How to Make Hostess Cake
- Prep the Oven and Pan: Preheat your oven to 325°F. Line an 8×8-inch metal baking pan with parchment paper, leaving a 2-inch overhang on each side for easy removal. If desired, secure the edges with ž-inch binder clips.
- Mix the Dry Ingredients: In a medium bowl, sift together 1 cup plus 1 tbsp all-purpose flour, â cup cocoa powder, ½ teaspoon baking powder, ½ teaspoon baking soda, ž cup granulated sugar, and Âź teaspoon salt. Whisk to combine thoroughly.
- Combine Wet and Dry Ingredients: Make a well in the center of the dry ingredients and add Âź cup oil, 1 large beaten egg, â cup milk, and 1 teaspoon vanilla extract. Whisk until blended, then slowly incorporate ½ cup hot coffee until smooth; the batter will be thin.
- Bake the Cake: Spread the batter evenly in your prepared pan using an offset spatula. Bake for 20-25 minutes or until a skewer inserted in the center comes out clean. Transfer to a wire rack and cool completely in the pan.
- Prepare the Marshmallow Cream: In a large heat-safe bowl, place 5 oz of marshmallows. Pour 3 tablespoons melted unsalted butter over the marshmallows. Microwave for 2-3 minutes on medium, stirring every 30 seconds. Once melted and smooth, let cool for 5-10 minutes.
- Whip the Cream: In a mixing bowl, whip 1 cup heavy cream with an electric mixer until it holds stiff peaks. Stir ½ cup whipped cream into the cooled marshmallow mix to loosen it, then gently fold in the remaining whipped cream.
- Layer the Cake: Using a serrated knife, slice the cooled chocolate cake in half horizontally to create two layers. Spread the marshmallow cream evenly over the bottom layer. Place the second layer of cake on top and refrigerate while making the ganache.
- Make the Ganache: Place 5 oz chopped semisweet dark chocolate in a heatproof bowl. Heat â cup plus 1 tbsp of heavy cream and 1 teaspoon honey or corn syrup until gently boiling. Pour this hot cream over the chocolate and let it sit for 2 minutes. Whisk until the mixture is smooth and glossy.
- Top the Cake: Remove the layered cake from the fridge and pour the ganache over the top, letting it drizzle down the sides. Work quickly, as the ganache will set fast over the chilled cake.
- Finishing Touches: Once the ganache has set, fill a piping bag with the reserved marshmallow cream. Pipe decorative loops across the cake in three rows. Slice, serve, and enjoy!
Storing & Reheating
Store your Hostess Cake at room temperature for up to 2 days under a cake dome or in an airtight container. If you need to keep it longer, refrigerate it for up to a week. For freezing, wrap individual slices solidly in plastic wrap and store in an airtight container for up to 3 months. When ready to enjoy, let it thaw at room temperature or pop it in the microwave for a quick warm-up. Remember, the texture may change slightly after freezing, but a minute in the oven can refresh its delightful taste.
Chef’s Helpful Tips
- Avoid overmixing the batter; gently combine ingredients until just mixed for a tender texture.
- Make sure your marshmallow mixture cools before adding whipped cream, or it will deflate.
- Use a serrated knife to cut the cake for even layers without tearing.
- Chill your mixing bowl and beaters when whipping cream for best results.
- If the ganache seems too thick, add a splash more cream to reach your desired consistency.
- This cake can be made in advanceâjust await the final ganache topping until the day of serving.
