Crunchy Milk Chocolate–Peanut Butter Layer Cake

Crunchy Milk Chocolate–Peanut Butter Layer CakeCrunchy Milk Chocolate–Peanut Butter Layer Cake (Adapted from Food and Wine)

For the cake

1 3/4 cups all-purpose flour
3/4 cup plus 2 tablespoons unsweetened cocoa powder
2 cups plus 2 tablespoons sugar
1 1/2 teaspoons baking powder
1 1/2 teaspoons baking soda
1 1/2 teaspoons salt
2 large eggs
1 cup milk
1/2 cup vegetable oil
1 tablespoon pure vanilla extract
3/4 cup plus 2 tablespoons boiling water

For the filling

1/3 cup sliced almonds
1/2 cup confectioners’ sugar
2 large egg whites
1 tablespoon granulated sugar
1/2 cup salted roasted peanuts, coarsely chopped
1 cup creamy peanut butter
2 tablespoons unsalted butter, softened
3 ounces milk chocolate, chopped
1 cup Rice Krispies

For the ganache

1 1/4 pounds milk chocolate, chopped
1 3/4 cups plus 2 tablespoons heavy cream, warmed

To make the cake

Preheat the oven to 350

In a large bowl, whisk together, flour, cocoa, sugar baking powder, baking soda and salt.

In a medium bowl, whisk the eggs, milk, oil and vanilla. Pour the wet ingredients into the dry and mix just until combined. Add the boiling water and stir until combined - the batter will be fairly thin. Pour the mixture into a 9" x 13" baking pan coated with nonstick spray.

Bake until a toothpick placed near the center of the cake comes out mostly clean with a couple moist crumbs attached, about 40 to 50 minutes. Remove from the oven and let cool completely. Turn the cake out of pan and place the cake, top side up, on a wire rack.

To make the filling

Reduce the oven temperature to 325

On a large piece of parchment, trace a rough 9" x 13" rectangle onto the paper and place it on a large baking sheet.

Add the almonds and confectioners' sugar into the bowl of a food processor - pulse until they’re finely ground.

In a medium mixing bowl, beat the egg whites at medium speed until soft peaks form. Add the granulated sugar and beat until the whites are stiff and glossy, about 2 minutes. Gently fold in the ground almond mixture. Scoop the meringue onto the parchment paper and use an offset spatula to fill out the outline you traced on the paper. Scatter the chopped peanuts on top. Bake until lightly browned and firm, about 15 to 20 minutes. Remove from the oven and let cool.

In a medium bowl set over a saucepan of simmering water, heat the peanut butter with the butter and milk chocolate, stirring constantly, until smooth and melted. Remove from the heat and fold in the Rice Krispies. Spread the mixture all over the meringue rectangle. Place in the freezer and let harden.

To make the ganache

In a medium bowl set in a saucepan of simmering water, melt the chocolate. Whisk in the cream until smooth. Remove from the heat and place the bowl into the refrigerate for 1 to 1 1/2 hours, whisking occasionally, until thick enough to spread.

To assemble the cake

Using a serrated knife, carefully slice the cake horizontally in half.

Place the bottom cake layer, cut side up, on a large board. Spread about one-third of the ganache over the cake. Invert the filling onto the cake and peel off the parchment paper. Spread half of the remaining ganache over the filling, then top with the second cake layer. Refrigerate until firm, at least 1 hour. Using a serrated knife, trim the edges. Spread the remaining ganache over the top and sides of the cake and refrigerate to set.

  5. Just made this yesterday - it's delicious! I don't think the directions mention where to put the chopped peanuts...? So I added them in with the Rice Krispies. The only other problem I had was that the cake was so moist and soft it fell apart, even when completely cool. Maybe I should have frozen it before I cut it. Anyway, everyone loved it. Thanks!

  6. Hi Leigh Ann - Thanks for the feedback!

    It does say where to place the peanuts - here is the passage.

    Scoop the meringue onto the parchment paper and use an offset spatula to fill out the outline you traced on the paper. Scatter the chopped peanuts on top.

  7. I made this tonight and I don't know what I did wrong - the meringue stuck terribly to the parchment, and the cake did not come out of the pan well. I have a pretty good pan and have never had this problem before. i was set to make another batch of the meringue and the cake but then I tasted a bit of the cake and it tasted so good, as did the meringue, that I broke up the cake, put half in a pan, poured some ganache over, then crumbled the peanuty meringue, poured the melted chocolate/peanut butter/rice crispie stuff on top, and then a bit more of the ganache, more cake chunks, and the rest of the ganache. I covered it well and then threw it in the fridge. I think it will taste wonderful, look pretty bad, but go over well. I'll let you know!
