Warm your oven to a cozy 180°C, preparing it to transform simple ingredients into chocolate perfection. Line your cherished 8x10 tin with parchment, creating a clean workspace.

Growing up, my mother would always test chocolate cakes by their aroma - when the kitchen filled with that deep, rich scent, she knew it was nearly done. This wisdom has guided my baking ever since, making each chocolate creation a sensory journey.

Serving Your Chocolate Creation

Transform this classic cake into an elevated dessert experience by warming individual slices and serving with vanilla bean ice cream. Pour warm custard over the top for a traditional school dinner treat. For afternoon tea, pair squares with strong coffee or milk for children. Add fresh raspberries on the side for a fruity contrast that cuts through the rich chocolate.

Sweet Variations

Enhance the chocolate experience by adding a layer of chocolate ganache beneath the icing. Incorporate chocolate chips into the batter for extra indulgence. Swap vanilla extract for orange extract to create a chocolate-orange sensation. Add a pinch of espresso powder to deepen the chocolate flavor without tasting like coffee. Consider a cream cheese frosting for a tangy contrast.

Keeping Fresh Memories

Store your chocolate traybake in an airtight container at room temperature, where it stays perfectly moist for five days. For longer storage, wrap individual slices in parchment paper and freeze for up to three months. When ready to enjoy, thaw at room temperature for about an hour. A quick five-second microwave creates that fresh-baked warmth.

Temperature Matters

Achieving the perfect chocolate cake requires attention to ingredient temperatures. Cold eggs can cause the batter to curdle, while overly soft butter might make the cake greasy. Room temperature ingredients create the ideal environment for baking success.

Cocoa Knowledge

Understanding different types of cocoa powder affects your final result. Natural cocoa provides bright chocolate notes, while Dutch-processed offers deeper, richer flavor. Both work beautifully in this recipe, creating slightly different but equally delicious results.

Yield: 12 Servings

Dietary: Vegetarian

Ingredients

→ For the Cake

01 1 cup (2 sticks) unsalted butter, softened to room temperature
02 1¼ cups granulated sugar
03 1 teaspoon pure vanilla extract
04 4 medium eggs, at room temperature
05 1¾ cups self-raising flour
06 ¼ cup unsweetened cocoa powder
07 3 tablespoons whole milk

→ For the Chocolate Glaze

08 1½ cups powdered sugar, sifted
09 1 tablespoon unsweetened cocoa powder
10 2 tablespoons milk
11 Chocolate sprinkles for decorating

Instructions

Step 01

Start by preheating your oven to 350°F. Take a moment to line your 8x10-inch baking pan with parchment paper, making sure to leave some overhang for easy removal later.

Step 02

In a large bowl, beat your softened butter and sugar together until light and fluffy - this usually takes about 3-4 minutes with an electric mixer. Add the vanilla, then gradually beat in the eggs one at a time. Finally, gently fold in the flour, cocoa powder, and milk until you have a smooth, chocolatey batter.

Step 03

Spread the batter evenly in your prepared pan. Pop it in the oven for 25-30 minutes, or until a toothpick poked in the center comes out clean. Let it cool in the pan for 10 minutes before transferring to a wire rack.

Step 04

Once the cake is completely cool, whisk together the glaze ingredients until smooth. Pour over your cake and spread evenly, then shower with chocolate sprinkles. Let the glaze set before cutting into squares.

Notes

  1. This cake keeps well in an airtight container for up to 5 days
  2. You can adjust the glaze thickness by adding more milk or powdered sugar to reach your desired consistency
