Step-by-Step Instructions

Prepare the Chocolate Cake
Preheat oven to 350°F (175°C). Grease and flour two 9-inch round pans. In a large bowl, whisk together flour, sugar, cocoa, baking powder, baking soda, and salt. Add eggs, milk, oil, and vanilla, mixing until smooth. Gradually stir in boiling water; batter will be thin. Divide evenly between pans and bake 30–35 minutes, until a toothpick comes out clean. Cool 10 minutes in pans, then transfer to wire racks.

Prepare the Caramel Frosting
Beat butter until creamy. Gradually add powdered sugar, caramel sauce, vanilla, and a pinch of salt. Beat until light, fluffy, and spreadable.

Assemble the Cake
Place one cake layer on a serving plate and spread a generous layer of frosting. Top with the second layer, then frost the top and sides of the cake. Sprinkle toffee bits and optional nuts over the top, pressing lightly to adhere.

Garnish and Serve
Drizzle extra caramel sauce over the top and add chocolate shavings or curls for an elegant finish. Slice and serve immediately.

Recipe Notes & Tips

Thin Batter Is Normal – The boiling water makes the cake incredibly moist; don’t worry about consistency.
Even Frosting – Chill cake layers slightly if needed to prevent frosting from sliding.
Prevent Sogginess – Cool cakes completely before frosting.
Optional Nuts – Toast for extra flavor and crunch.
Decorative Touches – Chocolate curls can be made by shaving a chocolate bar with a vegetable peeler.
