Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 180°C. Grease and line a 23cm round cake tin with parchment paper. This proper preparation ensures your cake will release easily after baking.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>In a large bowl, cream together the softened butter and caster sugar until pale and fluffy, about 5 minutes. This extended creaming process creates air pockets that give your cake its light texture.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Add the eggs one at a time, beating thoroughly after each addition. If the mixture begins to curdle, add a tablespoon of the measured flour to stabilize the emulsion.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Gently fold in the flour and baking powder using a large metal spoon or silicone spatula. Incorporate with a light hand to maintain the air you've created during creaming.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Divide the batter equally into three bowls. To the first, add the orange zest and Campari; to the second, add the sweet vermouth; to the third, add the prosecco. Gently fold each addition into its respective portion of batter.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Layer the batters in the cake tin: Campari mixture first, then vermouth, finally prosecco on top. Don't worry about perfect layers – the slightly marbled effect will be reminiscent of the cocktail's blended appearance.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Bake for 45-50 minutes, until a skewer inserted into the center comes out clean. The cake should be golden on top and spring back when lightly touched.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>While the cake is baking, prepare the syrup. Combine all syrup ingredients in a small saucepan and heat gently until the sugar dissolves completely. Bring to a simmer, then remove from heat.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>When the cake comes out of the oven, leave it in the tin and immediately poke all over with a skewer. Gradually pour the warm syrup over the hot cake, allowing it to absorb between additions. The warm cake will soak up the syrup more effectively, distributing the cocktail flavors throughout.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Allow the cake to cool completely in the tin before carefully removing to a wire rack. This patience ensures the syrup-soaked cake doesn't break apart.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>For the glaze, whisk together the powdered sugar and enough Campari to achieve a thick but pourable consistency. The vibrant red will be visually reminiscent of the classic cocktail.</li><li class="MethodStepper"><h4 class="step-title">Step 12</h4>Pour the glaze over the cooled cake, allowing it to drip attractively down the sides. Decorate with orange slices to reference the traditional garnish of the Negroni Sbagliato cocktail.</li><li class="MethodStepper"><h4 class="step-title">Step 13</h4>Let the glaze set for about 30 minutes before slicing. The cake will keep for up to 5 days in an airtight container, with the flavors developing and melding beautifully over time – much like a good cocktail!</li></ol>
