Ingredient Notes

- 1 tablespoon sugar: A touch of sweetness to balance the rich chocolate. You can adjust this based on your taste preferences.
Kitchen Gear Checklist
- Mixing bowl: For combining the chocolate and cream.
- Double boiler or microwave-safe bowl: To melt the chocolate gently.

Method: One Layer Fudge Cake

Step 1: Prepare the Cake Pan
Start by preheating your oven to 350°F (175°C). Line the bottom of a 9-inch round cake pan with parchment paper and lightly grease the sides. This will ensure your cake comes out easily after baking.
Step 2: Melt the Chocolate
In a double boiler over simmering water, or in a microwave-safe bowl in 30-second intervals, melt the finely chopped semisweet chocolate until smooth. Be careful not to overheat; stir frequently to prevent burning.
Step 3: Whip the Cream
In a separate mixing bowl, whip the heavy cream with the tablespoon of sugar until soft peaks form. This will give your cake that delightful fudgy texture.
Step 4: Combine Chocolate and Cream
Once the chocolate is melted and slightly cooled, gently fold the whipped cream into the chocolate. Use a spatula and be careful not to deflate the whipped cream too much. You want a light and airy texture.
Step 5: Pour into Cake Pan
Pour the chocolate mixture into the prepared cake pan, smoothing the top with a spatula.
Step 6: Bake
Bake in the preheated oven for about 25-30 minutes, or until the edges are set but the center is still slightly soft. This will help create that fudgy consistency.
Step 7: Cool and Serve
Let the cake cool in the pan for about 10 minutes before gently removing it and transferring it to a wire rack to cool completely. Once cool, feel free to dust with powdered sugar or serve with fresh berries for an extra touch.
Season-by-Season Upgrades
- Spring: Top with fresh strawberries or a berry compote for a light and fruity twist.
- Summer: Serve alongside a scoop of vanilla ice cream to complement the rich chocolate.
- Fall: Add a sprinkle of cinnamon or nutmeg to the chocolate mixture for a warm, spiced flavor.
- Winter: Drizzle with peppermint extract or crushed candy canes for a festive touch.
Slip-Ups to Skip
Here are some common mistakes to avoid while making your One Layer Fudge Cake:
- Overheating the chocolate: It can become grainy and lose its smooth texture.
- Not allowing the cake to cool properly: This can lead to a gooey mess when trying to slice.
- Skipping the parchment paper: It can be tricky to remove the cake from the pan without it.
- Over-whipping the cream: This can create a butter-like texture instead of the desired light fluffiness.
Prep Ahead & Store
This One Layer Fudge Cake is perfect for making ahead of time! You can bake it a day or two in advance and store it in an airtight container in the fridge. If you want to freeze it, wrap it tightly in plastic wrap and then aluminum foil. It can be frozen for up to three months. Just remember to let it thaw in the fridge before serving!
Helpful Q&A
Can I use dark chocolate instead of semisweet chocolate?
Absolutely! Dark chocolate will give a deeper flavor to the cake. Just keep in mind that it may be slightly less sweet, so adjust the sugar to your liking.
What can I use instead of heavy cream?
You can substitute with coconut cream for a dairy-free option, or use a heavy cream alternative available in stores. Just ensure it can whip up properly.
How do I know when the cake is done baking?
The edges should be firm, and the center should look slightly set but still jiggle a little when moved. It will continue to firm up as it cools.
Can I add toppings to the cake?
Definitely! Fresh fruit, whipped cream, or a drizzle of chocolate ganache all make excellent toppings for this One Layer Fudge Cake.
