Step-by-Step Instructions
Preheat the Oven and Prepare the Baking Pan
First, set your oven to 350°F (175°C). While it warms up, grab an 8×8-inch baking pan. Line it with parchment paper, making sure some paper hangs over the edges. This makes it easy to lift the bars out later.
Combine Dry Ingredients
In a large bowl, add 1 cup of rolled oats, 1/2 cup of ground flaxseed, and 1/4 teaspoon of salt. Use a spoon to mix these dry ingredients well. Make sure they are evenly combined for a great texture.
Mix Wet Ingredients
Take a microwave-safe bowl and add 1/2 cup of creamy peanut butter and 1/4 cup of honey or maple syrup. Heat this in the microwave for about 20 to 30 seconds. Once warm, stir in 1/2 cup of mashed ripe bananas and 1/2 teaspoon of vanilla extract. Mix until it is smooth and creamy.
Combine Wet and Dry Ingredients
Pour the wet mixture into the bowl with dry ingredients. Stir them together until fully blended. If you want to add extra flavor, fold in 1/2 cup of mini chocolate chips and 1/4 cup of chopped nuts. This adds a nice crunch and sweetness.
Transfer Mixture to Baking Pan
Now, transfer the mixture into your prepared baking pan. Use a spatula or your hands to press it down evenly. Make sure it is compact and flat, so it bakes evenly.
Bake and Cool
Place the pan in your preheated oven and bake for 20 to 25 minutes. Look for golden edges and a firm center. Once done, take it out and let it cool in the pan for about 10 minutes. Use the parchment paper to lift the bars out and move them to a cutting board. Let them cool completely before slicing into bars.
- Suggested cool-down method: For a quick cool down, place the bars in the fridge for about 15 minutes. This will help them set better and make slicing easier.
Tips & Tricks
Substitutions for Peanut Butter
You can swap peanut butter for almond or cashew butter. This change still keeps the nutty flavor. If you want a nut-free option, try sunflower seed butter. Each choice brings its own taste and texture.
Storing Leftover Bars
To store leftover bars, first let them cool completely. Place them in an airtight container. You can keep them at room temperature for up to a week. For longer storage, pop them in the fridge. They can last for two weeks in there. You can also freeze them for up to three months. Just wrap them in plastic wrap or foil before freezing.
How to Test for Doneness
To check if the bars are done, look for golden edges. The center should feel set and not jiggly. You can also insert a toothpick into the center. If it comes out clean or with a few crumbs, they are ready. Avoid underbaking to keep the bars from being too soft.
Pro Tips
- Storage Tip: Store your Nutty Bliss Bars in an airtight container at room temperature for up to a week, or refrigerate for longer freshness.
- Banana Substitute: If you don’t have ripe bananas, unsweetened applesauce can be used as a substitute for moisture and sweetness.
- Custom Add-ins: Feel free to customize your bars by adding dried fruits, seeds, or your favorite nut butter for a unique twist.
- Cooling Tip: Allow the bars to cool completely in the pan before cutting to ensure they hold their shape when sliced.

Variations
Add-ins and Customizations
You can change up your peanut butter oatmeal bars in fun ways. Try adding dried fruits like raisins or cranberries. They add sweetness and chewiness. You can also mix in seeds like pumpkin or sunflower for added crunch. If you prefer a nutty flavor, add chopped walnuts or almonds. For a chocolate twist, toss in dark chocolate chunks instead of chips. Personalizing your bars makes them special and keeps them interesting!
Different Sweeteners Options
While honey or maple syrup works great, you can use other sweeteners too. Agave syrup is a lovely choice if you want a milder taste. You can even try coconut sugar for a deeper flavor. If you like a low-carb option, consider using stevia or monk fruit sweetener. Just remember to adjust the amount to fit the sweetness you like. Each sweetener brings its own unique taste to the bars.
Flavor Profiles to Explore
Spices and extracts can boost the flavor of your bars. A sprinkle of cinnamon adds warmth and comfort. If you want a zesty kick, try adding a bit of nutmeg. Vanilla extract makes everything taste richer. You can also explore almond extract for a nutty essence. For a tropical vibe, consider adding shredded coconut. These small changes can transform your peanut butter oatmeal bars into a delightful treat!
Storage Info
Tips for Proper Storage
To keep your peanut butter oatmeal bars fresh, store them in an airtight container. This helps prevent moisture and keeps the bars from getting stale. If you have a lot of bars, you can layer them with parchment paper. This way, they won’t stick together.
Freezing Peanut Butter Oatmeal Bars
Freezing is a great way to save these bars for later. First, let them cool completely after baking. Then, cut them into individual pieces. Wrap each bar tightly in plastic wrap or foil. Place them in a freezer bag or container. They stay fresh in the freezer for up to three months.
How Long Do They Last?
These bars last about one week at room temperature. Keep them in a cool, dry place. If you store them in the fridge, they can last up to two weeks. Just remember, the colder they are, the firmer they will get. Enjoy them at room temperature for the best flavor!
