  • 1 cup buttermilk
  • 1 tsp vanilla extract
  • 1 tsp baking powder

  • 1/2 tsp salt

Instructions

Peanut Butter Jelly Cake

Preheat and Prepare

Start by preheating your oven to 350°F. Grease your 9-inch cake pan and line the bottom with parchment paper for easy removal. This ensures your cake doesn’t stick and comes out perfectly every time. Tip: For an extra layer of flavor, lightly dust the pan with flour after greasing.

Mix Dry Ingredients

In a large bowl, whisk together the flour, baking powder, baking soda, and salt. This not only combines them evenly but also aerates the flour, leading to a lighter cake. Ensuring these are well mixed prevents any uneven rising or dense spots in your finished cake.

Cream Butter and Sugar

Using an electric mixer, cream together the softened butter and sugar until light and fluffy. This should take about 3 minutes. Add the peanut butter and mix until fully incorporated. The mixture should be smooth and slightly increased in volume, which is key for a tender crumb.

Add Wet Ingredients

Beat in the eggs one at a time, then stir in the vanilla. Alternate adding the dry ingredients and buttermilk to the butter mixture, starting and ending with the dry ingredients. This method ensures a smooth, well-incorporated batter without overmixing, which can lead to a tough cake.

Swirl in the Jelly

Pour half the batter into the prepared pan. Dollop half the jelly over the batter, then swirl with a knife. Repeat with the remaining batter and jelly. Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean. Tip: For a more pronounced swirl, don’t overmix the jelly into the batter.

Tips and Tricks

For those looking to take their peanut butter jelly cake to the next level, consider these advanced tips. First, toasting the flour before using it can add a nutty depth to the cake’s flavor. Second, using a high-quality, fruit-forward jelly can make the flavors pop even more. Third, letting the cake cool completely before slicing ensures clean cuts and perfect presentation. Fourth, a sprinkle of sea salt on top before serving can enhance the peanut butter flavor. Lastly, for a professional finish, a thin layer of peanut butter frosting can be applied to the cooled cake.

Recipe Variations

  • Swap out the peanut butter for almond or cashew butter for a different nutty flavor.
  • Use different jellies or jams, such as raspberry or blackberry, to change up the fruit component.
  • Add chocolate chips to the batter for a peanut butter and chocolate twist.
  • Incorporate crushed peanuts into the batter or sprinkle on top for added texture.
  • Make it gluten-free by substituting the all-purpose flour with your favorite gluten-free blend.

Frequently Asked Questions

Can I use natural peanut butter?

Yes, you can use natural peanut butter, but keep in mind it may alter the texture slightly due to its oil content. For best results, stir the peanut butter well before using to ensure it’s evenly mixed.

How do I store the cake?

The cake can be stored at room temperature, covered, for up to 3 days. For longer storage, refrigerate for up to a week. Just be sure to bring it to room temperature before serving for the best flavor and texture.

Can I make this cake ahead of time?

Absolutely! This cake actually tastes better the next day as the flavors have more time to meld. Just follow the storage instructions above and enjoy within the recommended time frame.
