With Valentine’s Day just around the corner, I figured it was high time for a new chocolate recipe here on the blog.

Even better, time for a new chocolate and peanut butter recipe here on the blog.

Because I’m pretty sure that chocolate and peanut butter were one of the original matches made in heaven.  And because I’m pretty sure that they were meant to be swirled together on top of this cake.  And because I’m pretty sure that the second you try a taste of them together in this decadent flourless cake, it’s going to be love at first bite.  :)

Even better, all you need are 5 easy ingredients to make this cake!  So grab your favorite chocolate, and let’s get to baking.

Really, this cake is just a peanut butter-y variation on my favorite 3-Ingredient Flourless Chocolate Cake recipe.  It’s surprisingly easy to mix together, and bakes in just half an hour.  Then once it has chilled completely, you can either just serve it as-is, or put your swirly cake decorating skills to use.  I promise — it’s much easier than it seems!

Just whip up a quick batch of chocolate ganache (melted chocolate + heavy cream), and pour it on top of the cake.  Then heat some peanut butter until it’s all melty, pipe it onto the top of the chocolate ganache into long zig zags, and then use a wooden skewer (or a knife or a toothpick) to swirl the peanut butter and chocolate into whatever kind of design you’d like.Peanut Butter Flourless Chocolate Cake -- made with just 5 easy ingredients, and so rich and delicious! | gimmesomeoven.com

So simple, and SO pretty!

You can either then just dive right into the cake, or refrigerate it awhile longer until the ganache completely sets up.  And then this decadent dessert will be yours to enjoy.

Peanut Butter Flourless Chocolate Cake

This peanut butter flourless chocolate cake recipe is made with just 5 easy ingredients, it's naturally gluten-free, and it is wonderfully decadent and delicious!

Ingredients:

Peanut Butter Flourless Chocolate Cake Ingredients:

  • 8 large eggs, cold
  • 1 pound (16 ounces) dark, semisweet or bittersweet chocolate, coarsely chopped
  • 1 cup (2 sticks) unsalted butter, cut into small pieces
  • 1/2 cup creamy peanut butter

Peanut Butter Chocolate Ganache Swirl Ingredients:

  • 3 ounces dark, semisweet or bittersweet chocolate, coarsely chopped
  • 1/3 cup heavy cream
  • 1/3 cup creamy peanut butter

Directions:

To Make The Peanut Butter Flourless Chocolate Cake:

  1. Adjust an oven rack to the lower-middle position and heat the oven to 325°F. Line the bottom of an 8-inch springform pan with parchment paper or waxed paper and grease the sides of the pan. (Be sure to grease the sides really well!)
  2. Place a large roasting or baking pan on the bottom rack of the oven.  Bring a kettle or medium-sized pot of water to boil on the stove.  Once it comes to a boil, carefully pour the water into the baking pan in the oven.  This will be your water bath, and will help prevent the top of the cake from cracking.
  3. While the water is coming to a boil, add the eggs to the bowl of a stand mixer.  Using the whisk attachment, beat the eggs at high speed until the volume doubles. This usually takes about 5 minutes.
  4. Meanwhile, melt the chocolate and butter and peanut butter together. You can either do this in a double boiler on the stove (by placing the chocolate and butter and peanut butter in a large heatproof bowl, set over a pan of almost-simmering water, and stirring until melted and smooth). Or you can do this in the microwave (by heating the chocolate and butter and peanut butter in a microwave-safe bowl in 30-second intervals, stirring in between, until the ingredients are melted and smooth). Then fold about a third of the beaten eggs into the chocolate mixture using a large rubber spatula until only a few streaks of egg are visible. Fold in half of the remaining egg foam, and then the last half of the foam, until the mixture is totally homogenous.
  5. Scrape the batter into the prepared springform pan and smooth the surface with a rubber spatula. Place the springform pan on the middle rack of the oven (a rack above the pan of boiling water). Bake until the cake has risen slightly, the edges are just beginning to set, a thin-glazed crust (like a brownie) has formed on the surface, and an instant-read thermometer inserted halfway into the center reads 140° F, about 23-26 minutes.
  6. Turn the oven off and crack the door oven open a few inches, and wait about 10 minutes for the cake to slightly cool.  Then remove cake and transfer to a wire rack, and cool until it reaches room temperature.  Then cover and refrigerate until the cake is completely chilled. (The cake can be refrigerated for up to 4 days.)
  7. Once the cake has chilled, carefully remove the sides of the springform pan, invert the cake onto a sheet of waxed paper, peel off the parchment paper, and then re-invert the cake onto a serving platter. Top with the peanut butter chocolate ganache swirl, if desired.  Or you can serve the cake lightly dusted with powdered sugar, or just plain.

