Trader Joe’s “Greatest and Easiest Chocolate Cake”: A Baker’s Best Friend

I still remember the first time I made this cake. It was a weeknight, I was exhausted, and the craving for chocolate was hitting me hard. I spied the recipe on the back of my Trader Joe’s Cocoa Powder container, and thought, “What the heck, I’ll give it a shot.” The ease of the recipe was a welcome surprise, and the resulting moist, intensely chocolatey cake was exactly what I needed. Now, years later, it’s my go-to when I need a reliable, delicious chocolate cake without a lot of fuss.

Recipe Overview

Prep Time: 20 minutes
Cook Time: 55 minutes
Total Time: 1 hour 15 minutes
Servings: 26
Yield: 2 cakes
Dietary Type: Vegetarian

Ingredients

3 1/3 cups flour
1 1/3 cups cocoa powder (the darker, the better!)
3 cups sugar
1 tablespoon baking soda
1 teaspoon salt
12 ounces (3 sticks) butter, softened
3 cups buttermilk
1 teaspoon vanilla extract
5 eggs

Equipment Needed

Two 9-inch round baking pans
Large mixing bowl
Electric mixer
Measuring cups and spoons
Rubber spatula
Toothpick or cake tester

Instructions

Preheat your oven to 350°F (175°C). Make sure your oven rack is positioned in the center.
Grease and flour two 9-inch round baking pans. Generously grease the pans with butter or cooking spray, then dust with flour, tapping out any excess. This ensures the cakes release cleanly after baking. Alternatively, you can line the bottom of the pans with parchment paper rounds.
In a large mixing bowl, combine all ingredients except the flour and buttermilk: cocoa powder, sugar, baking soda, salt, softened butter, and vanilla extract.
Stir the mixture until well combined. You can use a hand mixer or a stand mixer with the paddle attachment on low speed. Ensure there are no large lumps of butter remaining.
Stir in the buttermilk. Add the buttermilk to the bowl and mix until just combined. Don’t overmix at this stage.
Add the flour and beat with an electric mixer for 3 minutes, scraping down the sides of the bowl once during mixing. Be sure to scrape the bowl well to incorporate any flour that might be stuck to the sides and bottom. This ensures an even batter consistency.
Pour the batter into the prepared pans, dividing it evenly between them. Use a kitchen scale for perfect precision, or eyeball it and spread evenly with a spatula.
Bake for 55 minutes, or until a toothpick inserted into the center comes out clean. Start checking for doneness around 50 minutes. The baking time may vary slightly depending on your oven. A few moist crumbs clinging to the toothpick are okay, but there should be no wet batter.
Let the cakes cool in the pans for 10-15 minutes before inverting them onto a wire rack to cool completely. Cooling them in the pans slightly helps them retain their moisture.

Expert Tips & Tricks

Use high-quality cocoa powder. The flavor of the cake hinges on the cocoa, so spring for a good one. Dutch-processed cocoa will give a richer, darker flavor. Trader Joe’s cocoa powder is a great option, but you can experiment with others you love.
Room temperature ingredients are key. Make sure your butter and eggs are at room temperature for the best emulsion and cake texture. Set them out an hour or so before you plan to bake.
Don’t overbake. Overbaking is the enemy of a moist cake. Check for doneness with a toothpick, and err on the side of slightly underbaked if necessary.
Level the cakes. If your cakes dome significantly during baking, use a serrated knife to carefully level the tops before frosting. This will make stacking and frosting much easier.
For a more intense chocolate flavor: Add 1 cup of hot coffee or espresso to the batter along with the buttermilk. The coffee enhances the chocolate notes.
For a fudgier cake: Reduce the baking time by 5-10 minutes. The center will be slightly softer.
Make it a sheet cake: If you don’t have 9-inch round pans, you can bake this cake in a 9×13 inch pan. Reduce the baking time to approximately 40-45 minutes, checking for doneness with a toothpick. Note that the height of the cake will be reduced and may require adjustments to the frosting needed.

Serving & Storage Suggestions

This cake is fantastic on its own, but even better with frosting! A simple chocolate buttercream, a tangy cream cheese frosting, or a rich ganache are all excellent choices. Dust the top with cocoa powder or decorate with fresh berries for an elegant presentation.

Serving: Serve at room temperature for the best flavor and texture.
Storage: Store leftover cake in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week, or freeze for up to 2 months.
Freezing: To freeze, wrap individual slices tightly in plastic wrap, then place them in a freezer-safe bag or container.
Reheating: Thaw frozen cake in the refrigerator overnight or at room temperature for a few hours.

Dairy-Free: Replace the buttermilk with a dairy-free alternative like almond milk or soy milk mixed with 1 tablespoon of lemon juice or vinegar. Use a dairy-free butter substitute.
Chocolate Chips: Fold in 1 cup of chocolate chips (dark, milk, or white) into the batter before pouring it into the pans.
Espresso Cake: Add 1-2 teaspoons of instant espresso powder to the dry ingredients for a mocha flavor.
Spiced Chocolate Cake: Add 1 teaspoon of cinnamon, ½ teaspoon of nutmeg, and ¼ teaspoon of cloves to the dry ingredients for a warm, spiced version.

FAQs (Frequently Asked Questions)

Q: Can I halve this recipe?
A: Yes, you can easily halve the recipe for a single 9-inch cake. Just divide all the ingredients by two, and bake in one 9-inch round pan for approximately 45 minutes, or until a toothpick comes out clean.

Q: What if I don’t have buttermilk?
A: You can make a buttermilk substitute by adding 1 tablespoon of white vinegar or lemon juice to a liquid measuring cup, then filling it with milk to reach 3 cups. Let it sit for 5 minutes before using.

Q: Can I make this cake ahead of time?
A: Absolutely! The cake can be baked a day or two in advance. Wrap it tightly in plastic wrap and store it at room temperature. You can also freeze the cake for longer storage.

Q: My cake sank in the middle. What happened?
A: This can happen if the oven temperature is too low, or if the cake is underbaked. Make sure your oven is properly calibrated, and always check for doneness with a toothpick.

Q: Can I use a different size pan?
A: Yes, you can use other pan sizes, but you may need to adjust the baking time accordingly. A larger pan will require less baking time, while a smaller pan will require more.
