Equipment Needed

You’ll need a few basic kitchen tools to bring this delicious cake to life:

• A medium-sized saucepan for the chocolate mixture and frosting base.
• A large mixing bowl for combining the cake batter.
• A whisk and a spatula or wooden spoon for stirring and mixing.
• A 9×13 inch baking pan.
• An oven for baking.
• A cooling rack for the cake.

Instructions

Let’s get baking! The beauty of this cake lies in its simplicity, making it an ideal project for bakers of all skill levels.

1. Preheat and Prepare: Begin by preheating your oven to 400 degrees F (200 degrees C). Next, grease and flour a 9×13 inch pan. This crucial step ensures your cake releases cleanly, preventing any heartbreaking sticking incidents.

2. Create the Chocolate Base: In a saucepan, combine the 1/2 cup of margarine, vegetable oil, 4 tablespoons of unsweetened cocoa powder, and the 1 cup of water. Bring this mixture to a boil over medium-high heat, stirring often to ensure the margarine is melted and the cocoa is fully incorporated. Once it reaches a boil, remove it from the heat and set it aside to cool slightly. This warm, liquid chocolate base is the secret to the cake’s moistness.

3. Combine Dry Ingredients: In a large mixing bowl, sift together the 2 cups of all-purpose flour and the 2 cups of white sugar. Creating a smooth, lump-free base is key. Make a well in the center of these dry ingredients.

4. Incorporate the Chocolate Mixture: Pour the slightly cooled cocoa mixture into the well you’ve created in the dry ingredients. Begin to stir from the center outwards, gradually incorporating the dry ingredients into the wet until you achieve a smooth batter.

5. Add the Wet Ingredients and Flavorings: Now, mix in the 1/2 cup of buttermilk, the 2 teaspoons of vanilla extract, the 1 teaspoon of ground cinnamon, the 1⁄4 teaspoon of baking soda, and the 2 large eggs. Stir until everything is just combined and the batter is uniform. Be careful not to overmix at this stage; a gentle hand yields a tender cake.

6. Bake the Cake: Pour the batter evenly into your prepared 9×13 inch baking pan. Bake in the preheated oven for 20 minutes. To check for doneness, insert a toothpick into the center of the cake. It should come out clean when the cake is ready.

7. Cool Slightly: Once baked, allow the cake to cool slightly in the pan before you even think about frosting. This brief resting period helps the cake set and makes it easier to handle.

8. Prepare the Frosting: While the cake is cooling, let’s make the luscious frosting. In another large saucepan, combine the remaining 1/2 cup of margarine, the remaining 4 tablespoons of unsweetened cocoa powder, and the 5 tablespoons of milk. Bring this mixture to a boil, stirring often.

9. Finish the Frosting: Remove the saucepan from the heat. Now, stir in the 4 cups of confectioners’ sugar, the 1 cup of crunchy peanut butter, and the remaining 1 1⁄2 teaspoons of vanilla extract. Beat the mixture until the icing is smooth and well-blended. The peanut butter adds a wonderful depth and texture to this classic chocolate frosting.

10. Frost the Warm Cake: Pour the frosting over the warm cake. The heat of the cake will help the frosting spread beautifully, creating a glossy, irresistible topping.

Expert Tips & Tricks

• Cocoa Powder Matters: For the deepest chocolate flavor, use a good quality unsweetened cocoa powder. Dutch-processed cocoa will yield a darker color and a milder flavor, while natural cocoa will result in a brighter, more acidic chocolate taste. This recipe, as written, is quite forgiving with either.
• Buttermilk Shortcut: If you don’t have buttermilk on hand, you can easily make your own. For every cup of buttermilk needed, measure out 1 tablespoon of white vinegar or lemon juice into a liquid measuring cup, then fill the rest of the cup with milk. Let it sit for 5-10 minutes until it curdles slightly.
• Room Temperature Eggs: Ensure your eggs are at room temperature before adding them to the batter. This helps them emulsify more effectively, contributing to a smoother, more cohesive cake texture.
• Don’t Overbake: The 20-minute baking time is a guideline. Ovens can vary! Keep a close eye on the cake in the last few minutes of baking. Overbaked chocolate cake can become dry.
• Frosting Consistency: If your frosting seems too thick, add a tiny splash more milk (1 teaspoon at a time) until it reaches your desired spreadable consistency. If it’s too thin, gradually add more confectioners’ sugar.
• Peanut Butter Choice: While crunchy peanut butter adds a delightful textural contrast, feel free to use smooth if that’s your preference. The flavor will be just as incredible.

Serving & Storage Suggestions

This Wowie Chocolate Cake is best served slightly warm, allowing the frosting to be perfectly gooey. It’s a standalone star, but a dollop of whipped cream or a scoop of vanilla ice cream makes it even more decadent.

Leftovers can be stored at room temperature in an airtight container for up to 2 days, provided your kitchen isn’t excessively warm. For longer storage, refrigerate the cake in an airtight container for up to 5 days. To enjoy a slice after refrigeration, allow it to come to room temperature for about 30 minutes, or gently warm individual slices in the microwave for a few seconds for that freshly baked feel.

Variations & Substitutions

• Coffee Kick: For an intensified chocolate flavor, replace the 1 cup of water with 1 cup of strong brewed coffee.
• Dairy-Free Delight: While this recipe as written contains dairy, you could experiment with dairy-free margarine, plant-based milk (like almond or oat milk for the frosting), and an egg substitute if you have dietary restrictions. Note that this may alter the texture.
• Nut-Free: If you need to avoid peanut butter, you can substitute it with an equal amount of Biscoff spread or a dairy-free chocolate hazelnut spread for a different, yet equally delicious, frosting.
• Spice It Up: Add a pinch of cayenne pepper to the batter for a subtle Mexican chocolate twist, or include a bit of instant espresso powder to deepen the chocolate notes.

FAQs

Q: Can I make this cake ahead of time?
A: Yes, this cake can be made a day in advance. Store it at room temperature or in the refrigerator as per the storage suggestions.

Q: What if my frosting is too thick or too thin?
A: For a thicker frosting, gradually add more confectioners’ sugar, a tablespoon at a time. For a thinner frosting, add more milk, a teaspoon at a time, until the desired consistency is reached.

Q: Can I use oil instead of margarine in the frosting?
A: While margarine provides a certain richness and texture to this specific frosting, you could experiment with a neutral-flavored oil, though the consistency might change.

Q: How long does the cake last?
A: Stored properly, this cake will last for 2-5 days, depending on whether it’s kept at room temperature or refrigerated.
