0.25 teaspoon fine salt (for Irish Whiskey Salted Caramel)
Instructions
Set oven to 165°C. Grease a 10-cup bundt pan generously with nonstick baking spray.
In a large bowl, whisk granulated sugar, brown sugar, all-purpose flour, cocoa powder, espresso powder, baking soda, baking powder, and salt until thoroughly combined. Break up lumps if necessary.
In a separate bowl, whisk eggs, sour cream, Guinness, whole milk, vegetable oil, and vanilla extract until smooth and homogeneous.
Pour the wet mixture into the dry ingredients and stir until just combined. Avoid overmixing to maintain moisture.
Transfer the batter to the prepared bundt pan. Bake for 50 minutes or until a toothpick inserted in the center emerges clean.
Allow the cake to rest in the pan for 15 minutes. Invert carefully onto a wire rack and cool completely before frosting.
In a large bowl, beat unsalted butter on medium speed until smooth. Gradually add sifted confectioners’ sugar, beating well after each addition. Blend in Baileys, milk, vanilla, and salt until fluffy. Drizzle in melted white chocolate and beat another 1–2 minutes until creamy.
In a saucepan, heat granulated sugar and water over medium, stirring until sugar dissolves. Increase heat to medium-high and cook without stirring until the syrup turns an amber hue. Carefully whisk in cold cubed butter—mixture will bubble. Gradually pour in heavy cream while whisking. Stir in Irish whiskey, vanilla, and salt. Remove from heat and cool slightly before use.
Spread or pipe Baileys buttercream evenly over the completely cooled bundt cake. Generously drizzle Irish whiskey salted caramel over the top to finish.
Slice and serve for an indulgent dessert.
Notes
Ensure all ingredients are at room temperature for best results.
Do not overmix the batter to keep the cake moist.
Adjust the sweetness of the buttercream as per your preference.
Irish whiskey salted caramel is optional but adds a great flavor.
