Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 20 minutes
• Total Time: 35 minutes
• Servings: 24
• Yield: 1 sheet cake
• Dietary Type: Not specified

Ingredients

• 2 cups flour
• 2 cups sugar
• 1/2 cup margarine
• 4 tablespoons cocoa
• 1 cup cold water
• 1/2 cup buttermilk
• 1 teaspoon vanilla
• 1/2 teaspoon baking powder
• 1 teaspoon baking soda
• 2 eggs
• 1 teaspoon cinnamon
• 1/4 teaspoon salt

Equipment Needed

• Large mixing bowl
• Saucepan
• Greased jelly roll pan (deep cookie sheet)
• Measuring cups and spoons
• Mixer (hand or stand mixer)

Instructions

1. Preheat your oven to 400 degrees Fahrenheit. Ensure your jelly roll pan (a deep cookie sheet) is well-greased. This will prevent the cake from sticking and make it easy to remove after baking.
2. In a large mixing bowl, combine the flour and sugar. Set this mixture aside.
3. In a saucepan, combine the margarine, cocoa, and cold water. Bring this mixture to a boil over medium heat, stirring constantly to prevent scorching. Once boiling, remove from heat immediately.
4. Pour the hot margarine-cocoa mixture over the flour-sugar mixture in the large bowl. Mix well to combine, ensuring no dry flour remains.
5. Add the remaining ingredients to the bowl: the buttermilk, vanilla, baking powder, baking soda, eggs, cinnamon, and salt.
6. Mix all ingredients together thoroughly until a smooth batter forms. Be careful not to overmix, as this can result in a tough cake. A few small lumps are okay.
7. Pour the batter into the prepared, greased jelly roll pan, spreading it evenly across the surface.
8. Bake in the preheated oven for 20 minutes. To check for doneness, insert a toothpick into the center of the cake. If it comes out clean or with just a few moist crumbs attached, the cake is done. If the toothpick comes out with wet batter, bake for a few more minutes and check again.
9. Remove the cake from the oven and let it cool in the pan before frosting.

Expert Tips & Tricks

• Buttermilk Substitute: If you don’t have buttermilk on hand, you can make a quick substitute by adding 1 1/2 teaspoons of lemon juice or white vinegar to 1/2 cup of regular milk. Let it sit for 5 minutes before using.
• Room Temperature Ingredients: While the recipe doesn’t explicitly call for it, using room temperature eggs can help the batter emulsify better, leading to a slightly softer and more tender cake.
• Pan Prep is Key: Thoroughly greasing the jelly roll pan is crucial. You can even dust it with cocoa powder after greasing to prevent any white residue from the flour.
• Don’t Overbake: This cake is best when it’s moist. Overbaking will result in a dry cake, so keep a close eye on it during the last few minutes of baking.
• Even Baking: To ensure even baking, rotate the cake halfway through the baking time. This helps prevent hot spots in your oven from causing uneven browning.

Serving & Storage Suggestions

Fran’s Chocolate Sheet Cake is best served slightly cooled, allowing the frosting to set but still be soft and creamy. Cut into squares and serve as is, or with a scoop of vanilla ice cream or a dollop of whipped cream for an extra indulgent treat.

• Storage: Store leftover cake in an airtight container at room temperature for up to 3 days.
• Refrigeration: For longer storage, refrigerate the cake in an airtight container for up to a week.
• Freezing: You can also freeze the cake for up to 2-3 months. Wrap the cake tightly in plastic wrap, then in foil, before freezing. Thaw overnight in the refrigerator before serving.
• Reheating: If desired, individual slices can be gently warmed in the microwave for a few seconds before serving.
