Step‑by‑Step Instructions for 3-Ingredient No-Bake Peanut Butter Bars
Step 1: Combine Ingredients
In a mixing bowl, add 1 cup of creamy peanut butter, 1 cup of rolled oats, and ⅓ cup of honey (or maple syrup). Use a sturdy spatula to mix these three ingredients together until they are thoroughly blended into a smooth, dough-like consistency. This step should take about 3-5 minutes, and the mixture will look cohesive and well-combined.
Step 2: Prepare the Baking Dish
Line an 8×8 inch baking dish with parchment paper, allowing some overhang for easy removal later. This will prevent the peanut butter bars from sticking. Transfer the peanut butter mixture into the prepared dish, using your spatula to spread it evenly, ensuring that it’s compacted firmly into the base. The mixture should be level and smooth on the top.
Step 3: Chill to Firm Up
Place the baking dish in the refrigerator and allow the mixture to chill for at least 1 hour. This chilling time will help the bars set, making them easier to cut into squares. You’ll know they are firm when the top feels solid to the touch, and you can see the edges pull away slightly from the parchment paper.
Step 4: Cut and Serve
Once chilled, remove the dish from the refrigerator and carefully lift out the bars using the parchment overhang. Place them on a cutting board and use a sharp knife to cut them into desired sizes, usually squares or rectangles. The 3-Ingredient No-Bake Peanut Butter Bars are now ready to be enjoyed, either chilled or at room temperature.
Step 5: Store the Bars
To keep your peanut butter bars fresh, store them in an airtight container in the refrigerator for up to a week. Alternatively, they can be frozen for longer storage. Just make sure to separate layers with parchment paper to prevent sticking. Enjoy these scrumptious bars as a quick snack or dessert whenever the cravings hit!

3-Ingredient No-Bake Peanut Butter Bars Recipe FAQs
What type of peanut butter should I use?
Absolutely, I recommend using creamy peanut butter for a smoother texture that blends seamlessly with the oats. If you prefer crunchy peanut butter, it will still work but may change the texture a bit, adding delightful chunks.
How should I store the no-bake peanut butter bars?
To keep your delicious bars fresh, store them in an airtight container in the refrigerator for up to 1 week. If you want to enjoy them longer, wrap each bar individually in parchment paper and place them in a freezer-safe container or bag. They can be frozen for up to 3 months.
Can I freeze these bars? What’s the best way to do it?
Yes! Freezing these bars is very simple. After preparing the bars, cut them into pieces, as they will be easier to thaw once separated. Wrap each piece in parchment paper to prevent sticking and place them in a freezer-safe bag. When you’re ready to enjoy, just take out a bar and let it thaw in the fridge for about 30 minutes.
What should I do if my bars are crumbly?
If your bars turn out crumbly, don’t worry! This can happen if the mixture wasn’t mixed thoroughly. To fix this, return the bars to the mixing bowl, add a little more peanut butter or honey, and mix until you achieve a sticky dough-like consistency. After that, press the mixture back into the dish firmly and chill again.
Are these peanut butter bars suitable for my allergies?
These bars are naturally gluten-free when using gluten-free rolled oats. However, make sure to check the labels on all your ingredients, particularly the oats and peanut butter, to avoid any cross-contamination. If you or someone you’re serving has nut allergies, consider substituting the peanut butter with sunbutter or a similar alternative.
Can I add other ingredients to the recipe?
Very! These bars are incredibly customizable. Feel free to incorporate chocolate chips, chopped nuts, or a sprinkle of cinnamon to enhance the flavor. Just remember, if you add anything too wet, it might change the consistency, so adjust the other ingredients accordingly if needed.