To Make The Peanut Butter Chocolate Ganache Swirl:

  1. Melt the chocolate and heavy cream together in a double-boiler or in the microwave (use the same directions as above), and whisk together until the mixture is completely smooth.
  2. Add the peanut butter to a separate bowl, and heat in the microwave (about 15-25 seconds) until it is warmed and a little melty.  Transfer the peanut butter to a pastry bag or a large ziplock bag, and then use scissors to snip off a small corner of the bag so that you can pipe the peanut butter.  Set aside.
  3. Pour the chocolate mixture on top of the chilled cake, and use a spoon to spread it out in an even layer.  Pipe the melted peanut butter on top of the chocolate in some long lines (or your desired pattern).  Then immediately take a wooden skewer (or a toothpick or a knife) and drag it through the peanut butter in circles to create swirls.  If you'd like, you can then run a knife around the edge of the cake to smooth out the sides, or you can just leave it drippy.
  4. Refrigerate the cake for about an hour to let the ganache firm up, or you can just serve it immediately.

    Can this recipe be doubled? I would like to make it for my daughters bday party!

    • Hayley @ Gimme Some Oven — September 12th, 2016 @ 7:36 pm

      Hi Jill! We haven’t tried doubling this, so we can’t say for sure. However, this might work doubled in a 10-inch springform pan (it really needs to still be a springform pan though). If you have a 10-inch pan or can get one, we think it’s worth a try, we just can’t say definitively, unfortunately. We hope this is somewhat helpful!

    Yum, looks great! Can you post instructions on how to make those lovely swirls? Thanks!

    • Hayley @ Gimme Some Oven — September 13th, 2016 @ 9:36 am

      Thanks, Pearl — we hope you love it! The swirl instructions are actually already within the recipe.

      Just whip up a quick batch of chocolate ganache (melted chocolate + heavy cream), and pour it on top of the cake. Then heat some peanut butter until it’s all melty, pipe it onto the top of the chocolate ganache into long zig zags, and then use a wooden skewer (or a knife or a toothpick) to swirl the peanut butter and chocolate into whatever kind of design you’d like.

    Can I use semi-sweet chocolate chips for the chocolate, or should I use bars? Thanks! 

    • Hayley @ Gimme Some Oven — September 16th, 2016 @ 12:44 pm

      Hi Trinity! It’s totally up to you, but if you use bars, just make sure you’ve chopped them up well so they melt easily. We hope you enjoy this! :)

    I baked it for the time stated and it’s just no way it was done. I put it back in for an additional 10 minutes and it still seems runny and like it has nothing to bind to….
    Does it eventually set up as it cools or what could have went wrong? 

    • Ali — October 12th, 2016 @ 6:15 pm

      Oh no — not sure what went wrong there! It will definitely set up a little more as it cools, but shouldn’t be runny…

    I’m curious if you have tried a substitute for butter? I can’t have dairy but would still love to make this! Might coconut oil work? Thanks!

    • Hayley @ Gimme Some Oven — October 28th, 2016 @ 12:30 pm

      We haven’t tried this with anything other than butter, so we can’t say for sure! However, we think it’s worth a shot to give coconut oil a try. If you experiment with it, definitely let us know how it turns out! :)

    In your recipe for the cake there’s butter but butter is missing in your instructions to make….just eggs mixed to the choc and peanut butter mixture…where does the butter go ya..thanks.

    • Hayley @ Gimme Some Oven — November 22nd, 2016 @ 10:51 pm

      Hi Geraldine! It’s in step 4: Meanwhile, melt the chocolate and butter and peanut butter together.

      We hope you enjoy the cake!
