This year for Halloween, I wanted to come up with a chocolate recipe that as many people as possible can enjoy, with keto, vegan, gluten free, oil free, nut free, and paleo options included.

Make up a big batch on Sunday, and take one from the freezer whenever a chocolate craving hits!

Do you have a favorite Halloween candy?

Each year if you google “most popular Halloween candy,” Reeses peanut butter cups beat out all of the other candy and chocolate bars on the market as everyone’s favorite Halloween candy.

It’s not even a close contest!

As a chocolate and peanut butter lover, I wholeheartedly agree Reeses are the best; and making my own at home not only saves packaging, it also means I get to decide what ingredients to use and how much sugar to add.

Because coconut oil melts at room temperature, use the melted chocolate option in the recipe instead of the coconut if not serving right away.

I brought the peanut butter bombs to a Halloween-themed picnic (we have a lot of picnics these days), and they were devoured by a group of monsters, pirates, ghosts, and vampires.

Also by one 5’3 hungry chocoholic giraffe.

Halloween is going to look a little different this year for sure, but thankfully there’s no rule that says you can’t still dress up and eat an abundance of chocolate.
