  1. 1Heat the oven to 350°F and arrange a rack in the middle. Generously coat a Bundt pan with cooking spray.

To make the peanut butter swirl:

  1. 1Add the peanut butter, powdered sugar, melted butter, vanilla, and salt to a medium bowl. Using a whisk or hand-held blender, beat until completely smooth, about 3 minutes. Set aside.

To mix and bake the cake:

  1. 1In a saucepan, melt the butter and chocolate over low heat, stirring with a whisk. Add the cocoa powder and stir until smooth. Let this mixture cool, about 10 minutes.
  2. 2Meanwhile, whisk together the flour, baking soda, and salt to combine and break up any lumps; set aside. In the bowl of a mixer fitted with the paddle attachment, beat together the eggs and sugar on medium-high speed until light and fluffy, about 3 minutes. Add the sour cream, vanilla, and butter-chocolate mixture and stir on low speed until well combined, about 3 minutes. With a rubber spatula, stir in the dry ingredients just until combined. Scrape half the batter into the prepared pan.
  3. 3Drizzle half the peanut butter swirl into the batter, then drag a knife through it to swirl it into the chocolate batter. Scrape the remaining half of the chocolate batter over the top, and repeat swirling the peanut butter mixture into the batter.
  4. 4Bake until a toothpick inserted into the center of the cake comes out clean, about 40 to 45 minutes. Cool the cake in the pan on a wire rack for 
15 minutes, then unmold onto the rack and let the cake cool completely before glazing.

To glaze and finish:

  1. 1Warm the cream in a saucepan over low heat. Add the chocolate and corn syrup and stir with a whisk until the chocolate is melted and the glaze is smooth. Let the glaze cool to room temperature, then stir in the vanilla.
  2. 2Set the wire rack holding the cake over a sheet of parchment paper and pour the glaze over the top of the cake, letting it run down the sides. Slide the cake onto a serving platter and sprinkle with the chopped peanuts.
