Food History
Heavenly Hash has been a popular treat in the United States since the early 20th century. It traditionally involves marshmallows, chocolate, and nuts. Over the years, many variations have evolved, including this bar version that turns the classic combination into a layered dessert perfect for parties and family gatherings.
Recipe Discussion
The base layer of the Heavenly Hash Bars starts with a simple chocolate batter made from oleo (a type of margarine), eggs, and chocolate syrup, providing a deep, rich flavor. Vanilla enhances the chocolate, while flour and baking powder structure the bars. Once baked, the hot base is immediately topped with marshmallows and chopped pecans, which gently melt and toast as they sit atop the warm cake. The final layer is a glossy chocolate frosting made from melted chocolate, oleo, eggs, vanilla, and confectioners’ sugar, spread over the cooled marshmallow and nut topping.
Serving Suggestions
Heavenly Hash Bars are best served at room temperature or slightly chilled. Cut them into small squares because they are quite rich. They pair wonderfully with a cup of coffee or cold milk. For an extra-special dessert, serve them with a scoop of vanilla ice cream.
Preparation Tips
- Line Your Pan: Use aluminum foil or parchment paper to line your baking pan for easy removal and clean-up.
- Watch the Baking Time: When removed from the oven, the base should be just set; do not overbake to ensure it stays moist under the toppings.
- Cooling Time: Allow the bars to cool completely before adding the chocolate topping to prevent it from sinking into the marshmallow layer.
- Cutting the Bars: Use a sharp knife and clean it between cuts to get clean, neat squares.
