Peanut Butter Banana Clafoutis

This peanut butter banana clafoutis is the delicious result of having too many bananas while planning for this week’s reddit 52 week baking challenge. It’s a very Americanized version of a classic French dessert that’s both easy and elegant.

Clafoutis are made by layering fruit (traditionally cherries) into the bottom of a baking dish, covering the fruit with a custard, and baking. They’re served warm, usually dusted with confectioners sugar.

What else would you make with over-ripe bananas except for another loaf of banana bread?

Tips and tricks for this banana clafoutis

For this recipe, you can use any 9″ or 10″ pie pan, cake pan, or even cast iron frying pan. Butter the pan, sprinkle one tablespoon of sugar in the bottom, and then add the fruit in a single layer without overlap.

The batter will be liquid and the fruit may start to float. That’s ok. Try not to jiggle it around too much as you move it to the oven.

FAQs about this peanut butter banana clafoutis

Shouldn’t one clafoutis be spelled without the “s”?

Merriam-Webster seems to think so, but the French disagree.

How do you pronounce “clafoutis”?

Clah-foo-tee. The “s” is silent.

Do I need to refrigerate this clafoutis?

Yes, baked custards should be kept in the refrigerator. They will keep for a few days, though they are best served warm on the day they are made.

Can I make this without the peanut butter powder?

Yes. Just sub in the equivalent amount of flour.
