With a lot of kids in the house, I am always in need of snacks. If you have kids, I’m sure you understand.

I don’t like spending a lot of money on store-bought snacks, and I’m rather selective about ingredients, so making homemade snacks is the way to go!

These homemade granola bars have become an absolute staple for us.

Why You’ll Love Them

  • Making your own snacks is a fantastic way to save money. Pre-made snacks from the grocery store add up quickly, but the ingredients to make your own are usually much more affordable.
  • Homemade granola bars are completely customizable! You can swap out just about any of the ingredients to make a bar you’ll love and accommodate different dietary needs.
  • These granola bars are so easy! Easy to make and easy to eat. I love keeping granola bars in the fridge so we have something that is ready to enjoy as soon as we get hungry.

Ingredients

Homemade granola bar ingredients labeled on a white table.
  • Instant oats: I find instant oats to have a better texture than rolled oats in granola bars. They are more tender and easier to chew. You can substitute rolled oats if you prefer, but you’ll want to bake them first.
  • Butter: High-quality salted butter is best.
  • Peanut butter: Helps the bars stick together while adding protein and a delicious flavor. I used natural peanut butter (the kind you have to stir). You can use whichever peanut butter you like, but the thicker the better, so your bars hold up well!
  • Brown sugar: I like to use brown sugar in addition to the honey for a nicer texture and yummy caramelized flavor.
  • Honey: Honey provides the stickiness that holds the bars together, and a delicious flavor, of course.
  • Mini chocolate chips: My kids love mini chocolate chips in their granola bars! See the variations below for some alternatives.
  • Vanilla extract: This completes the flavor — trust me!

Variations

  • Swap out the chocolate chips for dried fruit, chopped nuts, or even a mix of seeds.
  • Add a dash of cinnamon or nutmeg to the oat mixture for extra flavor.
  • For a dairy-free version, use coconut oil or a plant-based butter substitute.
  • Rather than peanut butter, use your favorite nut butter, such as almond butter or cashew butter.

How to Make Homemade Granola Bars

Greasing a baking dish by rubbing oil into it with a paper towel.

Step 1. Grease an 8×10 baking dish and set it aside. Add the oats to a large mixing bowl.

Stirring a saucepan with melted butter and brown sugar in it.

Step 2. In a small saucepan, combine the butter and brown sugar. Bring to a low simmer, stirring until the sugar has fully dissolved.

Step 6. Scoop the mixture into your prepared pan. Use the bottom of a measuring cup or glass to firmly press it down until tightly packed. Chill in the fridge for 1-2 hours, then cut into bars.

Helpful Tips

  • Press the granola mixture down firmly and make sure it is well compacted so when it is time to slice, the bars hold their shape and do not fall apart.
  • I usually use natural peanut butter, but if you want that classic granola bar texture, regular peanut butter with a thicker consistency actually works even better.
  • Homemade granola bars can be stored in the refrigerator in an airtight container for up to a week.
  • When storing your granola bars, I recommend separating the layers with a piece of parchment paper or wrapping each bar individually so they don’t stick together.
  • Want to make more than a week’s supply at a time? You can freeze these granola bars for later!
  • I grease my baking dish with coconut oil or butter, but you can use another oil or cooking spray. You can also line the baking dish with parchment paper instead of greasing it.

Recipe FAQs

How can I make these nut-free?

You can swap out the peanut butter for sunflower butter, or omit it altogether. I’ve made these bars without the peanut butter, and they turn out great!

Do you have to bake homemade granola bars?

That depends on the recipe, but I do not bake my homemade granola bars! This simple no-bake recipe just requires melting some of the ingredients on the stove, then refrigerating the bars for a couple of hours.

How do I make these bars more crunchy?

The best way to make these crunchy is to pre-bake the oats. Just like you are making granola, mix the oats with a little bit of oil and bake them on low for 30 minutes. Allow the oats to cool completely before continuing with the recipe.

This is by far one of my favorite no-bake back-to-school snacks. It works great for breakfast or as a snack, which is perfect for me when I’m in a rush!

Of course, if I’m not in a rush, I’ll sometimes bake the oats first to give the bars a little extra crunch, but that doesn’t happen too often, haha!
