NATIONAL LEMON CHIFFON CAKE DAY History: Harry Baker & the Brown Derby
The history of National Lemon Chiffon Cake Day traces back to a single inventor: Harry Baker, a Los Angeles insurance salesman who developed the chiffon cake recipe around 1927. Baker kept his formula secret for two decades, selling the cakes exclusively to the famous Brown Derby Restaurant in Hollywood, where they became a signature dessert. The Brown Derby’s clientele, Hollywood stars and industry figures, helped make the chiffon cake a celebrated American food item.
Until 1947, Baker guarded his recipe closely. That year, he sold the secret to General Mills, the American food giant, which published the recipe in a widely distributed pamphlet in 1948. The General Mills release described chiffon cake as “the first really new cake in 100 years,” a claim that captured the public’s imagination. The key innovation was replacing butter with vegetable oil, which kept the cake moist and gave it a uniquely airy texture that neither angel food cake nor butter cake could replicate.
When did National Lemon Chiffon Cake Day start? The precise founding year of the national day is not officially documented, but it has appeared consistently in national day calendars and food holiday resources since at least the early 2010s. It is now a recognized entry on major food holiday platforms.

What Is a Lemon Chiffon Cake? The Secret of Chiffon
A lemon chiffon cake is a light, tall, foam-style cake made with vegetable oil, whipped egg whites, cake flour, sugar, and fresh lemon juice or zest. It combines the richness of a butter cake with the airy texture of an angel food cake, producing a dessert that is moist yet feather-light. The lemon flavor comes from both zest and juice, giving it a bright, citrus-forward taste that makes it a popular spring and summer dessert.
The secret of chiffon lies in two things: oil and whipped egg whites. Unlike traditional cakes that use butter, chiffon cakes use oil, which stays liquid at room temperature and keeps the crumb tender. The whipped egg whites, beaten to stiff peaks, are folded gently into the batter, creating the signature lift and open crumb structure. This is what separates chiffon cakes from denser, butter-based cakes.
Lemon chiffon cake vs. regular cake, key differences:
- Fat source: Chiffon uses oil; most traditional cakes use butter.
- Texture: Chiffon is airy and springy; butter cakes are denser and richer.
- Egg technique: Chiffon separates eggs and folds in whipped whites; most cakes use whole eggs.
- Pan: Chiffon is baked in a tube pan and inverted to cool, like angel food cakes.
- Moisture: Oil-based chiffon stays moist longer than butter cakes.
Lemon chiffon vs. angel food cake: Both are foam cakes baked in tube pans, but angel food cakes use no fat at all and only egg whites, while chiffon cakes include oil and egg yolks. This gives chiffon a richer flavor and more golden color. The sponge angel food style is drier; chiffon is noticeably more tender.
How to Make Lemon Chiffon Cake From Scratch: Best Recipe for Home Bakers
A classic lemon chiffon cake recipe requires about 90 minutes from start to finish and uses pantry staples that most home bakers already have.

Ingredients (serves 10-12)
- 2 cups (225g) cake flour
- 1.5 cups (300g) real sugar, divided
- 1 tablespoon baking powder
- 0.5 teaspoon salt
- 0.5 cup (120ml) vegetable oil
- 7 large eggs, separated
- 0.75 cup (180ml) fresh lemon juice
- 2 tablespoons lemon zest
- 1 teaspoon cream of tartar (or substitute, see below)
Step-by-Step Instructions
- Preheat your oven to 325°F (165°C). Do not grease the tube pan, the batter needs to cling to the sides to rise.
- Whisk dry ingredients: Combine flour, 1 cup of sugar, baking powder, and salt in a large bowl.
- Add wet ingredients: Make a well in the center and add oil, egg yolks, lemon juice, and lemon zest. Whisk until smooth.
- Whip egg whites: In a clean bowl, beat the 7 egg whites with cream of tartar until foamy. Gradually add the remaining 0.5 cup sugar and beat to stiff, glossy peaks.
- Fold: Gently fold one-third of the egg whites into the yolk batter to lighten it, then fold in the remaining whites in two additions. Do not overmix, preserve the air.
- Bake: Pour into an ungreased 10-inch tube pan. Bake for 55-65 minutes until the top springs back when touched.
- Invert: Immediately invert the pan onto a bottle neck or its own feet. Cool completely upside down (about 1.5 hours) before removing.
- Glaze: Mix 1 cup powdered sugar with 2-3 tablespoons lemon juice for a simple glaze. Drizzle over the cooled cake.
Lemon Chiffon Cake Without Cream of Tartar: Substitutes
If cream of tartar is unavailable, substitute with an equal amount of white vinegar or fresh lemon juice (about 1 teaspoon per teaspoon of cream of tartar). Both are acids that stabilize the whipped egg whites and help them hold their structure during baking. The texture difference is minimal when the substitute is used correctly.
Common Mistakes Making Lemon Chiffon Cake
- Greasing the pan: This prevents the cake from climbing the sides and causes collapse.
- Underwhipping egg whites: Soft peaks won’t provide enough lift; aim for stiff, glossy peaks.
- Overmixing after folding: Deflates the air you worked to create.
- Removing from pan too soon: The cake must cool fully inverted or it will collapse under its own weight.
- Using all-purpose flour instead of cake flour: The higher protein content makes the cake tough rather than airy.

Lemon Chiffon Cake Storage, Dietary Variations & Health Notes
A freshly baked lemon chiffon cake lasts up to 2 days at room temperature when covered loosely, or up to 5 days refrigerated in an airtight container. For longer storage, individual slices can be frozen for up to 2 months. The oil-based formula helps the cake stay moist longer than butter-based cakes, which tend to dry out faster.
How Long Does Lemon Chiffon Cake Last?
- Room temperature (covered): 2 days
- Refrigerated (airtight): up to 5 days
- Frozen (wrapped slices): up to 2 months
Is Lemon Chiffon Cake Gluten-Free?
Standard lemon chiffon cake is not gluten-free because it uses cake flour, which contains gluten. However, a gluten-free version can be made by substituting a 1:1 gluten-free flour blend. The texture will be slightly denser, and the cake may not rise as high, but the flavor remains bright and lemony. For more on gluten-related baking, see the national gluten-free day tag for additional resources.
Lemon Chiffon Cake Vegan Alternative
A fully vegan lemon chiffon cake is challenging because the recipe depends heavily on egg whites for structure and lift. The closest vegan substitute is aquafaba (the liquid from canned chickpeas), which can be whipped to stiff peaks like egg whites. Replace each egg white with 3 tablespoons of aquafaba. The result is a lighter, slightly less stable cake but still recognizably chiffon in character. Vegan butter or coconut oil can replace standard vegetable oil without major texture changes.
Sugar and Health Notes
The lemon chiffon cake uses real sugar as a structural ingredient, it stabilizes the whipped egg whites and contributes to the cake’s golden crust. Reducing sugar by more than 25% can destabilize the meringue and cause the cake to collapse. For those monitoring sugar intake for health reasons, portion control is more practical than reformulating the recipe. The cake’s oil base does mean it contains less saturated fat than a comparable butter cake, which is a modest health advantage.
Lemon Chiffon Cake Recipes & Resources for Home Bakers
Home bakers looking for lemon chiffon cake recipes and resources have a wide range of options, from classic General Mills-style formulas to modern variations with glazes, fillings, and flavor twists. The base recipe is highly adaptable, the lemon can be swapped for orange, lime, or grapefruit, and the glaze can be replaced with whipped cream or a light cream cheese frosting.
