  • Rolled oats: The star of the show, these provide a hearty, chewy texture and a good dose of fiber. They absorb water quickly so are good for baking.
  • Baking staples: Sugar, baking powder, cinnamon, salt, eggs, milk and vanilla extract.
  • Unsweetened applesauce: Not only does this keep the bars moist, but it also adds a subtle fruity flavor.
  • Optional Mix-Ins: Add anything you like, from nuts to dried fruit, or even a scoop of protein powder for that extra morning boost.

Variations

One of the best things about this recipe is its versatility. Here are some ideas for additional mix-ins to help you make the perfect oatmeal breakfast bars tailored to your taste:

  • Chocolate chips
  • Nuts (almonds, pecans, cashews)
  • Chia seeds or flaxseed
  • Dried fruit (like raisins or cherries)
  • Protein powder or collagen
  • Sunflower or pumpkin seeds
  • Shredded coconut
  • Peanut Butter (almond butter, cashew butter, sunflower seed butter)

How to Make Oatmeal Breakfast Bars

It only takes a few minutes of prep to make your dough, but it does need 20 minutes of resting time before baking, so make sure you factor that into your timing!

  • Whisk wet ingredients. In a large mixing bowl whisk the eggs, whole milk, unsweetened applesauce, and vanilla extract until smooth.
  • Combine dry ingredients. In a medium-sized bowl, mix rolled oats, granulated sugar, brown sugar, baking powder, kosher salt, and ground cinnamon.
  • Blend dry and wet ingredients. Add mix-ins if desired, then let it sit for 10 minutes before spreading the mixture into an 8×8-inch baking pan.
  • Bake and slice. Place oatmeal breakfast bars into the preheated oven and bake at 350°F for 30-35 minutes until edges turn golden brown. Cool for 5 minutes, then slice into bars.

Expert Tips

  • Let it rest. That 15-minute rest period after mixing the wet and dry ingredients isn’t just a suggestion. It allows the oats to absorb moisture and flavors to meld, resulting in bars with a wonderful texture and taste.
  • Don’t overbake. Keep an eye on your bars during that final baking period. You want the edges to be golden, but not overly brown. Slightly underbaking is better than overbaking, as it ensures a chewy, not dry, texture.
  • Customize to your heart’s content. Get creative with your mix-ins. Whether you’re a fan of crunchy nuts, sweet dried fruit, or a chocolate lover, these bars can accommodate your preferences.

Recipe FAQs

Can I double the recipe?

Yes, you can easily double the recipe if you want to make a larger batch of breakfast bars. Use a 9×13-inch baking dish instead of the 8×8-inch dish.

You may need to adjust the baking time slightly, so keep an eye on the baked oatmeal bars and extend the baking time by a few minutes if needed.

How can I tell when my oatmeal bars are done?

You’ll know your oatmeal bars are done when their edges turn golden brown, they feel firm when gently touched, a toothpick or knife inserted into the center comes out clean without wet batter, and the bars are not jiggly in the center. It’s better to slightly underbake them for a soft, chewy texture, as they’ll firm up a bit as they cool.

Can I make these bars in advance?

Absolutely! These bars are perfect for meal prep. You can whip up a batch over the weekend and enjoy them all week long. They even freeze well for longer storage.

Can I make them gluten-free?

Definitely! If you have a gluten sensitivity, just use certified gluten-free oats in the recipe. Everything else remains the same.

Are these bars kid-friendly?

Most definitely! Kids tend to love the sweetness and chewy texture of these oatmeal bars. Plus, they make a convenient, mess-free breakfast option for little ones

Storing

Storing your best oatmeal breakfast bars is a breeze. Here’s how to do it right:

Refrigeration: If you plan to devour these bars within the week, individually wrapping them and storing them in the refrigerator is the way to go. They’ll stay fresh and tasty for up to 5 days.

Freezing: If you’ve made a big batch or just want to have some on hand for those extra busy mornings, these bars are a dream to freeze. Individually wrap them and place them in an airtight container in the freezer. They’ll remain in perfect condition for up to 3 months.
