Frequently Asked Questions

How do I get clean slice cuts?

If you want pretty clean slices for these peanut butter bars, simply run your knife under hot water between cuts. 

Can I melt the ingredients in the microwave? 

I prefer combining my ingredients on the stovetop as the heat is distributed more evenly and I can stir it as it heats up. If you’re going to use the microwave, you’ll have to heat it up in short bursts and keep a close eye on it.

How do I store these no bake peanut butter bars?

Store these bars in an airtight container in the refrigerator for up to one week. You can also freeze them for up to 2 months.

Why did my chocolate topping crack when cutting?

This can happen if the chocolate is too cold. Let the bars sit at room temperature for a few minutes before cutting to prevent cracking.

Can I use natural peanut butter?

Yes, you can use natural peanut butter, but make sure it is well-stirred, as the oil separation can affect the texture of the bars.

    These were very simple to make and are delicious. I substituted honey for the maple syrup. My husband liked them because they were not too sweet. I did sprinkle some sea salt on them too. I will be making them again and these will be a good option for a last minute “what’s in the pantry” dessert.
