How to make these treats:

Let’s talk about how to make peanut butter rice krispie treats. (The printable instructions are in the recipe card below.)

Step 1:

First, spray a 13×9 inch baking dish with non-stick spray and set it aside.

Step 2:

Now add 6 cups of rice crispy cereal to a very large bowl and set it aside.

Step 3:

Next, take a large saucepan and add the butter, then melt over medium heat. After the butter has melted, add the marshmallows and peanut butter and melt. Stir frequently until it’s all melted.

Step 4:

Remove the pan from the heat and mix in the vanilla extract.

Step 5:

Now add the marshmallow mixture to the bowl with the rice krispie cereal and mix well with a large spoon or a silicone spatula.

You can spray the spatula or spoon with non-stick cooking spray and that can help. At some point though, you’ll probably need to use clean hands to mix if the mixture gets too firm.

Step 7:

Now spread the mixture into the sprayed 13×9 inch pan and press down a little.

Tips & FAQs:

Can I use the large marshmallows?

Yes, probably. I don’t think that would be a problem, just make sure the amount of ounces you use is the same that the recipe calls for.

Can I use margarine instead of butter?

That might work, but I can’t be sure. Butter will give you the best flavor though.

Should I use unsalted or salted butter?

Either works fine in this recipe.

Can I use natural peanut butter?

Maybe although I haven’t tried that out.

Do I have to use creamy peanut butter? Can I use chunky?

Yes, you can use chunky peanut butter if you prefer it.

Do I have to add the vanilla extract?

No. If you don’t have it, you can omit it.

Do I have to add the mini chocolate chips?

No. Feel free to omit the chocolate.

How do I store these and how long do they last?

Keep these treats in the 13×9 inch baking dish and cover with plastic wrap, or place squares into an airtight container. These treats are best eaten within 2-3 days.
