An overhead shot of a golden-brown bundt cake with deep ridges catching the warm afternoon light streaming through kitchen windows. The cake's glossy bourbon-orange glaze drips tantalizingly down the sides, pooling on a vintage cake stand. Close-up details reveal specks of toasted black walnuts and orange zest scattered throughout the moist crumb. A cross-section slice on a small plate shows the cake's tender interior, while garnishes of candied orange peel and whole black walnuts create visual interest. A cut crystal tumbler with an old fashioned cocktail sits blurred in the background, connecting the cake to its cocktail inspiration.

Directions

<ol class="no-list-style"> <li class="MethodStepper"> <h4 class="step-title">Step 1</h4> Preheat your oven to 170°C. Spread the chopped black walnuts on a baking sheet and toast for 8-10 minutes until fragrant and slightly darkened, stirring halfway through. This toasting step is crucial as it intensifies the nutty flavor that defines this recipe. Allow to cool, then place in a bowl and pour 30ml of bourbon over them. Let soak for at least 30 minutes, stirring occasionally. </li> <li class="MethodStepper"> <h4 class="step-title">Step 2</h4> Prepare your bundt pan by thoroughly greasing every crevice with butter, then dusting with flour. Tap out any excess flour. A well-prepared pan ensures your cake releases cleanly after baking. </li> <li class="MethodStepper"> <h4 class="step-title">Step 3</h4> In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon. This pre-mixing ensures even distribution of leavening agents throughout your cake, preventing uneven rise. </li> <li class="MethodStepper"> <h4 class="step-title">Step 4</h4> In the bowl of your stand mixer fitted with the paddle attachment, cream the softened butter for 2 minutes until smooth. Gradually add both sugars and beat on medium-high speed for 4-5 minutes until pale and fluffy. This extended creaming process incorporates air into the butter-sugar mixture, creating the foundation for a tender crumb. </li> <li class="MethodStepper"> <h4 class="step-title">Step 5</h4> Add eggs one at a time, beating well after each addition. Scrape down the sides of the bowl as needed. Add the vanilla extract, orange zest, and 2 teaspoons of bitters, mixing until well combined. The slow addition of eggs maintains the emulsion and prevents curdling. </li> <li class="MethodStepper"> <h4 class="step-title">Step 6</h4> Add the flour mixture in three parts, alternating with the buttermilk in two parts, beginning and ending with the dry ingredients. Mix on low speed just until combined after each addition. This alternating method prevents gluten development, keeping your cake tender while properly hydrating the flour. </li> <li class="MethodStepper"> <h4 class="step-title">Step 7</h4> Fold in the bourbon-soaked walnuts (including any remaining bourbon liquid) using a rubber spatula. Pour the batter into the prepared bundt pan, smoothing the top with your spatula. Tap the pan firmly on the counter a few times to release any trapped air bubbles. </li> <li class="MethodStepper"> <h4 class="step-title">Step 8</h4> Bake at 170°C for 50-55 minutes, or until a wooden skewer inserted in the center comes out clean or with a few moist crumbs. The cake will be golden brown and will have started to pull away slightly from the sides of the pan. </li> <li class="MethodStepper"> <h4 class="step-title">Step 9</h4> Allow the cake to cool in the pan for exactly 15 minutes - this timing is crucial. If removed too soon, it may fall apart; too late, and it might stick. Invert onto a wire rack and allow to cool completely before glazing. </li> <li class="MethodStepper"> <h4 class="step-title">Step 10</h4> For the glaze, whisk together powdered sugar, remaining 30ml bourbon, orange juice, bitters, and salt until smooth. Adjust consistency if needed - it should be thick enough to coat the back of a spoon but still pourable. The alcohol will not be cooked out in this glaze, adding an authentic cocktail flavor. </li> <li class="MethodStepper"> <h4 class="step-title">Step 11</h4> Place the cooled cake on a serving plate with parchment paper tucked underneath the edges to catch drips. Pour the glaze evenly over the top, allowing it to drip dramatically down the sides. Garnish with additional toasted black walnuts and orange zest if desired. Let the glaze set for about 20 minutes before serving. </li> </ol>

Chef’s Notes

A few helpful details for making this recipe.

Can I substitute regular walnuts if I can't find black walnuts?

Yes, you can substitute regular walnuts, though black walnuts provide a more distinctive, intense flavour that perfectly complements the bourbon. If using regular walnuts, consider adding 1/4 teaspoon of walnut extract to the batter to enhance the nutty profile that makes this cake special.

How long does the bourbon flavour last in this cake?

The bourbon flavour remains prominent for about 3-4 days after baking. The cake itself stays moist for up to 5 days when stored in an airtight container at room temperature. The alcohol in the glaze never cooks off, maintaining that authentic cocktail essence throughout the cake's shelf life.

What's the best bourbon to use in a walnut cake with Old Fashioned flavours?

Choose a mid-range bourbon with caramel and vanilla notes like Buffalo Trace or Maker's Mark. Avoid overly smoky or peaty whiskies. The bourbon should complement the walnuts and orange without overpowering - budget bourbons can work well as the cake's other flavours will balance any harshness.
