Black walnut extract substitutes
Black walnut extract substitutes — 6 options, ranked, with the exact amount
Use Black walnuts, toasted and finely ground
Per 1 tsp black walnut extract
1/3 cup finely chopped or ground black walnuts
Use 1 to 1 ½ teaspoons of ordinary walnut extract per teaspoon of black walnut extract, plus 1 teaspoon of dark molasses or ¼ teaspoon of instant coffee to bring back the earthy bitterness that plain walnut lacks. Ground toasted black walnuts are the real answer, and ¼ teaspoon of almond extract will at least make a cake read as a nut cake.

Black walnuts, toasted and finely ground
enhanced taste, different texture
The nut itself, which is what the extract is an imitation of.
- Best for
- black walnut cake, black walnut fudge, hummingbird cake, brownies, ice cream
If you can get the nuts, use the nuts. Nothing else carries that winey, faintly petrol-and-earth quality, and unlike the extract they also add crunch and fat. They are commonly sold frozen in North America and freezing is how you should keep them, because black walnut oil turns rancid quickly at room temperature. Grinding a third of a cup fine and folding it in gives a stronger flavour than a teaspoon of extract, plus a slightly denser and moister crumb.
Walnut extract plus molasses
different taste, similar texture
Ordinary walnut flavouring, corrected for the depth it is missing.
- Best for
- layer cakes, frostings, fudge, cookies, quick breads
This is the practical swap. Plain walnut extract is much gentler and sweeter, more generically nutty, and a black walnut cake made with it tastes pleasant and anonymous rather than distinctive. Molasses or black treacle puts back the dark, slightly bitter earthiness, and a quarter teaspoon of instant coffee granules does the same job if you would rather not add extra sweetness. Use a little more walnut extract than the recipe's black walnut quantity, since it is the weaker flavouring.
Toasted English walnuts ground fine, with molasses
different taste and texture
The pantry version, using the walnuts you can actually buy.
- Best for
- cakes and loaves, fudge, cookies, streusel toppings
Better than walnut extract alone, because real nut fat and toasted bitterness get you part of the way to black walnut's assertiveness. Toast the nuts at 175C or 350F for eight to ten minutes until they smell strongly nutty and the skins darken, and do not skin them, since the skins carry the tannic bitterness you want here. The result is still noticeably milder and sweeter than genuine black walnut, and it is a good cake.
Almond extract, used very sparingly
different taste, similar texture
Nothing like black walnut in flavour, but it does the same structural job in a cake.
- Best for
- layer cakes, buttercream, pound cake, fudge
Be clear about what this is: almond extract tastes of marzipan and cherry stone, which is the opposite end of the nut spectrum from black walnut's earthy bitterness. What it shares is the ability to turn a plain butter cake into something that reads as a nut cake rather than a vanilla cake. Use a quarter of the amount or less, because almond extract dominates everything it touches and half a teaspoon in a single cake is already a lot.
Maple extract or dark maple syrup
different taste, similar texture
A woodsy, sweet alternative that people genuinely like in the same recipes.
- Best for
- fudge, frostings, quick breads, penuche and pralines
Maple and black walnut share a woodsy register, and maple slots into black walnut recipes convincingly, especially fudge and frosting. It is sweeter and has none of the bitter edge, so the result tastes cosier and less grown-up. If you use the syrup rather than the extract, reduce another liquid in the recipe by a tablespoon.
There is no true substitute
different taste, similar texture
The honest answer for a recipe that is named after black walnut.
- Best for
- black walnut cake, black walnut fudge, black walnut ice cream
Black walnut is one of the genuinely irreplaceable flavours in American baking. There is no other nut, extract or spice that tastes winey, earthy and faintly bitter in that particular way, and everyone who grew up eating it will know instantly that it is missing. Every option above gives you a good cake. If the black walnut is the point, the extract keeps essentially forever in the cupboard and frozen nuts keep for a year, so it is worth ordering for next time.
Questions
5 questionsWhat is the difference between black walnut and regular walnut?
They are different species. English or Persian walnuts, the ones in every supermarket, are mild, buttery and slightly sweet. American black walnuts are much more assertive, with an earthy, winey, almost tarry note and real bitterness. Swapping one for the other in a recipe is not a small change, it is the difference between a nut cake and a black walnut cake.
Can I substitute regular walnuts for black walnuts?
You can, and the bake will be good but noticeably milder and sweeter. Toast them well and leave the skins on for bitterness, and add a teaspoon of dark molasses or a quarter teaspoon of instant coffee to the batter to push the flavour darker. It will still not fool anyone who knows black walnut.
Can I just leave it out?
In a recipe where black walnut is one flavour among several, such as a hummingbird cake or a spiced loaf, yes, and it will simply taste a little less complex. In a cake or fudge named after black walnut, leaving it out means you have made something else, so substitute rather than omit.
How much black walnut extract should I use?
Around ½ teaspoon for a two-layer cake or a batch of fudge, plus a teaspoon of vanilla, is a good starting point. Some old recipes call for a full teaspoon or more, which suits people who grew up with the flavour and tastes overpowering to everyone else.
Where do I buy black walnut extract?
Many American supermarkets stock it in the baking aisle next to the vanilla and almond extracts, and baking suppliers and online retailers carry it reliably. Frozen shelled black walnuts turn up in the freezer section in the autumn and winter in the regions where the trees grow.
Tips for substituting black walnut extract
5 tips- Black walnut extract is far stronger than vanilla and much stronger than plain walnut extract. Half a teaspoon flavours a whole layer cake, and a full teaspoon can tip into something soapy and medicinal, so start low even when the recipe says otherwise.
- Use it alongside vanilla, not instead of it. One teaspoon of vanilla with half a teaspoon of black walnut extract is the classic Southern balance, and the vanilla rounds off the bitterness so the nut flavour reads rich rather than harsh.
- The flavour survives baking well and actually improves overnight as it settles into the crumb, so black walnut cakes are better made a day ahead and kept covered at room temperature.
- Do not reduce the sugar in a black walnut recipe. The nut carries real bitterness and tannin, and the sugar is what makes that read as depth rather than as a fault.
- If you buy black walnuts in the shell, wear gloves and work outside. The husks stain hands, worktops and clothes a stubborn brown, which is why almost everyone buys them already shelled and frozen.
