Gâteau Nantais originated in Nantes in western France. Made with generous amounts of butter, eggs and almond flour, the cake’s crumb is rich, moist and pleasantly dense, and becomes even more so after it’s brushed with a rum syrup. The classic finish is a rum icing, but with rum already in both the cake and syrup, we opted instead for a bracing lemon glaze that brings out the lemon zest in the cake, and a sprinkle of toasted sliced almonds. You can serve the cake as soon as the glaze sets, but its flavor and texture improve if allowed to rest overnight at room temperature. If storing for longer, cover and refrigerate (up to three days), but bring to room temperature before serving. If you have a dark, non-stick cake pan—which transfers heat more quickly than lighter aluminum—reduce the temperature to 325°F and bake for the same time.

Tip

Don’t use a small saucepan to make the syrup, and don’t forget to remove the pan from the burner before pouring in the rum. These steps help ensure that the alcohol won’t ignite. After removing the cake from the pan, don’t re-invert it—leave it bottom side up, as the perfectly flat surface is easy to glaze. Finally, don’t allow the cake to cool before brushing on the syrup; absorption is better if the cake is still hot.

Crowd favorite
This gateau was a huge favorite at a birthday party. The flavors are excellent and the cake is light and so moist with a perfect crumb. I’ve made it a few more times.

Wonderful combination of flavors
Renee S.

Hello,
My daughter, home from college, made this cake on Christmas day for our dinner that evening. Is the amount of salt in the glaze correct? No one at our table found it edible. It that a mistake? Shouldn't it be a pinch of salt?

Renee Shannon

Michaela H.

I agree with Renee. Seems like a pinch of salt would be more than enough to cut the sweet and bring out flavor.

Janelle C.

Hi Renee,

The amount is correct. Feel free to adjust to your taste, but in the future make sure you're using kosher salt. Different salt varietals will alter the taste.

The recipe says to use table salt in the cake as well as the glaze, but here you are saying to be sure to use kosher salt in the glaze. Which is correct? Also, I've never baked with salted butter before and I'm surprised to see it called for in this cake. Is there a reason you used it for this recipe?

Lynn C.

Hi Nancy -

We recently changed all of our baking recipes to call for table salt rather than kosher salt as the variation in grain size among brands was causing inconsistent results in the recipes. This comment by Janelle predates that change so the amount of table salt called for in the recipe is correct. We always call for salted butter in all of our recipes. We’ve done our homework and after testing salted versus unsalted butter in a number of savory and baking recipes, we didn’t find any measurable difference between the two. The small amount of salt in salted butter is undetectable when cooked or baked in a recipe, we found. Still, we have a preference between the two. Though most culinary professionals and publications will recommend using unsalted butter, we prefer the salted kind because it tastes better when you’re not cooking with it. Unsalted butter doesn’t cut it on toast! Since we prefer to stick with one kind, salted butter is our choice.

1 unit of Diamond Crystal Kosher Salt = ¾ unit Morton Kosher Salt = ½ unit of table salt. I believe that Milk Street uses Diamond Crystal Kosher Salt in their recipes. So, ½ teaspoon of Diamond Crystal Kosher Salt would convert to ⅜ teaspoon of Morton Kosher Salt, or ¼ teaspoon of table salt. Hope this helps.

Needs more rum syrup. We made this for Christmas and while the flavor was good, the cake was a bit dry. We made it again last night and increased the amount of rum to 2/3 c and and water somewhat, kept the spices the same. The cake was appreciably moister and more delicious. With these adjustments, this will become our special occasion go-to dessert.

John B.

Hello Marybeth - in your comment, you write "2/3 c and and water somewhat." As I want to take your suggestion, may I ask what you had intended to say there? Thanks so much!

Sara S.

I replaced the regular flour with coconut flour and switched orange instead of lemon. My family loved it.

Rachel H.

We made this cake following the recipe exactly and it was moist and delicious. The lemon glaze was perfect. We will be making this cake again very soon.

Andrew G.

I made this cake gluten-free for my wife for Valentine's Day. It was fantastic. In my recent quarantine shopping, I made a purchase, which has me asking would Meyer lemons works in this cake?

Rajat S.

i am thinking of making this for a friend who is allergic to Gluten and dairy. Is there a frosting you could suggest for this

Janelle C.

Hi Rajat,

The glaze is both gluten- and dairy-free.

Made this recipe for a dinner party and it was a smash hit...not a drop left to enjoy at a later date. Will definitely do it again and the recipe was perfect...no changes were necessary!

Sarah R.

Struggling with this cake collapsing in the middle after the syrup is applied. Also, the glaze was too runny and ended up mostly absorbing into the cake. Will give this another try, I guess.

Lynn C.

Hi Sarah -

Was the cake fully baked when you applied the syrup? Since baking times can vary, we always recommend following the visual clue (in this case, "bake until the cake is deep golden brown and the center of the cake springs back when gently pressed") rather than the baking time. For the glaze, did you ensure that the cake was room temperature before adding it? I have always found that the glaze is actually quite thick so it's possible that the cake was too hot when you added it. Hope that helps for next time.

I know that "regular" rum comes in a light or dark version (which I do not already have). I do, however, have some Captain Morgan's Original Spiced Rum. Has anyone tried this instead? Should I omit or reduce the allspice and peppercorns since the rum is already spiced? Your thoughts, Milk Street?

Lynn C.

Hi William -

I would definitely cut back on the allspice and black peppercorns since spiced rum is already pretty heavily flavored with these spices.

Leslie L.

My wife is Russian and has Celiac's. She doesn't often get to eat desserts. I used cassava flour instead of wheat flour (cassava is my go to). My wife told me this is the BEST almond/rum cake she has ever tasted.

Lee R.

can this be made with all almond flour?

April D.

Lee - yes, this cake can be made exclusively with almond flour, though it will be a bit more dense that with the small added amount of all-purpose flour. That's okay - the cake is meant to be rich and dense! If the goal is to make the cake gluten-free, you could also use a 1:1 GF baking blend in place of the 80 grams of AP flour, or experiment with adding a second GF flour (like the cassava that Leslie experimented with above).

Deborah L.

Hi! I live in Denver, Colorado (altitude is 5280 ft). What adjustments do I need to make to the recipe? I have made other almond cake, and the cake collapses in the middle. Thank you.

Lynn C.

Hi Deborah -

We haven't tested this at high altitude so we can't give you specific recommendations for this particular recipe. King Arthur Flour has some good tips on how to change recipes at high altitude which you can find here - https://www.kingarthurbaking.com/learn/resources/high-altitude-baking. Good luck!

I live at 7000’ and made this recipe without modifications and it came out very nice. I went with the stock recipe because this cake doesn’t require baking powder or baking soda and thus appears to have a simpler baking chemistry. I was concerned that the semi-high speed egg mixing would result in a fallen cake but my concerns were unfounded. I ended up with an awesomely moist cake that didn’t fall.

Deborah L.

Thank you for your comment! Your comment is currently under moderation and will appear shortly.

Kathy M.

Yikes! Looking in the oven and the cake has ridden a bit ABOVE the edge of the cake pan. About 1/4 inch. Twelve minutes to go and the center is sunken. Well, we shall see what I end up with.

Nancy J.

Delicious, easy and very moist. Be careful with the glaze - it goes from incredibly thick to runny quickly. Add that 3rd tablespoon of lemon juice very gradually. I only ended up using a total of 2.5 tablespoons the second time I made it and that was perfect.
