分步操作

1. 1

   Preheat your oven to 175°C (350°F) and grease and flour a 9x13 inch (23x33 cm) baking pan.

   约 5分钟

   烹饪提示： Using parchment paper on the bottom of the pan will guarantee the cake doesn't stick.

2. 2

   In a large bowl, whisk together the all-purpose flour, granulated sugar, baking soda, and salt.

   约 2分钟

3. 3

   In a medium saucepan, combine the water, unsweetened cocoa powder, and cubed unsalted butter from the cake ingredients. Bring to a simmer over medium heat, stirring until the butter is fully melted and everything is combined.

   约 5分钟

   烹饪提示： Stir constantly to prevent the cocoa from scorching on the bottom of the pan.

4. 4

   Pour the hot chocolate mixture into the bowl with the dry ingredients and whisk until just combined.

   约 1分钟

5. 5

   In a small bowl, whisk together the buttermilk, beaten eggs, and vanilla extract from the cake ingredients.

   约 1分钟

6. 6

   Pour the buttermilk mixture into the batter and whisk gently until smooth. Be careful not to overmix.

   约 1分钟

   烹饪提示： Overmixing can result in a tough cake.

7. 7

   Pour the finished batter into the prepared baking pan and spread it into an even layer.

   约 1分钟

8. 8

   Bake for 22-25 minutes, or until a wooden skewer inserted into the center comes out clean.

   约 25分钟

9. 9

   Let the cake cool completely in the pan on a wire rack. This will take about an hour.

   约 1小时

   烹饪提示： Frosting a warm cake will cause the frosting to melt and slide off.

10. 10

    Once the cake is cool, carefully spread the creamy peanut butter over the top in an even layer.

    约 3分钟

    烹饪提示： If your peanut butter is very stiff, you can warm it gently in the microwave for 15-20 seconds to make it easier to spread.

11. 11

    In a medium bowl, whisk together the sifted powdered sugar, melted butter, buttermilk, and vanilla extract from the glaze ingredients until a smooth, pourable glaze forms.

    约 1分钟

    烹饪提示： If the glaze is too thick, add more buttermilk, one teaspoon at a time. If too thin, add more powdered sugar.

12. 12

    Pour the glaze over the peanut butter layer and use a spatula to spread it evenly to the edges.

    约 2分钟

13. 13

    Let the cake rest for at least 15 minutes to allow the glaze to set before slicing and serving.
