How to Make Irish Whiskey Cake
Step 1. Begin by creaming together the 2 ½ sticks of unsalted butter and 1 ¼ cups of superfine sugar in a large mixing bowl. Use an electric mixer on medium speed or a whisk until the mixture is light and fluffy. This process incorporates air, which helps give your cake a nice rise.
Step 2. Next, add the 6 beaten eggs into the butter-sugar mixture gradually, ensuring they are fully integrated after each addition. The eggs contribute moisture to the batter and help achieve a successful structure, so take your time until everything is well combined and fluffy.
Step 3. Now, sift in the 2 cups of self-rising flour and the ⅛ teaspoon of salt into the bowl. Carefully fold the dry ingredients into the wet mixture using a spatula or spoon. You want to combine them without overmixing, which can lead to a dense texture. The batter should look smooth and slightly thick.
Step 4. Gently stir in the 2 tablespoons of Irish whiskey, ensuring it’s evenly distributed throughout the batter. The whiskey adds a delightful complexity to the flavor of the cake, so keep an eye on your consistency, looking for a well-blended, cohesive batter.
Step 5. Once the batter is ready, pour it into a prepared cake pan, smoothing the top with a spatula. Ensure the entire surface is even, which will help the cake bake uniformly without doming in the center.
Step 6. Bake the cake in the oven until it turns a golden brown and springs back when lightly pressed. Watch for a slight crust forming on the edges, as this indicates the cake is nearly done. To test, insert a toothpick into the center; it should come out clean or with just a few crumbs attached.
Step 7. While the cake is baking, prepare the filling by creaming together the 1 ¼ sticks of softened unsalted butter and 4 ½ cups of powdered sugar in another bowl. The mixture should be smooth and spreadable, providing a rich sweetness to complement the whiskey attributes.
Step 8. Mix in the 1 tablespoon of whiskey and the 1 tablespoon of milk to the filling, blending until creamy and homogeneous. This infusion adds moisture and enhances the flavor profile, creating a luxurious filling for your cake.
Step 9. After the cake has cooled, slice it in half horizontally to create two layers. Spread the whiskey filling generously on the bottom layer, ensuring even coverage to maintain a moist and flavorful bite.
Step 10. Place the top layer of the cake back on, gently pressing down to ensure it bonds with the filling. This layering not only adds depth but also ensures every slice has a balance of cake and rich filling.
Step 11. To make the glaze, combine the ¼ stick of butter, ½ cup of heavy whipping cream, ¼ cup of white sugar, 2 tablespoons of brown sugar, and 2 tablespoons of Irish whiskey in a small saucepan. Cook over medium heat, stirring until the sugars dissolve completely and the mixture is well combined and glossy.
Step 12. Pour the glaze over the assembled cake, allowing it to drip down the sides for a beautiful finish. This glaze adds a lovely sheen and further enhances the cake’s moist texture and whiskey flavor.

Pro Tips for Best Results
- Ensure your butter is at room temperature for smoother mixing and better incorporation.
- Use superfine sugar to create an airy texture in the cake.
- Be gentle when mixing in the flour to prevent a dense cake.
- Allow the cake to cool completely before icing to keep the glaze intact.
- Keep the cake covered or in an airtight container to maintain its moisture.
Common Mistakes to Avoid
- Using Cold Butter: This can cause uneven mixing and a dense texture. Always use room-temperature butter for the best results.
- Overmixing the Batter: This can develop the gluten too much, resulting in a tough cake. Mix just until combined for a tender crumb.
- Not Sifting Flour: Sifting helps eliminate lumps and aerate the flour, which is crucial for a light cake. Always sift your dry ingredients.
- Skipping the Cooling Time: Icing a warm cake can cause the glaze to run off. Allow the cake to cool completely before adding any frosting.
- Not Measuring Ingredients Precisely: Improper measurements can throw off the balance of flavors and textures. Use the correct tools to measure accurately.
- Ignoring Flavor Balance: Adjusting the whiskey too much can overpower the cake. Stick to the recipe for a harmonious flavor.
Variations & Substitutions
For a twist, add a dash of vanilla extract to the batter. You can also experiment with different types of whiskey for varied flavor profiles. If you prefer a fruitier option, consider layering the cake with fresh berries along with the filling, which can add a refreshing contrast and moisture.
Storage & Reheating
Store the cake at room temperature in an airtight container for up to three days. If you’re keeping it longer, refrigerate it, which can extend its freshness. The cake can also be frozen for up to three months—wrap it tightly in plastic wrap followed by aluminum foil. Defrost at room temperature or gently in the refrigerator before serving for the best texture.
