When I first stumbled on this chocolate frosted peanut butter bar recipe, it was called Oh Henry! which is based on a candy bar of the same name. That bar has caramel and whole peanuts though, so I really didn't see the similarities. Since we had another "H" name in our midst, we renamed these bars after Hamish and they are now a party staple!
These bars hit all the right notes - chocolate and peanut butter are a super classic combo and ingredients we always have on hand.
You can work these around several different allergies. They are naturally gluten-free, just make sure your oats are certified GF if that's important to ya. You can use whatever chocolate chips you have on hand. I just wouldn't swap out the butter though. You really need that to hold them together so this won't be a dairy-free recipe.
If you're feeling sassy you could always press some m&ms or other fun candy into the top of the bars.
I've never tried other nut butters, but if you give it a go let me know in the comments.
This recipe makes a half sheet pan, so you'll have plenty to go around. They also freeze wonderfully, just make sure to cut them first. Since you've lined the pan with parchment you can cut it up to use it between layers of bars in your container, too.

I'm making these and after 15 minutes in the oven they seem to be very soft like batter soft. Do they harden up or do they need more time?
[email protected]
They do harden up. They can often look a little soupy.
Heather
What type of chocolate chips do you use? Semi-sweet or milk chocolate?
[email protected]
Semi-sweet but they would work with Milk Chocolate is that was your favourite.
Lisa
Could you replace the butter with an oil like avocado or olive?
[email protected]
You could replace the butter. I did with vegan butter. It didn't stay together as well but was as delicious.
