Ingredients

Scale

For the Cake

  • Butter, for greasing the pan
  • 1 1/2 cups (190 grams) all-purpose flour
  • 1 1/2 teaspoons kosher salt (such as Diamond Crystal) or ¾ teaspoon fine salt
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon baking soda
  • 1/2 cup (113 grams) unsalted butter, softened
  • 3/4 cup (190 grams) smooth peanut butter
  • 3/4 cup (150 grams) granulated sugar
  • 2 large eggs, at room temperature
  • 1/2 cup (134 grams) sour cream
  • 1 tablespoon vanilla extract
  • 1/4 cup whole milk
  • 3/4 cup (188 grams) raspberry or strawberry jam

For the Swirl and Glaze

  • 1/4 cup (63 grams) raspberry or strawberry jam
  • 1 cup (100 grams) powdered sugar, sifted
  • 1/4 teaspoon kosher salt (such as Diamond Crystal)
  • 1/4 cup (57 grams) roasted salted peanuts, chopped

Instructions

  1. Prepare the Pan: Preheat your oven to 325°F (163°C). Butter an 8 ½-inch by 4 ½-inch loaf pan thoroughly, then line it with parchment paper leaving an overhang on the long sides. Butter the parchment as well to prevent sticking.
  2. Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, kosher salt, baking powder, and baking soda until evenly combined.
  3. Cream Butters and Sugar: In a large bowl or stand mixer fitted with a paddle attachment, beat the softened unsalted butter and smooth peanut butter on medium speed until very smooth, about 1 minute. Add the granulated sugar and continue beating until the mixture is noticeably lighter in color and fluffy, around 2 minutes.
  4. Add Eggs and Flavorings: Incorporate the eggs one at a time, beating each for about 30 seconds. Scrape down the sides of the bowl to ensure even mixing. Then add the sour cream and vanilla extract and beat for approximately 1 minute until the consistency is mousse-like.
  5. Incorporate Dry Ingredients and Milk: Add all the dry ingredients at once and beat on low speed until most of the flour mixture is incorporated. Avoid overmixing. Scrape down the bowl again, then add the whole milk and mix just until combined.
  6. Layer and Swirl Batter with Jam: Pour about one-third of the batter evenly into the prepared pan to cover the bottom. Spoon half of the 3/4 cup jam in small dollops over this layer—no need to spread. Add half of the remaining batter over the jam, then dollop the rest of the jam on top. Using a butter knife or wooden skewer, gently swirl the jam into the batter. Finally, add the remaining batter on top and smooth it into an even layer.
  7. Bake the Cake: Place the loaf pan in the preheated oven and bake for 1 hour to 1 hour 15 minutes. The cake is done when it starts to pull away from the sides and a toothpick inserted into the center comes out clean. Let the cake cool in the pan for 10 minutes before removing it and transferring it to a wire rack to cool completely.
  8. Prepare the Jam Glaze: Warm the 1/4 cup jam in a microwave-safe bowl for about 20 seconds or heat gently in a saucepan until liquefied. Strain the jam through a fine sieve to remove seeds and any solids. In a medium bowl, whisk together the jam, powdered sugar, and kosher salt until very smooth and pourable but thick. If the glaze is too thick, add water 1 teaspoon at a time.
  9. Glaze and Garnish: Drizzle the glaze evenly over the cooled cake, then sprinkle the chopped roasted salted peanuts on top for extra crunch and flavor.
  10. Serve and Store: Slice and serve the cake immediately, or tightly wrap leftovers to keep at room temperature for 3 to 4 days.

Notes

  • Room temperature eggs ensure better cake texture and volume.
  • Use smooth peanut butter for a creamier batter and more even consistency.
  • Lining the pan with parchment paper with overhang makes unmolding the pound cake easier and cleaner.
  • Swirling the jam gently avoids mixing it completely, preserving the jelly pockets inside the cake.
  • The glaze thickens as it cools—adjust with water to maintain a pourable consistency.
  • Storing the cake wrapped tightly at room temperature keeps it fresh for several days.
  • Roasted salted peanuts add textural contrast and enhance the peanut flavor.
  • You can substitute raspberry or strawberry jam with any berry jam of your choice.
