Raisin Bar Sheet Cake: A Taste of Childhood

The scent of cinnamon and warm sugar still instantly transports me back to our bustling family kitchen. I remember standing on a wobbly stool, barely tall enough to reach the countertop, carefully measuring ingredients for this very cake. It was the first recipe I ever tackled on my own, a rite of passage marked not just by the delicious reward, but also by a minor kitchen catastrophe involving a metal bowl and boiling water. The burn was a quick lesson learned, and the resulting cake, slathered in sweet glaze, tasted like pure triumph. It’s a recipe that has stayed with me, a testament to the simple joys of baking and the enduring power of a mother’s recipe.

- 1 teaspoon baking powder

- 1 1/2 cups powdered sugar
- 1 1/2 tablespoons boiling water
- 1 teaspoon butter
- 1/2 teaspoon vanilla extract
- 1 teaspoon corn syrup

Equipment Needed

17 x 11 x 2 inch baking pan
Mixing bowls
Electric mixer or whisk
Measuring cups and spoons
Small saucepan or microwave-safe bowl

Instructions

Preheat your oven to 375°F (190°C). Generously grease a 17 x 11 x 2 inch baking pan to prevent sticking. This is crucial for easy removal of the cake after baking.
In a large mixing bowl, combine the eggs, brown sugar, raisins, all-purpose flour, shortening, cinnamon, baking powder, and baking soda.
Gradually pour in the boiling water while mixing continuously. Be careful as you add the water to avoid splashing. The batter will be quite thin – that’s perfectly normal.
Pour the batter into the prepared baking pan, spreading it evenly to ensure uniform baking.
Bake for 20 minutes. If you’re using a dark baking pan, start checking for doneness at 15 minutes to prevent over-browning. The cake is ready when a toothpick inserted into the center comes out clean or with a few moist crumbs attached.
Remove the cake from the oven and let it cool slightly in the pan. This is the perfect time to prepare the icing.
Make the Icing: In a medium-sized bowl, place the powdered sugar.
In a separate small bowl (or a microwave-safe bowl), combine the boiling water and butter. Heat until the butter is melted. You can do this in a microwave or over the stovetop.
Add the vanilla extract and corn syrup to the melted butter mixture. Stir to combine.
Pour the wet ingredients (butter, vanilla, corn syrup) into the bowl with the powdered sugar.
Beat with an electric mixer or whisk until the icing is smooth and creamy. If the icing is too thick, add a little more boiling water, a teaspoon at a time, until you reach the desired consistency. The icing should be thin enough to drizzle easily but not so thin that it runs right off the cake.
While the cake is still slightly warm, drizzle the icing evenly over the top. The warmth of the cake will help the icing to melt and create a lovely glaze.

Expert Tips & Tricks

Raisin Plumping: For extra plump and juicy raisins, soak them in hot water for about 15 minutes before adding them to the batter. Drain them well before using.
Spice it Up: Feel free to experiment with other spices like nutmeg, cloves, or allspice to add depth to the flavor profile. A quarter teaspoon of each can make a significant difference.
Shortening Substitute: While shortening contributes to a tender crumb, you can substitute it with melted coconut oil or unsalted butter for a slightly different flavor.
Preventing a Soggy Bottom: Make sure your oven rack is in the center position for even heat distribution. Also, avoid opening the oven door frequently during baking.
Icing Consistency: The key to a perfect glaze is the right consistency. Adjust the amount of boiling water in the icing to achieve a smooth, pourable texture.
Make Ahead: The cake can be baked a day in advance and stored, covered, at room temperature. Ice it just before serving for the best results.
Dark Pan Adjustment: Dark pans tend to bake faster and can sometimes cause the edges to burn. If using a dark pan, reduce the oven temperature by 25°F (15°C) and check for doneness a few minutes earlier.

Serving & Storage Suggestions

This Raisin Bar Sheet Cake is best served slightly warm or at room temperature. Cut it into squares or bars and enjoy it as a snack, dessert, or with a cup of coffee or tea.

Storage: Store leftover cake in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week.
Freezing: The cake freezes well. Wrap it tightly in plastic wrap and then in foil, or place it in a freezer-safe container. It can be frozen for up to 2 months. Thaw overnight in the refrigerator before serving.
Reheating: If desired, you can gently warm individual slices in the microwave for a few seconds before serving.

Variations & Substitutions

Nutty Delight: Add 1/2 cup of chopped walnuts or pecans to the batter for a nutty flavor and texture.
Citrus Zest: Grate the zest of one orange or lemon into the batter for a bright, citrusy twist.
Spice Cake: Substitute half of the all-purpose flour with whole wheat flour for a heartier cake. Add 1/4 teaspoon of ground cloves and 1/4 teaspoon of ground nutmeg to enhance the spice flavor.
Apple Raisin Cake: Add 1 cup of peeled and diced apples to the batter along with the raisins.
Chocolate Chip: Sprinkle 1/2 cup of mini chocolate chips over the top of the batter before baking for a touch of chocolate indulgence.
Vegan Variation: Substitute the eggs with flax eggs (1 tablespoon flaxseed meal mixed with 3 tablespoons water, let sit for 5 minutes). Use vegan shortening or coconut oil instead of regular shortening. Ensure the butter in the icing is also vegan.

FAQs (Frequently Asked Questions)

Q: Can I use a different type of sugar besides brown sugar?
A: While brown sugar contributes to the cake’s moistness and flavor, you can substitute it with granulated sugar, but the texture and taste will be slightly different.

Q: My cake came out dry. What could have gone wrong?
A: Overbaking is the most common cause of a dry cake. Make sure to check for doneness starting at 15 minutes and avoid over-baking. Using too much flour can also lead to a dry cake.

Q: Can I skip the corn syrup in the icing?
A: The corn syrup adds a bit of shine and smoothness to the icing, but you can omit it if you prefer. The icing might be slightly less glossy.

Q: How do I prevent the raisins from sinking to the bottom of the cake?
A: Toss the raisins with a tablespoon or two of flour before adding them to the batter. This will help them stay suspended throughout the cake.

Q: The icing is too runny. How can I thicken it?
A: Gradually add more powdered sugar, a tablespoon at a time, until you reach the desired consistency. Be sure to mix well after each addition.
