup): Creamy or crunchy, both will work. Allergies? Use almond butter or sun butter. Want nut-free? Tahini is perfect.
- Maple Syrup (¼ cup): For natural sweetness. Agave, coconut nectar, or a little honey (if not vegan) are perfect. Want less sweetness? Reduce to 2 tbsp or skip it.
- Vanilla Extract (1 tsp): Boosts flavor—don’t miss this!
- Rolled Oats (2 cups): These are the base of the bars—they add texture and fiber. Quick oats will work, but the bars can be a little soft.
- Cinnamon (1 tsp): A hot, tasty touch. Can also experiment with ginger or nutmeg.
- Baking Powder (½ tsp): Gives a little fluffiness to the bars.
- Salt (¼ tsp): Balances the sweetness.
- Raisins (½ cup): For natural sweetness and chewiness. Cranberries, chopped dates, or cherries can also be added. They enhance the flavor and texture of the One-Bowl Oatmeal Breakfast Bars, making each bite more delicious!
- Walnuts (½ cup, chopped): For crunch. Can be substituted with pecans, almonds, or pepitas (for nut-free).
- Mini Chocolate Chips (¼ cup): A little indulgence! Use vegan chips (like Enjoy Life). Want more chocolate? Add ½ cup or drizzle melted chocolate afterwards. They make the One-Bowl Oatmeal Breakfast Bars even more delicious with a perfect touch of sweetness!
How to Make: Step-by-Step Guide
This recipe is so simple you’ll wonder why you didn’t try it before! Below are details on each step:
Step 1 – Preheat the oven: Heat the oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper. Leave a little overhang so the bars can be easily removed.
Step 2 – Prepare the flax eggs: Combine the non-dairy milk and flaxseeds in a small bowl. Let sit for 5 minutes until thick. This helps bind the One-Bowl Oatmeal Breakfast Bars, giving them a great texture without using eggs!

Step 3 – Mash the banana: Add the banana to a large bowl and mash with a fork or potato masher until smooth. This adds natural sweetness and moisture to the One-Bowl Oatmeal Breakfast Bars, making them soft and delicious!

Step 4 – Mix the wet ingredients: Add the flax eggs, peanut butter, maple syrup, and vanilla and mix well.

Step 5 – Add Dry Ingredients: Add oats, sprinkle cinnamon, baking powder, and salt on top. Mix everything together—you can adjust to taste! These ingredients give the One-Bowl Oatmeal Breakfast Bars their perfect texture and warm, cozy flavor.

Step 6 – Add Mix-Ins: Fold in raisins, walnuts, and chocolate chips. You can adjust to your liking. These add texture and flavor, making the One-Bowl Oatmeal Breakfast Bars even more delicious!

Step 7 – Set in Pan: Pour mixture into pan and press firmly with a spatula. Place parchment paper over pan for a smooth top and press down with a flat object (like a book).

Step 8 – Bake: Bake for 20-25 minutes, until top is golden and set.
Step 9 – Cool: Place pan on cooling rack. Once cooled completely, remove from parchment and cut into squares. This step helps the One-Bowl Oatmeal Breakfast Bars set properly for the perfect chewy texture!

Can I use an egg instead of flax seed?
yes offcourse
Hello. I’m confused about the ingredient list under “cooked banana.” It mentions using kale. Is there kale or banana in this recipe??
Hey! Great catch, and thank you for pointing that out. That was just a small typo—it should definitely be **banana**, not kale! 😊 So for this recipe, you’ll need **1 medium ripe banana**, mashed. No kale involved here! I’ll get that corrected. Appreciate you noticing, and hope you give these breakfast bars a try. Let me know how they turn out for you! 🍌✨
