How to Make Gran's Favorite Chocolate Cake

**Cake:** Preheat oven to 350°F (175°C). Grease and flour a 13x9 inch baking pan.
In a large bowl, whisk together 2 cups all-purpose flour, 2 cups granulated sugar, and 1 teaspoon salt.
In a separate saucepan, combine 1 cup (2 sticks) unsalted butter, ½ cup vegetable oil, 1 cup water, and ¾ cup unsweetened cocoa powder. Bring to a boil over medium heat, stirring constantly.
Pour the hot cocoa mixture into the dry ingredients and beat with an electric mixer until smooth.
Add 2 large eggs, 1 teaspoon baking soda, 1 cup buttermilk, and 1 teaspoon vanilla extract. Beat until well combined.
Pour batter into the prepared pan and bake for 25-30 minutes, or until a wooden skewer inserted into the center comes out clean.
Let the cake cool completely before frosting.
**Icing:** In a medium saucepan, combine ½ cup (1 stick) unsalted butter, 1 ½ cups granulated sugar, and ½ cup milk. Bring to a boil over medium heat, stirring constantly, and boil for 1 ½ minutes.
Remove from heat and stir in 1 cup mini marshmallows and ½ cup semi-sweet chocolate chips until melted and smooth.
Let the icing cool slightly, then stir in 1 teaspoon vanilla extract.
Spread the icing evenly over the cooled cake.
