Irish Whiskey Cake
Fruit soaked in Irish whiskey and orange juice, then simmered with butter and sugar: that is the heart of Vanessa Greenwood’s Irish whiskey cake. Her mixed dried fruit and cherries belong to a boiled fruit cake, but the name opens onto quite different bakes. Margaret M. Johnson’s version is a lighter, spiced raisin cake with whiskey icing. Darina Allen’s rich Christmas cake divides its whiskey between soaking the fruit and pouring over the baked cake, with another addition in the almond paste.[5][6][9]
The best starting point is a complete published recipe whose fruit, spice and finish appeal to you. Follow its quantities and sequence together, rather than borrowing a little from several versions.
What kind of Irish whiskey cake?
Greenwood’s cake begins with a saucepan. She describes it as “a traditional boiled fruit cake”, a Northern Ireland bake from her stepmother Roberta’s family. Simmering the soaked fruit with butter and sugar is an essential stage before completing the batter, not simply a way to warm the ingredients.[5]
Margaret M. Johnson’s Irish Whiskey Cake puts spice to the fore. Published in the Irish Echo in 2018, it contains sultanas, walnuts, cloves, nutmeg and allspice. Johnson describes it as tasting more like a spicy raisin cake than a fruitcake. Whiskey appears in both the cake and its icing, making the finish part of the recipe’s character.[9]
Allen’s Christmas cake is rich fruit cake finished with almond paste. Her recipe uses 70 ml Irish whiskey, divided between the fruit and the baked cake, with a further two tablespoons in the almond paste. These are separate additions at different stages, not one quantity poured into the batter.[6]
Choose by the style of cake and the finish you want, without expecting one version to define the name.
A closer look at Vanessa Greenwood’s recipe
Greenwood’s ingredient list gives a clear picture of her boiled fruit cake: mixed fruit and cherries, mixed spice, and equal measures of whiskey and orange juice. These are her published quantities, not a separately developed or site-tested recipe.[5]
| Part of the cake | Ingredients in Greenwood’s recipe |
|---|---|
| Fruit and spice | 450 g mixed fruit, 50 g glacé cherries, 1 teaspoon mixed spice |
| Soaking liquids | 100 ml Irish whiskey, 100 ml orange juice |
| Butter and sugar | 100 g butter, 175 g golden caster sugar |
| Remaining batter | 2 eggs, 100 g self-raising flour, 1 teaspoon bread soda |
All quantities come from Greenwood’s recipe.[5] “Bread soda” is the wording in her published ingredient list. Use Greenwood’s complete published recipe for the preparation and baking instructions, rather than treating this ingredient summary as a substitute.
An eight-hour rest sets the pace of this recipe. Before it, Greenwood simmers the soaked fruit with the butter and sugar for 10 minutes. After it, the stated bake begins with 10 minutes at 190°C fan, followed by 50 minutes at 170°C. Plan around that pause: this is not a cake to start immediately before you want to bake.[5]
Fruit preparation, simmering, resting and baking are distinct stages, with the whiskey incorporated into that sequence. The saucepan stage and the long rest are as much a part of Greenwood’s method as the time in the oven.
For the wider principles of adding spirits to food, see cooking with whisky. Here, the useful detail lies in how each published cake uses its whiskey, rather than in a single method that could be applied to any cake.
Where the whiskey goes
The whiskey’s destination matters as much as its quantity. It may go into the fruit mixture, be poured over the baked cake or appear in a separate finish.[5][6][9]
| Published recipe | Before baking | After baking or in the finish |
|---|---|---|
| Vanessa Greenwood | 100 ml Irish whiskey with the fruit mixture | A teaspoon of whiskey each week during her stated storage period |
| Darina Allen | Half of 70 ml Irish whiskey macerates the fruit for one hour | Remaining half poured over the cake; two tablespoons in almond paste |
| Margaret M. Johnson | A quarter cup Irish whiskey in the cake recipe | One tablespoon Irish whiskey in the icing |
These are the authors’ published methods, not equivalent substitutions. A quantity assigned to one stage is not necessarily the total for the cake.[5][6][9]
Allen’s recipe has three distinct uses: the fruit soak, the addition after baking and the almond paste. Johnson’s whiskey icing is likewise a separate component, not merely a decorative change. Choosing either recipe means choosing its finish as well as its batter.[6][9]
Feeding and storing the cake
Greenwood describes keeping her cake for one or two weeks and “feeding it with a teaspoon of whiskey each week”. That is her recipe’s stated practice, not a universal storage instruction for every cake containing whiskey.[5]
The comparison above separates feeding from pouring and icing. Greenwood’s weekly teaspoon, Allen’s post-bake addition and Johnson’s whiskey icing belong to their respective recipes; they are not three steps that every Irish whiskey cake needs.[5][6][9]
When setting out ingredients, reserve the whiskey intended for the finish. It remains part of the recipe even though it does not enter the oven with the batter.
