Chocolate Peanut Butter Bonbons

Chocolate peanut butter bonbons. Copycat Reese’s peanut butter cups. I don’t care what you call these chocolate bonbons with a peanut butter filling. Anytime you combine chocolate and peanut butter is a win in my book.

The background (feel free to skip)

This week’s reddit 52 weeks of baking challenge was chocolate, and my goal was to temper chocolate. I initially contemplated adding chocolate butterflies to the apple cake I made last week, but that might have been a bit much.

I next contemplated truffles. Mr. uglyducklingbakery gave me truffles for Valentine’s Day. But I’ve made truffles before.

And then I saw an Instagram bonbon.

FAQs about chocolate peanut butter bon bons

What’s the difference between a truffle and a bonbon?

Truffles have chocolate ganache centers, often rolled in cocoa or dipped in nuts. Bonbons are chocolate-encased and can include any sort of center. There seems to be a discrepancy whether the Venn diagram has truffles as a subset of bonbons or whether the sets are non-overlapping.

Do I have to temper chocolate to make chocolate peanut butter bonbons?

You can definitely dip things into chocolate that hasn’t been tempered. There are two things I took away from 8th grade home economics class – chocolate-dipped buckeyes and a purple stuffed elephant. But non-tempered chocolate doesn’t have the same shine or snap. For these bonbons, I would, and did, temper.

What are good resources for learning how to temper chocolate?

Here’s a good link from Epicurious on how to temper chocolate. More than anything, it just requires practice. And patience. Lots and lots of patience. And more practice.

I did have a temporary lapse of fortitude when I scooped a bit of the peanut butter filling onto a piece of chocolate. But onward I went.
