Chocolate and peanut butter are a classic combo that never gets old, and it’s extra tasty in these Peanut Butter Granola Bars drizzled with melty chocolate and sprinkled with flaked sea salt. This granola bar recipe is naturally gluten-free and dairy-free, you’ll also find my vegan suggestions below. They’re simple to make with healthy ingredients and store well too.
The thing that makes these Peanut Butter Granola Bars extra tasty is the toasted oats. I got the idea from a peanut butter cookie recipe a friend sent me.
From there I tinkered with her recipe a bit to make them into these granola bars. They turned out so tasty and I love how well they keep in the freezer too.
Ingredients & Substitutions
- Oats – make up the base of these granola bars, but they’re extra tasty because they get toasted first. Regular rolled oats are what you want for this recipe. If you’re gluten-free, check the label to ensure your oats are certified gluten-free. Bob’s Red Mill makes gluten-free rolled oats and it’s labeled right on the front of the bag.
- Ground flax – holds these granola bars together a little better and adds fiber and Omega 3’s. The original recipe I posted called for whole flax seeds that you lightly toast. However, I’ve found ground flax seeds to be easier to use in this recipe!
- Honey – is the perfect pairing with peanut butter, but you could also try maple syrup or agave nectar as well.
- Peanut Butter – is my favorite flavor for these bars, but you can use almond butter or cashew butter if you can’t have peanuts.
- Avocado oil – or any other neutrally flavored oil works here. You can even use melted butter.
- Vanilla – rounds out this recipe and deepens the peanut butter and chocolate flavors.
- Chocolate Chips – get melted together with a touch of avocado oil to make the perfect chocolate drizzle over the peanut butter granola bars.
- Flaked Sea Salt – can be left out, but it’s so good sprinkled over the chocolate drizzle and really makes the flavors pop.
How to make this recipe step by step
Step 1: Start by toasting the oats until they’re golden brown. Then set them aside to cool on a wire rack.
Step 3: Add the oats when they’re room temperature or barely warm to the peanut butter mixture.
Step 4: Stir to completely combine the oats with the peanut butter mixture.
The mixture will be very thick.
Step 5: Line a half-sized cookie sheet with parchment paper and firmly pat the peanut butter oat mixture into the pan.
You can also use a regular-sized cookie sheet and pat the mixture only halfway across the cookie sheet. Spread the mixture is the thickness you want your granola bars to be.
Let the bars set at room temperature for 30+ minutes or pop them in the fridge to firm them up before cutting and drizzling with chocolate.
Step 6: If you’re using the chocolate drizzle, melt the chocolate chips together with the avocado oil over very low heat until just melted.
Step 8: Drizzle the bars with chocolate and let the chocolate set up partially before sprinkling with flaked sea salt.
Ways to serve this
- As a snack any time of the day!
- Cut these into squares and serve them for dessert, they’re rich enough and everyone loves the chocolate peanut butter combo.
- You can also serve the peanut butter oat mixture warm right out of the pan in dollops like a no-bake cookie and top it with your choice of vanilla ice cream or chocolate ice cream.
Many brands of granola bars aren’t very healthy, they’re basically candy bars chock full of sugar. The good news is they’re easy to make yourself with healthy ingredients and natural sweeteners like honey.
You can use any nut butter you like instead of peanut butter for this recipe. However different kinds of nut butter vary slightly in texture, so if the bars are too soft, you may need to add a few more oats.
- To store – when the chocolate drizzle has been set up, store the bars in an airtight container and refrigerate for up to 2 weeks. They get drier over time, so I suggest storing them in the freezer. From there you can pull out a few at a time to keep on hand in the fridge.
- Make ahead – these are the perfect make-ahead recipe because they keep so well in the freezer. Consider adding them to your meal prep to have on hand for quick snacks or a treat.
- To freeze – these freeze beautifully! When the chocolate drizzle has been set up, transfer them to an airtight container and freeze them for up to 6 weeks. You can also place these in the freezer to quickly firm up the chocolate before placing them into your container.
Tips & Tricks
- Don’t skip toasting the oats, it adds incredible flavor and texture!
- Keep a close eye on the oats in the oven so they don’t burn.
- You can also spread the chocolate mixture over the bars to create a ‘frosting’ if you want to serve these as desserts. That’s what I did in my original recipe, but I’ve switched over to a chocolate drizzle for a bit less sugar. That way these granola bars are a bit healthier, but they don’t sacrifice flavor.
Dietary Options & Substitutions
- Dairy-free – These granola bars are naturally dairy free as long as you use dairy-free chocolate chips like Enjoy Life.
- Paleo – There isn’t a good substitute for oats in these bars, so I recommend trying my Almond Butter Chocolate Chip Energy Bites instead. You can form that mixture into bars rather than bites if desired.
- Vegan or Vegetarian – Swap the honey for your choice of maple syrup or agave nectar and use vegan chocolate chips.
