Quick Toffee Chocolate Cake

A four-ingredient assembly cake that punches above its weight at 25 minutes. Store-bought pound cake gets sliced horizontally, layered with a fast chocolate-sour cream ganache, and crowned with crushed English toffee bars for crunch.

The frosting is the unsung star. Melted chocolate chips stirred with sour cream creates a velvety, slightly tangy ganache that’s far more interesting than canned frosting. The acid in the sour cream cuts the sweetness, the fat keeps it spreadable.

Three layers of toffee, between the layers, on top, and pressed against the sides if you’re feeling generous. The candy stays crunchy in the fridge for a day or two before softening.

Pro Tips

• Use a sharp serrated knife to slice the pound cake horizontally, a regular knife crushes the cake instead of cutting clean
• Let the chocolate cool slightly after melting before stirring in cold sour cream, the temperature shock can cause the chocolate to seize
• Crush the toffee in a zip-top bag with a rolling pin for control over the size of pieces
• Eat within 24 hours for best toffee crunch, the candy softens against the moisture-rich frosting after that

Variations

• Use Heath bar pieces or Skor bits if English toffee isn’t available
• Add a teaspoon of vanilla or a splash of bourbon to the ganache for added depth
• Drizzle warm caramel over the top before adding the toffee for extra indulgence
