Ingredients for Steel Cut Oat Bars
Learn how to make steel cut oatmeal bars recipe with 6 simple ingredients. This easy recipe can come together in under one hour.

- Steel-cut oats: Oats are heavily sprayed, so I recommend you buy organic oats to avoid potential glyphosate residue. If you are sensitive to gluten, make sure you use certified gluten-free oats. Even though oats are naturally gluten-free, they can be cross-contaminated with wheat during processing.
- Bananas: Go with overripe bananas with a few brown spots. Bananas are the only sweetener in these breakfast bars, so the riper they are, the sweeter the bars will be.
- Eggs: Used as a binder and a protein boost to hold all the ingredients together.
- Coconut flour: This gluten-free alternative adds texture and a satiety to the bars.
- Milk: Helps create a smooth batter and gives the bars a slightly creamy texture.
- Butter: Adds richness and moisture to the bars.
- Dried Cranberries or raisins: Provides sweetness, chewiness, and a burst of fruity flavor to complement the oats.
- Salt, baking powder, and vanilla: These baking essentials enhance the overall flavor and combine the finished taste.

Substitutions and Variations
- Add a crunch - Incorporate a crunchy element by adding chopped nuts such as walnuts, almonds, or pecans. It adds nutty flavor and fun texture.
- Increase sweetness - Add a natural sweetener like honey, brown sugar, or real maple syrup. Check out this post on other natural unrefined sweeteners.
- Fresh fruit - Fold in diced apples, pears, banana slices, or fresh blueberries into the batter.
- Make it chocolatey - Add a handful of chocolate chips.
- Deluxe breakfast bars - Make these steel cut oat bars extra satisfying by folding in a few tablespoons of chia seeds and a handful of coconut flakes for healthy fats and fiber.
💭Make it Nutrient-Dense: This recipe was originally published January 2016 and titled Soaked Oatmeal Breakfast Bars. It included instructions on how to soak oatmeal with buckwheat groats and an acidic medium for better digestion. You can still do that for maximum nutrient absorption but if you're in a pinch, just rinse them well under cold running water.

How to Make Steel Cut Oatmeal Bars Recipe
The complete printable recipe is below in the recipe card for your convenience. Follow these simple step-by-step instructions for the best results.

Step 1. Prep
Preheat oven to 350°F. Line a 9x13 baking pan with parchment paper and grease with coconut oil or butter. Set aside. Optional: Rinse the steel-cut oats in a fine mesh sieve under cold running water until the water runs clear. Leave them in the strainer over a bowl to drain well.

Step 2. Whisk
In a large bowl, whisk eggs using a hand mixer until foamy (approximately 4-5 minutes). Add bananas and mix until combined. Stir in milk, melted butter, and vanilla extract if using the liquid kind.

Step 3. Mix
In a small bowl, whisk all the dry ingredients (minus the cranberries) including coconut flour, salt, and baking powder together.

Step 4. Combine
Whisk in the dry ingredients into the wet eggs and banana mixture until thoroughly combined.

Step 5. Stir
Fold in the steel-cut oats and the dried cranberries or raisins if using. Add vanilla extract if you haven't already.

Step 6. Bake
Pour the entire mixture of steel cut oats into the prepared pan and bake until baked through and the toothpick inserted comes out clear.
Helpful Tips for Steel Cut Oat Bars
Soak for better digestion - Soak the oats in 4 cups of water, adding a ¼-cup of raw buckwheat groats, and 2 tablespoons of kefir, lemon juice, yogurt, or apple cider vinegar. Soak overnight to break down the phytic acid in the oats. Then rinse and drain very well before adding to the recipe.
Rinse well - While rinsing the steel-cut oats is optional, it can help remove excess starch, yielding a better texture. It also subtly softens the oats, kick starting the cooking process.
Use very ripe bananas - Since bananas are the only sweetener in these bars, make sure they are very ripe with brown spots on them. The riper they are, the sweeter the bars will be.
💭Meal Prep Suggestion: This recipe makes a big batch! Cut the steel cut oat breakfast bars into small individual servings and wrap tightly in parchment paper and plastic wrap. Freeze them and thaw as needed.
Serving Suggestions
Though these oatmeal bars with steel cut oats are great for breakfast, we use them as a satisfying and nutritious snack when we are on the go or mid-day. I am forever team eggs-and-steak in the morning like this pulled pork breakfast and the sheet pan breakfast. These oat bars are a good option to finish your heartier breakfast with. They don't offer a lot of sweetness but I find that's actually better if you're enjoying them with a sweet drink like pumpkin spice latte or hot chocolate.

Storage and Reheating Instructions
How long do steel-cut oat bars last?
To store: Store the bars in an airtight container at room temperature for up to 2 days. Then, transfer them to the fridge for up to a week.
Storage containers: These glass snap containers are perfect for baked steel-cut oats.
To freeze: Wrap individual bars tightly in plastic wrap and place them in a sealed freezer bag to avoid freezer burn. Freeze for up to 3 months. Remove a bar and reheat when you want to enjoy a quick breakfast or treat on the go.
To reheat: These bars are just as delicious cold but if you want to enjoy warm steel cut oatmeal bars, reheat them in a small toaster oven at 350°F for about 5-7 minutes or until they are warmed to your liking.

Frequently Asked Questions
Steel-cut oats are whole oat groats chopped into pieces, resulting in a chewy texture when cooked. Rolled oats are steamed and then flattened with large rollers, creating a flatter and quicker-cooking oat. The main difference lies in their processing, with steel-cut oats being less processed and having a heartier texture, while rolled oats are more processed and cook faster, offering a smoother consistency. Both variations retain the nutritional benefits of whole oats but differ in their cooking times and textures.
Technically yes, but I advise against it. Regular oats or quick oats have a finer texture, resulting in a softer and less chewy consistency compared to regular steel cut oats. This will significantly change the texture of the bars and the intended consistency. I recommend sticking to steel-cut oats for the best texture and flavor.
While soaking the oats is entirely optional it does help with better nutritient absorption and digestibility. The soaking process initiates enzymatic activity, breaking down anti-nutrients like phytic acid and making the nutrients more accessible to your body. Additionally, soaking can contribute to a creamier texture in the final product. So, if you have the time, consider giving your oats a soak for a more nutrient-dense and digestible steel cut oatmeal bars.

Vigorously whisk egg yolks, lemon juice and water in a small glass bowl. Place the bowl over a saucepan (or double broiler) with an inch of simmering water on low heat making sure bowl does not touch the water. Continuously whisking, the sauce should double in volume as the heat from the water gently thickens the egg yolks, approximately 5 minutes. Add butter, combining well after each tablespoon. If it gets too thick, add another teaspoon or so of warm water and whisk rapidly.
