Ingredients for Prune Cake Recipe with Buttermilk

Pantry staples meet nostalgic flavors in this tender Southern dessert classic.

The prunes are the soul of this cake—look for plump, moist pitted prunes (not the dry, shriveled kind). Sunsweet brand is reliable and widely available at most supermarkets. Buttermilk is non-negotiable for that signature moisture; Whole Foods or Trader Joe’s carry excellent full-fat versions. For the spices, Penzeys offers superior quality, but standard grocery store brands work if fresh.

No buttermilk? Stir 1 tbsp white vinegar or lemon juice into regular milk and let sit 5 minutes. Swap prunes for dried plums (same thing) or chopped dates if needed. Allspice can be replaced with pumpkin pie spice in a pinch. For nut-free versions, omit pecans or use toasted oats for crunch.

Store baked cake in an airtight container at room temperature for 3-4 days. For longer storage, wrap slices tightly and freeze for up to 3 months. Bring to room temperature before serving to restore full moisture and flavor.

Step-by-Step Instructions for Prune Cake With Buttermilk

Master this proven method for a perfectly moist cake with rich spiced depth every time.

Step 1: Prepare the Prunes and Pecans

Chop the 1.5 cups pitted prunes into small, even pieces to ensure they distribute uniformly throughout the batter. I use a sharp chef’s knife for precision—this prevents large chunks from sinking to the bottom during baking.

Next, chop the 0.5 cup pecans into coarse pieces for texture. Toast them lightly in a dry skillet over medium heat for 2-3 minutes until fragrant. This enhances their natural oils and adds depth. Set both prunes and pecans aside to cool before incorporating into the batter.

Step 2: Cream Butter and Sugars

In a large mixing bowl, beat the 0.5 cup unsalted butter (melted and cooled) with the 1.5 cups granulated sugar until fully combined. Use an electric mixer on medium speed for 2-3 minutes to achieve a smooth, creamy consistency.

This step aerates the mixture, creating a light base for the cake. The melted butter ensures a dense, moist crumb characteristic of traditional Southern cakes. Avoid overmixing, as this can incorporate too much air and alter the texture.

Step 3: Combine Wet and Dry Ingredients

In a separate bowl, whisk together the 2 cups all-purpose flour, 1 tsp baking soda, 1 tsp ground cinnamon, 0.5 tsp ground nutmeg, 0.25 tsp ground allspice, and 0.5 tsp salt. Sift if necessary to remove lumps and ensure even distribution of leavening agents.

Add the 2 whole large eggs, 1 cup buttermilk, and 2 tsp vanilla extract to the butter-sugar mixture, beating until just combined. Gradually fold in the dry ingredients, mixing until no flour streaks remain. Stir in the chopped prunes and pecans by hand to maintain their integrity.

Step 4: Bake to Perfection

Preheat your oven to 350°F. Pour the batter into a greased 9×13-inch baking pan and smooth the top with a spatula. Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.

The cake is done when the edges pull slightly away from the pan and the top springs back lightly when pressed. Avoid overbaking, as this can dry out the cake. The buttermilk ensures moisture retention, but timing is critical for the ideal texture.
