Ingredients

  • 1 cup margarine
  • 1/4 cup cocoa
  • 1 cup water
  • 1/2 cup buttermilk
  • 2 eggs
  • 2 cups sugar
  • 2 cups flour
  • 1 teaspoon baking soda
  • 1 teaspoon vanilla

Instructions

  1. In a saucepan, combine margarine, cocoa, water, and buttermilk.
  2. Stir constantly over low heat until the mixture bubbles.
  3. Stir in sugar, flour, and baking soda while the mixture is hot.
  4. Beat until smooth, then stir in vanilla.
  5. Spread the batter into a greased and floured 9 x 13-inch pan.
  6. Bake for 25 minutes at 350°F (175°C) until the center is firm to the touch.
  7. Allow the cake to cool before serving.

Tips & Substitutions

For a richer flavor, consider using unsalted butter instead of margarine. If you're out of buttermilk, you can make your own by mixing regular milk with a tablespoon of vinegar or lemon juice and letting it sit for 10 minutes. To ensure even baking, always preheat your oven and check for doneness with a toothpick. This cake is similar in style to a Midnight Chocolate Cake but has its unique peanut butter twist.

Serving Suggestions

This cake is delicious on its own, but you can elevate it by serving it with a scoop of vanilla ice cream or a drizzle of chocolate sauce. For a fun twist, consider pairing it with Peanut Butter Party Cones for a themed dessert experience. Fresh berries or whipped cream would also make fantastic accompaniments to balance the richness of the fudge.

Storage & Reheating

Store leftover Peanut Butter Fudge Cake in an airtight container at room temperature for up to three days or in the fridge for up to a week. If you want to keep it longer, you can freeze slices for up to three months. To reheat, simply microwave a slice for about 15-20 seconds or enjoy it cold for a delightful treat.

Frequently Asked Questions

Can I use a different type of flour for this recipe?

Yes, you can substitute all-purpose flour with a gluten-free blend if needed. Just ensure that the blend includes a binding agent to help maintain the cake's structure. Keep in mind that the texture may vary slightly, so adjust the baking time if necessary.

How can I make this cake more chocolatey?

To make your Peanut Butter Fudge Cake more chocolatey, consider adding chocolate chips to the batter before baking. You can also increase the cocoa powder by an additional tablespoon or two, but be cautious not to overpower the peanut butter flavor.

Is there a way to make this cake vegan?

To make this recipe vegan, substitute the margarine with a plant-based alternative and replace eggs with flaxseed meal or a commercial egg replacer. Use almond or soy milk mixed with vinegar as a buttermilk substitute, and you’ll have a delicious vegan version of the cake!
