How to Make Chocolate Fudge Cake Squares

Preheat the oven to 350°F (175°C). Prepare a 9 × 13-inch casserole dish by greasing it and lining the bottom with parchment paper, ensuring an easy release of the cake.
Whisk together the flour, cocoa powder, sugar, baking powder, baking soda, and salt in a large bowl. Mixing these dry ingredients well will provide a smooth foundation for your cake.
Combine the eggs, vegetable oil, milk, and vanilla in the bowl with dry ingredients. Beat until the mixture is smooth; then, slowly stir in the hot coffee or hot water for an extra chocolate boost.
Pour the batter into your prepared casserole dish. Bake in the preheated oven for 30–38 minutes, checking with a toothpick until it comes out with a few moist crumbs.
Cool the cake in the casserole dish for about 10 minutes before transferring it to a wire rack for further cooling. This step allows the cake to set perfectly before adding the ganache.
Heat the heavy cream in a small saucepan over medium heat until it’s steaming but not boiling. Pour the hot cream over the chocolate chips in a bowl and let it stand for 2 minutes to melt the chocolate.
Stir the mixture until smooth and glossy. If using, mix in the butter to enhance the gloss of the ganache.
Spread the ganache evenly over the cooled cake. Allow it to drip slightly over the edges for that delicious, indulgent look.
Garnish with chocolate shavings or grated chocolate while the ganache is still soft. This finishing touch adds not only elegance but also an extra treat!
Set the ganache for 30–60 minutes at room temperature or refrigerate for 20–30 minutes before slicing into squares for serving.

Optional: Serve with a scoop of vanilla ice cream for an indulgent dessert experience.

Make Ahead Options

These Chocolate Fudge Cake Squares are ideal for busy home cooks looking to save time during the week! You can prepare the cake part up to 24 hours in advance; just bake it as directed and let it cool completely before wrapping it tightly in plastic wrap and storing it at room temperature. The ganache can also be made ahead; simply refrigerate it in an airtight container for up to 3 days. When you’re ready to serve, reheat the ganache gently until it reaches a pourable consistency, then spread it over the chilled cake. This way, you’ll enjoy the same delicious, fudgy results with minimal effort!

Tips for the Best Chocolate Fudge Cake Squares

• Use Room Temperature Ingredients: Ensure your eggs and milk are at room temperature for a smoother batter that mixes better, leading to perfectly moist cake squares.

• Don’t Overmix: Once you add the wet ingredients to the dry, mix until just combined. Overmixing can lead to tough cake squares instead of the desired fudgy texture.

• Check for Doneness: Use a toothpick to check for doneness; it should come out with moist crumbs. If it comes out clean, the cake may be overbaked and dry.

• Cool Properly: Allow the cake to cool properly in the dish before adding the ganache. This ensures that the warm ganache doesn’t melt the cake too much.

• Garnish While Warm: Sprinkle the chocolate shavings on the ganache while it’s still warm for better adhesion, enhancing the visual appeal of your Chocolate Fudge Cake Squares.

Chocolate Fudge Cake Squares Recipe FAQs

What type of cocoa powder should I use?
Absolutely! For the best flavor in your Chocolate Fudge Cake Squares, I recommend using unsweetened cocoa powder. Natural cocoa powder (like Hershey’s) is great and gives that rich chocolate flavor. Avoid Dutch-processed cocoa, as it can alter the leavening process due to its acidity.

How should I store leftover cake squares?
You can keep uneaten cake squares in an airtight container at room temperature for up to 3 days. If you want to prolong their freshness, store them in the fridge for up to a week. Just wrap them tightly to prevent them from drying out!

Can I freeze these chocolate cake squares?
Absolutely! To freeze your cake squares, first, wrap them individually in plastic wrap. Then, cover them with aluminum foil. They’ll stay fresh for up to 2 months in the freezer. When you’re ready to enjoy, simply thaw them at room temperature—easy peasy!

What can I do if my cake turns out too dry?
If you find your cake is on the dry side, don’t worry! Next time, I recommend checking for doneness a minute or two earlier, as oven temperatures can vary. Also, ensure your measurements are accurate. If you’re using hot water instead of coffee, be sure it’s hot enough to enhance that moist texture.

Is this recipe suitable for those with nut allergies?
Very! This Chocolate Fudge Cake Squares recipe is nut-free unless you choose to incorporate nuts yourself for added texture. Always check the labels of your ingredients to ensure no cross-contamination occurs if allergies are a concern.

Would these cake squares be okay for my pets if I accidentally drop one?
No way! These cake squares are not suitable for pets. Ingredients like chocolate are toxic to dogs and cats, so make sure to keep fallen treats out of their reach and avoid any sharing of this decadent dessert with them.
