How I Make It

Step 1:

Start by preheating your oven to 350°F and greasing a 9-inch round cake pan. In a large bowl, cream together the butter, granulated sugar, and brown sugar until fluffy and light. This step is key—don’t rush it, the texture here sets the stage for a soft cake.

Step 2:

Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract. In a separate bowl, whisk the flour, cocoa powder, baking powder, and salt. Gradually add the dry ingredients to the creamed mix, alternating with the milk, starting and ending with the dry ingredients.

Step 3:

Pour the batter into your prepared pan and bake for about 35-40 minutes, or until a toothpick inserted comes out with just a few moist crumbs. Let the cake cool completely in the pan on a wire rack.

Step 4:

While the cake cools, make the caramel topping. In a heavy saucepan, heat the granulated sugar over medium heat, swirling occasionally but not stirring, until it melts into a deep amber syrup. Add the butter pieces carefully—it will bubble up—and stir to combine.

Step 5:

Slowly whisk in the warm heavy cream until smooth, then stir in the salt. Remove from heat and set aside to cool slightly.

Step 6:

Next, make the toffee crunch by combining brown sugar, butter, and corn syrup in a saucepan over medium heat. Cook until the mixture turns a caramel color and reaches the hard crack stage (~300°F on a candy thermometer). Quickly stir in the nuts and spread the toffee onto a parchment-lined baking sheet. Sprinkle the mini chocolate chips over the hot toffee; once melted, spread evenly to coat. Let cool completely, then break into crunchy shards.

Step 7:

To assemble, drizzle the caramel over the cooled cake and sprinkle generously with the toffee crunch shards. If you want an extra glossy finish, warm the caramel slightly before drizzling.

Variations & Tips

• Swap nuts for chopped pretzels for a salty crunch.
• Use store-bought caramel sauce for a shortcut but watch for sugar content.
• Swap cocoa powder for espresso powder to deepen the chocolate flavor.
• To keep the toffee shards crisp, store separately until just before serving.
• If your caramel hardens too fast when making, gently warm the pan over low heat and stir.

How I Like to Serve It

This cake is a dream for holiday parties or any gathering where you want to impress without stress. It pairs beautifully with a scoop of vanilla ice cream, and a cup of strong coffee balances those rich layers perfectly. Bonus points if you serve it with friends who appreciate the chocolate-caramel-toffee combo as much as I do!

Notes

• Store leftover cake tightly covered at room temperature for up to 3 days.
• Reheat slightly in the microwave (10 seconds) to revive softness before serving.
