What Was Julia Child’s Favourite Cake?

Julia Child is strongly associated with Reine de Saba, or Queen of Sheba cake, a French chocolate-and-almond cake. Sources discussing Child’s favourite desserts identify Reine de Saba as a particular favourite, although she also publicly named other chocolate desserts she loved.

What Was Elvis Presley’s Favourite Cake?

What Is the Most Delicious Cake in the World?

Taste is subjective, and therefore there is no objective “most delicious cake in the world”. Depending on texture, sweetness and cultural tastes, chocolate cake, cheesecake, carrot cake, pound cake and regional specialities can all be favourites.

What Is Heavenly Hash Cake Made Of?

Typically, Heavenly Hash Cake is composed of a dense chocolate cake, pecans or walnuts, mini marshmallows, and chocolate frosting. Family recipes vary in the type of flour, the size of the pan, the amount of cocoa used, and the ingredients in the frosting so that they can taste slightly different.

Introduction

If you want a dessert that combines a fudgy chocolate cake, crunchy pecans, soft marshmallows, and a rich chocolate topping, this heavenly hash cake recipe delivers all four in one pan. The cake has a brownie-like texture rather than a light sponge, making it especially satisfying for holidays, birthdays, potlucks, and family gatherings.

This version follows the traditional style found across several Southern recipes: a chocolate cake is baked in a rectangular pan, covered with miniature marshmallows while hot, and finished with a pourable chocolate frosting.

What Is Heavenly Hash Cake?

Heavenly Hash Cake is a rich chocolate dessert topped with marshmallows, nuts, and chocolate icing. It is closer in texture to a soft brownie than a fluffy layer cake, which is one reason the dessert works so well with its sweet, creamy topping.

Recipes vary from family to family. Some use pecans, some use walnuts, and the frosting can be made with evaporated milk or cream. Some versions also use a cake mix, while traditional recipes start from scratch.

The name can also be confusing because “heavenly hash” is used to refer to other desserts and candies. This article is specifically about the classic chocolate cake with nuts and marshmallows.

Ingredients You’ll Need

• 1 cup butter
• 2 cups granulated sugar
• 4 eggs
• 1 teaspoon vanilla extract
• 3½ tablespoons unsweetened cocoa powder
• 1½ cups all-purpose flour
• ½ teaspoon baking powder
• ¼ teaspoon salt
• 1½ cups chopped pecans
• 10½-ounce bag miniature marshmallows

Chocolate Topping

• 16 ounces powdered sugar
• 4 tablespoons cocoa powder
• 4 tablespoons butter
• 6–8 tablespoons evaporated milk

If you prefer the Southern-style ingredient list commonly found in older family recipes, self-rising flour can replace the all-purpose flour, baking powder, and salt. Pecans are the classic choice, but walnuts work if that is what you have.

Why the Marshmallows Matter

The marshmallows aren’t just for show. If the cake is hot, add them in to soften them and give the cake that characteristic creamy, chewy layer under the chocolate. Some recipes return the cake to the oven for a short time to let the marshmallows puff up, while others let the cake’s heat soften the marshmallows.

How to Make Heavenly Hash Cake

1. Prepare the Chocolate Batter

Heat the oven to 350°F and lightly grease a 9-by-13-inch baking pan. Melt the butter and allow it to cool slightly so it is warm rather than piping hot.

Whisk the eggs and sugar until blended, then stir in the melted butter, cocoa, and vanilla. Add the flour, baking powder, and salt, mixing only until the dry ingredients are incorporated. Fold in the chopped pecans. The finished batter will be fairly thick rather than pourable, like a conventional sponge cake batter.

2. Bake Until Just Done

Spread the batter evenly in the prepared pan and bake for approximately 30–40 minutes. Start checking toward the lower end of the range because ovens and pans vary.

The cake should be set in the centre without looking wet or liquid. Avoid treating it like a standard fluffy cake and waiting for an extremely clean toothpick; a slightly fudgy texture is part of the appeal.

3. Add the Marshmallows

As soon as the cake comes out of the oven, scatter the miniature marshmallows evenly over the surface. The heat from the cake will soften them.

For a more visibly swollen marshmallow layer, some traditional versions briefly return the cake to the warm oven. The goal is soft and puffy marshmallows, not deeply browned or burned ones.

4. Make and Add the Chocolate Frosting

While the cake bakes, prepare the topping. Combine the butter, cocoa, powdered sugar, and evaporated milk, adjusting the milk within the stated range until the frosting becomes smooth and pourable.

Pour the warm chocolate mixture over the marshmallow layer while the cake is still warm. Work gently so the topping spreads across the surface without completely flattening the marshmallows. Let the cake cool completely before cutting.

Tips for the Best Heavenly Hash Cake

Use the correct pan size. A scratch version made for a smaller pan can become disappointingly thin if spread into a much larger 9-by-13-inch pan. One competitor specifically warns that its smaller homemade formula is not suited to that larger pan.

Cool melted butter slightly. Very hot butter can affect the eggs when they are combined. Letting it cool for a few minutes makes mixing easier.

Don’t overbake. The ideal cake is rich and brownie-like. Baking until it becomes dry removes the contrast between the dense chocolate base and soft topping.

Prepare the frosting before the cake finishes. The marshmallows and icing are meant to go onto the hot cake, so having the frosting ready prevents unnecessary waiting.

Let it cool before slicing. The chocolate topping needs time to set, and cooling also makes the slices much neater.

Variations, Serving Ideas, and Storage

Pecans provide the traditional Southern character, but walnuts are an easy substitution. A cake-mix version is another shortcut used in some recipes when convenience matters more than making the chocolate base from scratch.

For serving, cut the cake into small squares because the combination of chocolate, marshmallows, nuts, and frosting is quite rich. Serve it at room temperature with coffee, tea, or a glass of cold milk.

For short-term storage at room temperature, keep the cooled cake covered if your kitchen is cool; refrigerate it for longer storage. Allow refrigerated pieces to sit briefly before serving so the frosting and marshmallow topping soften.

If the cake will be sitting out at a gathering, follow the FDA’s guidance on keeping perishable foods at safe temperatures. FDA food-safety guidance

Frequently Asked Questions

Can I use walnuts instead of pecans?

Yes. Walnuts are a practical substitute for pecans and work well with the chocolate and marshmallow topping. Use the same quantity unless you prefer a less nutty cake.

Can I use self-rising flour?

Yes. Many traditional Heavenly Hash Cake recipes use self-rising flour. If substituting it for all-purpose flour, baking powder, and salt, use the amount specified by the recipe rather than automatically adding extra leavening.

Why did my marshmallows disappear?

Marshmallows can soften substantially under the heat of the cake and frosting. For a more visible marshmallow layer, use miniature marshmallows and avoid leaving the cake in a hot oven longer than necessary.

How do I get clean slices?

Cool the cake completely before cutting, so the frosting can set. Use a sharp knife and wipe the blade between cuts for cleaner squares.

Final Thoughts

The appeal of Heavenly Hash Cake is its contrast: dense chocolate cake, crisp-tender pecans, pillowy marshmallows, and a smooth chocolate topping. It is simple enough for a casual gathering but distinctive enough to become a family favourite.

For the best result, pay particular attention to pan size, baking time, the timing of the marshmallow layer, and frosting consistency. Those details make the difference between a thin or dry cake and the rich, gooey dessert people expect from a traditional Heavenly Hash Cake.
