I’ve been making this chocolate-peanut butter tart ever since Rose’s book came out–one year before I started Leite’s Culinaria! It was a staple of our entertaining table for a couple of years, which really isn’t so surprising considering The One’s favorite sweet combo is chocolate and peanut butter. He used to beg me to make it, and, of course, I’d shrug my shoulders and pretend to be disinterested, just to torture him, and then, in the end, carry one aloft into the dining room.

But over the past decade, various lovelies of the baking persuasion have lured me away, and this tart recipe, sadly, fell out of rotation. That was until Renee suggested we tip our hat to National Peanut Butter Day, which is January 24th. “I have the perfect recipe to celebrate with,” I said. While preparing the tart for the photo above, the whole shebang went off without a hitch, her meticulous instructions were like a siren whispering in my ear. Ah, the joys of an elegant and clearly written recipe.

HOW IMPORTANT ARE ACCURATE MEASUREMENTS IN BAKING?

You may be wondering why in baking, and in this recipe, in particular, measurements are so strictly measured. Like Rose Levy Beranbaum’s half an egg directive in the peanut butter crust, for instance. How can half an egg make a difference? Well, first, that’s just Rose. Second, that’s what’s made her such a standout cookbook author, and why mess with something that works? Baking, more than cooking, is scientific and you need the exact proportions to make things work.  The good news? That peanut butter crust recipe can easily be doubled and the second crust frozen for later. You’re welcome.

Ingredients 

For the peanut butter mousse

  • 7 tablespoons cream cheese
  • 1/2 cup peanut butter
  • 1/4 cup granulated sugar
  • 1 teaspoon vanilla extract
  • 3/4 cup heavy cream, softly whipped

For the milk chocolate ganache

Instructions 

Make the peanut butter mousse

  • In the bowl of a standing mixer, preferably fit with the whisk beater, beat the cream cheese, peanut butter, and sugar just until the mixture is uniform in color. Reduce the speed to low and add the vanilla. Beat in 1/4 cup of the whipped cream just until it is incorporated. With a large rubber spatula, fold in the rest of the whipped cream, mixing until the mixture is well blended but still airy.
  • Scrape the mousse into the sweet peanut butter cookie tart crust and smooth the surface so that it is level. (If the dough is rolled to the exact thickness specified, the filling and ganache amounts will be exact. If the dough is rolled a little thicker, there will be a little leftover filling and ganache.) Refrigerate the tart while preparing the ganache.

Make the ganache topping

  • Break the milk and bittersweet chocolates into several pieces and place in the bowl of a food processor fit with the metal blade. Process until the chocolate is very finely ground.
  • Bring the cream to a boil in a small saucepan over medium heat or in a heatproof glass measure in the microwave. With the food processor’s motor running, pour the hot cream through the feed tube into the chocolate mixture. Process until smooth, scraping the sides of the bowl once or twice, about 15 seconds. Add the vanilla and pulse a few times to incorporate it. Dump the ganache to a bowl. Cool to room temperature.

Assemble the tart

  • Pour the ganache over the peanut butter mousse in a circular motion, being careful so that it does not land too heavily in any one spot and cause a depression in the mousse. Using a small metal spatula, start to spread the ganache to the edges of the pastry, then spread it evenly to cover the entire surface of the tart. If desired, make a spiral pattern by lightly pressing the spatula against the surface and running it from the outside of the tart to the center. Refrigerate the tart for at least 2 hours to set or up to 5 days. (You can wrap the tart well and freeze it for up to 3 months.)
  • Remove the tart from the refrigerator at least 15 minutes before serving. Unmold the tart and cut it with a sharp, thin-bladed knife, dipping it in hot water after each slice. It is as good lightly chilled as it is at room temperature. Originally published January 23, 2011.

Recipe Testers’ Reviews

I’m enthusiastic about a lot of things, but I believe that taste buds evolved for the taste of chocolate and peanut butter combined. And only combined. This chocolate-peanut butter mousse tart is almost as easy as just smearing peanut butter onto a bar of good chocolate and having at it. The addition of a peanut butter cookie crust makes it some kind of fever dream for someone like me.

The instructions are spot on and everything comes together pretty quickly once you’ve gotten the crust finished. Speaking of the crust, double the recipe and freeze one—or just make it into cookies like I did. If you’re going to expend the effort to separate an egg, reward yourself with a couple of perfect cookies.

When reading the instructions, I unfortunately, skipped the part about the size of the pan and I ended up using something a little smaller. It still worked out just fine—I ended up being able to spread the crust higher up the sides so the filling all fit. And, other than the fact that I’m too clumsy for pretty ganache, my tart looked nearly spot-on. I served it a few hours after making it and the leftovers the following day were just as good. I’ll definitely make this again, especially that peanut butter tart crust. That might have been my favourite part.

  1. My tart pan is 11 inches–what’s a girl to do? Will the recipe stretch that extra inch? Should I use a 9-inch pie or cake pan instead? Make 1 1/2 times the recipe? Suggestions?

    1. Katherine, if you hold my feet to the fire, I’d say, yes, the 1 1/2 recipe will fit an 11-inch pan. But I haaaaaaaaaaaaaaate to say such things because I haven’t tried it personally. My suggestion: Double the recipe, that way you’ll definitely have enough dough. Then make cookies out of the leftover scraps.

  2. 5 stars
    Hi David (and the gang),

  3. Hey there I chanced upon this delightful recipe and I was thinking of baking it beforehand for a surprise birthday party. Do you think I can prepare the tart shell, filling, and ganache beforehand–say three to four days ahead? 🙂

    1. Farhanna, it IS a delightful recipe, I hope you try it! Yes, you can prepare everything in advance, provided you assemble the tart, refrigerate it a couple of hours until the various layers “set,” and then wrap it well and freeze it for the duration of time, as mentioned in step one under “Assemble the tart” in the recipe. You can allow it to thaw for several hours in the fridge. Let us know how it goes…!

      1. Thank you so much for your reply Renee! I’ll definitely try it. I’m keeping my fingers crossed everything will go according to plan!

        1. As are we, Farhanna. Please report back…and I meant to say earlier how lovely it is of you to bake something for the surprise party!

          1. Sure I will 🙂 Aww I’m only spreading the love for good food. The world needs a healthy dose of amazing tarts doesnt it!
