Ingredients:
- 1 cup (2 sticks) unsalted butter, softened to room temperature
- 1¼ cups granulated sugar
- 1 teaspoon pure vanilla extract
- 4 medium eggs, at room temperature
- 1¾ cups self-raising flour
- ¼ cup unsweetened cocoa powder
- 3 tablespoons whole milk
- 1½ cups powdered sugar, sifted
- 1 tablespoon unsweetened cocoa powder
- 2 tablespoons milk
- Chocolate sprinkles for decorating
Baking the Old School Chocolate Traybake Cake
Preparing the Cake Batter
- Cream the Butter and Sugar: In a large mixing bowl, cream together the softened unsalted butter and granulated sugar. This is a crucial first step for achieving a light and airy cake texture. Use an electric mixer on medium speed, or a sturdy whisk and some elbow grease, and beat them together until the mixture is pnon-alcoholic ale and fluffy. This process, known as creaming, incorporates air into the butter and sugar, which will expand during baking and contribute to the cake’s rise. Scrape down the sides of the bowl occasionally to ensure all the butter and sugar are well combined.
- Incorporate Eggs and Vanilla: Add the eggs one at a time to the creamed butter and sugar mixture, beating well after each addition. It’s important that the eggs are at room temperature, as this helps them emulsify better with the butter and sugar, preventing the mixture from looking curdled. If your eggs are cold, you can quickly warm them by placing them in a bowl of warm water for a few minutes. Once all the eggs are incorporated, stir in the pure vanilla extract. The vanilla adds a warm, comforting aroma and flavor that complements the rich chocolate perfectly.
- Add Dry Ingredients and Milk: In a separate bowl, whisk together the self-raising flour and ¼ cup of unsweetened cocoa powder. Sifting these dry ingredients together ensures they are evenly distributed and free from any lumps. Gradually add the dry ingredients to the wet ingredients in three additions, alternating with the 3 tablespoons of whole milk. Begin extract and end with the dry ingredients. Mix on low speed until just combined after each addition. Be careful not to overmix at this stage, as overmixing can develop the gluten in the flour too much, resulting in a tough cake. A few streaks of flour are okay, as they will disappear during the final mixing. Ensure the batter is smooth but don’t beat it excessively.
Baking and Cooling
- Prepare the Tray and Bake: Preheat your oven to 350°F (175°C). Grease and line a standard 9×13 inch (or similar size) baking tray with parchment paper, leaving an overhang on the sides to make it easy to lift the cake out later. Pour the cake batter evenly into the prepared tray, smoothing the top with a spatula. Bake for 25-30 minutes, or until a wooden skewer or toothpick inserted into the center of the cake comes out clean. The aroma of warm chocolate will fill your kitchen, a sure sign that your Old School Chocolate Traybake Cake is nearing perfection.
- Cool the Cake: Once baked, remove the tray from the oven and let the cake cool in the tray for about 10-15 minutes. This allows the cake to firm up slightly before you attempt to remove it. After this initial cooling period, use the parchment paper overhang to carefully lift the cake out of the tray and place it on a wire rack to cool completely. It is essential that the cake is entirely cool before you attempt to frost it, otherwise, the frosting will melt and slide off.
Making the Chocolate Glaze and Decorating
- Prepare the Chocolate Glaze: While the cake is cooling, prepare the rich chocolate glaze. In a medium bowl, combine the sifted powdered sugar and the remaining 1 tablespoon of unsweetened cocoa powder. Gradually add the 2 tablespoons of milk, mixing until you achieve a smooth, pourable consistency. If the glaze is too thick, add a tiny bit more milk, a teaspoon at a time, until it reaches your desired texture. Conversely, if it’s too thin, add a little more sifted powdered sugar. This glaze should be thick enough to coat the cake but still spreadable.
- Glaze and Decorate: Once the cake is completely cool, pour the prepared chocolate glaze over the top. Use an offset spatula or the back of a spoon to spread the glaze evenly across the surface of the cake, letting it drip slightly down the sides for a rustic, inviting look. Immediately after glazing, sprinkle generously with chocolate sprinkles. The sprinkles add a delightful textural contrast and a classic finishing touch that makes this Old School Chocolate Traybake Cake truly special. Let the glaze set for at least 15-20 minutes before slicing and serving.

Frequently Asked Questions:
Can I make this Old School Chocolate Traybake Cake ahead of time?

What kind of chocolate should I use for the Old School Chocolate Traybake Cake?
