Vinegar Cake From World War 2: A Wartime Delight That Stood the Test of Time

This is the cake that came out of WWII rationing kitchens. No eggs. No butter. No milk. Just pantry basics and a clever chemistry trick.

The secret is vinegar. When it hits baking soda, it foams up and lifts the cake the way eggs and butter usually do.

I baked this expecting it to taste flat and pantry-empty. It turned out moist, tender, and surprisingly chocolatey when I added cocoa.

What Is Vinegar Cake?

Vinegar cake is a moist, eggless, butterless, milkless cake leavened by the acid-base reaction between vinegar and baking soda. It tastes nothing like vinegar (the smell bakes off completely).

It is also known by several other wartime names: Wacky Cake, Crazy Cake, Depression Cake, and War Cake. All variations of the same idea: bake a real cake when you have almost nothing in the pantry.

A Quick History of Vinegar Cake

Vinegar cake first appeared during World War I, when sugar, eggs, and butter were rationed across the US, Canada, and the UK. Bakers needed something that tasted like a treat without using the precious ingredients soldiers needed.

The Great Depression made it a regular feature of American kitchens. By WWII, when rationing returned, the recipe was already famous and got widely shared in newspaper columns, church cookbooks, and Ministry of Food pamphlets.

British bakers leaned into a fruity version with raisins and a touch of jam. American bakers favored a chocolate version (the legendary “Wacky Cake”). Canadian bakers used molasses and spices to create a denser “War Cake.”

All three traditions survive today as nostalgia recipes and as serendipitously vegan cakes that work for anyone with allergies.

Times and Yield

• Prep time: 10 minutes
• Bake time: 35-40 minutes
• Total time: 50 minutes
• Yield: One 8-inch round cake (~8 slices)
• Difficulty: Beginner

Equipment

• 2 large mixing bowls (I love this mixing bowl set)
• Whisk or wooden spoon (Love environmet & style? Get this bamboo spoon set)
• Measuring cups and spoons
• 8-inch round cake tin
• Parchment paper
• Cooling rack

Ingredients

• 1½ cups all-purpose flour
• 1 cup granulated sugar
• 1 tsp baking soda
• ½ tsp salt
• 3 tbsp unsweetened cocoa powder (optional, for chocolate version)
• 1 tbsp white vinegar (or apple cider vinegar)
• 5 tbsp vegetable oil
• 1 tsp vanilla extract
• 1 cup water

Instructions

Step 1: Preheat the Oven and Prep the Pan

Preheat oven to 350°F (175°C). Line the bottom of an 8-inch round cake tin (this 6 piece set will hook you up for a long time!) with parchment and lightly grease the sides.

Step 2: Mix the Dry Ingredients

In a large bowl, whisk together the flour, sugar, baking soda, salt, and cocoa powder if using.

Whisk thoroughly. Pockets of unmixed baking soda will leave bitter spots in the cake.

Step 3: Combine the Wet Ingredients

In another bowl, whisk together the water, oil, vinegar, and vanilla.

Step 4: Combine Wet and Dry

Make a well in the center of the dry ingredients. Pour the wet mixture in.

Stir gently until just combined. A few small lumps are fine. Overmixing will toughen the cake.

Step 5: Pour and Bake

Pour the batter into the prepared tin. Tap it gently on the counter to release air bubbles.

Bake for 35 to 40 minutes. A toothpick in the center should come out clean.

Step 6: Cool

Cool in the tin for 10 minutes, then transfer to a wire rack to cool completely.

Tips and Troubleshooting

• Cake didn’t rise? Old baking soda. The vinegar-soda reaction is the only leavener here, so freshness matters.
• Tastes like vinegar? It shouldn’t. The acid bakes off completely. If you smell vinegar, you used too much. Stick to 1 tablespoon.
• Tough crumb? You overmixed. This batter is fine with lumps. Stir just until combined.
• Sunken middle? Oven temp too high or you opened the door early. Use an oven thermometer to verify.

Variations Worth Trying

• British wartime fruit version: Skip the cocoa. Add ½ cup raisins or sultanas and 1 tsp mixed spice. The Ministry of Food’s official version.
• Wacky Cake (chocolate): Use the cocoa version above. Mix the dry ingredients directly in the cake pan (this 6 piece set will hook you up for a long time!), dig three wells, pour in oil, vinegar, and vanilla separately, then add water and stir. The “wacky” mixing method.
• Spiced War Cake: Add 1 tsp cinnamon, ½ tsp nutmeg, ¼ tsp cloves and ½ cup raisins. Canadian wartime classic.
• Modern glaze: Top with a simple powdered sugar + lemon juice glaze, or chocolate ganache.

How to Serve It

Wartime: plain slice with a cup of weak tea (rationed). Maybe a scrape of jam if anyone had any.

Modern: dust with powdered sugar, top with whipped cream and fresh berries, or layer with frosting for a vegan-friendly birthday cake.

How to Store and Reheat

Stays moist for 2 to 3 days at room temperature in an airtight container. Up to a week in the fridge.

Freezes beautifully. Slice, wrap individually, freeze up to 3 months. Thaw at room temperature in 30 minutes.

Frequently Asked Questions

Why does vinegar cake work without eggs or butter?

The acid in vinegar reacts with baking soda to create carbon dioxide bubbles, which leaven the cake the same way eggs would. The oil replaces butter for moisture and tenderness.

Can you taste the vinegar in vinegar cake?

No. The vinegar fully reacts with the baking soda and bakes off during cooking. The finished cake tastes like a normal cake.

Is vinegar cake the same as Wacky Cake?

Wacky Cake is the chocolate American version of vinegar cake. They use the same chemistry, just different additions and mixing methods. Wacky Cake is famously mixed directly in the baking pan (this 6 piece set will hook you up for a long time!).

Is vinegar cake vegan?

Yes. Vinegar cake was created for wartime rationing, not for vegans, but it happens to contain no animal products.

What kind of vinegar should I use?

White vinegar is most common because it has no flavor. Apple cider vinegar works too and adds a faint fruity note. Avoid balsamic or wine vinegars, which are too strong.