Does the alcohol bake out?
Baking reduces alcohol, but does not reliably remove it. The USDA’s published retention table gives the following figures for alcohol stirred into a mixture and then baked or simmered; these are general alcohol data, not measurements of the cakes described here.[12]
| Baking or simmering time | Alcohol retained in the USDA table |
|---|---|
| 15 minutes | 40% |
| 30 minutes | 35% |
| 1 hour | 25% |
| 2 hours | 10% |
| 2.5 hours | 5% |
These percentages describe the proportion of the original alcohol retained, not the alcoholic strength of the finished cake. They cannot establish the alcohol content of a slice of Greenwood’s, Allen’s or Johnson’s cake.[12]
The USDA also lists 70% retention for alcohol added without heat and stored overnight. That figure is not a measurement of a fed fruit cake, but it does show why an overnight rest should not be described as removing an unheated alcohol addition. Whiskey added after baking or included in icing should not be assumed to disappear.[12]
Describe these cakes plainly as containing alcohol. Neither a long bake nor a later storage period justifies calling a whiskey cake alcohol free on the evidence available here.[12]
Whiskey in an earlier cake record
Sixteen yolks, eight whites and “one naggin of whiskey”: a manuscript lemon cake takes the story back to approximately 1830. Held by the National Library of Ireland as MS 42,267, the manuscript contains a “Receipt to make a lemon cake”, an earlier documented example of whiskey in cake rather than one of the fruit cakes discussed above.[4] Source: National Library of Ireland.
Alongside those eggs and whiskey, the recipe calls for a pound of lump sugar, ten ounces of flour and half a naggin of candied lemon syrup, with a two-hour bake. Source: National Library of Ireland.
Claim and verdict: Documented. The manuscript records whiskey as an ingredient in this particular lemon cake around 1830. Its place of composition within Ireland is not established, and the record does not establish a shared origin for later whiskey cakes. The lemon syrup and large quantity of eggs make it a different proposition from Greenwood’s mixed-fruit version.[4][5]
MS 42,267, approximately 1830, is the earliest known source for this example. The manuscript reference, approximate date, title, ingredients and baking time are reported in the National Library of Ireland’s “Cooking the Books”.

Whiskey cake and tea brack
Tea brack and traditional barmbrack use different methods. Martin Dwyer describes traditional barmbrack as made with yeast like bread, while calling tea brack “a more homely version”. His published tea brack, drawn from a Theodora FitzGibbon recipe, soaks fruit overnight in one cup of whiskey and two cups of tea.[10]
That overnight soak offers another documented meeting of whiskey and dried fruit, but it is distinct from Greenwood’s simmered fruit preparation. Keep both the names and the methods in mind when choosing a recipe: tea brack’s tea-and-whiskey soak is not the saucepan stage of a boiled fruit cake.[5][10]
For a wider view of accompaniments, see whisky and food pairing. Let the chosen cake lead the pairing, whether its recipe centres on mixed fruit, spice or a whiskey-containing finish.
Whiskey cake is one place to begin exploring spirits in desserts. The next recipe might take you towards whisky, pecans or chocolate.
Where to go next
- Cranachan: explore another dessert using whisky.
- Bourbon Pecan Pie: compare a different spirit-led baking recipe.
- Whisky and Chocolate: Pairings That Work and Why: consider chocolate alongside whisky.
