BOO! It’s Friday, it’s October, and that means I’m finally sharing some Halloween inspired treats.

You know what I love most about Halloween? No matter what age you are, it’s an excuse to dress up, have fun, eat candy, and just let the kid in you shine for a day. For someone who’s way too serious most of the time, this is so good for me. All month long I have so much fun being creative and making Halloween inspired treats, crafts, and of course, cocktails.

These bars are some of my favorites of the month for two reasons.

One, and most importantly, these bars are GOOD. Like so deliciously good. You all know I love the combo of chocolate and peanut butter. In fact I’ve been called out for using it too much…sorry, but not really because I love it!

Peanut butter and chocolate. Simple and Perfect.

Two, these bars are EASY. So, so, so easy. Easy enough that if you can make yourself a peanut butter sandwich, you can certainly make these bars. It’s true.

As mentioned, these are made using six pantry staple ingredients. Honey, maple syrup, peanut butter, chocolate, and white chocolate, that’s it. Yep, no additional sugar.

To make the bar base, melt together the honey, maple, and peanut butter until smooth and creamy. Stir in the corn flakes and dump the mixture out onto a baking pan.

Now add a very thick, even layer of melted chocolate (you can use dark, semi-sweet, or milk, use you favorite!). Next, take some melted white chocolate (use high quality, trust me it makes a difference) and dollop it in teaspoon and tablespoon size right over the chocolate. Grab a skinny stick (I used the end of a skinny spoon) and gently pull the white chocolate down to create a “ghost” shape (see above photo). Add eyes using sprinkles or melted chocolate.

Chill. Cut into bars.

See? Pretty easy, right?

And don’t stress about making these perfect. The more imperfect, the spookier they look.

Also, you will notice that my ghosts do not have mouths. I wish I could say this was intentional, but it was really just a careless mistake on my part. You know what though? I kind love these little guys just the way they are. They’re nothing close to a perfect looking ghost, but each is unique, ghostly, and fun.

Honest truth? No matter how much I would LOVE to be skilled in decorating beautiful desserts, it’s not my talent. I can’t pipe frosting all that well, I can’t make perfectly frosted sugar cookies with royal icing, and I am not going to spend five hours trying to make my Halloween treats look perfectly “spooky”.

Nope, I’m not a pro at decorating and I’m fine with that. Over the years I’ve learned to love and embrace the “imperfect” look. The awesome thing about Halloween treats is that the more imperfect they look, the better.

It’s all about that messed up, spooky vibe, so embrace your mistakes, especially with these bars. No one ghost should look another.

Above all, have fun and be creative with these! These bars are great for making with kids, and enjoyed by EVERYONE. You can pack them up and take them to the school Halloween party, or serve them at your adult filled Halloween bash.

Whatever route you go, these ghostly bars will be loved and devoured. Hence, making a double batch is highly recommended.

Recipe Notes

*These bars are GOOEY and we like them this way. If you'd like a bar that's less gooey, reduce the maple 1/4 cup and use 1/4 cup brown sugar.
