Lemon Pudding Cake (Sugar-Free)
- 1/2 cup granulated sugar-free sweetener
- 1/2 cup all-purpose flour
- 3 large eggs, separated
- 1 cup whole milk
- 1/3 cup fresh lemon juice
- 1 tsp finely grated lemon zest
- 3 tbsp unsalted butter, melted

The flour and sweetener create the sponge base, while the eggs, milk, and butter form the creamy pudding. Fresh lemon juice and zest add bright, zesty flavor.
How to Make Sugar-Free Slow Cooker Lemon Pudding Cake
This pudding cake is mixed in bowls, folded with whipped egg whites, and cooked in a slow cooker until set on top and creamy underneath.
Prepare the Slow Cooker
Lightly butter the inside of a 4- to 6-quart oval slow cooker. This prevents sticking and helps with easy serving.
Mix the Dry Ingredients
Whisk the granulated sugar-free sweetener, all-purpose flour, and salt in a medium bowl until fully combined.
Make the Lemon Mixture
Add the egg yolks, whole milk, fresh lemon juice, lemon zest, and melted butter to the dry ingredients.
Whisk until smooth. The mixture will be thin and creamy.
Whip the Egg Whites
Beat the egg whites in a clean, dry bowl until stiff peaks form. This creates the light, airy sponge layer.
Gently fold the egg whites into the lemon mixture in three additions.
Fold just until combined to keep the batter light. Overmixing can deflate the egg whites.
Cook and Serve
Pour the batter into the prepared slow cooker.
Cover and cook on high for 2 to 2 1/2 hours, until the top is set and lightly golden with a soft pudding layer underneath.
Turn off the slow cooker and remove the lid.
Let rest for 20 to 30 minutes. This allows the pudding to settle and thicken slightly.
Spoon into bowls and serve warm or chilled.
Texture and Flavor
This lemon pudding cake has a soft, tender sponge top with a warm, creamy lemon pudding underneath. The top is light and airy, while the bottom is rich and smooth.
The flavor is bright and refreshing, with fresh lemon juice and zest providing vibrant citrus notes. The creamy pudding layer adds sweetness and richness, while the sponge top adds lightness.
Served warm, it feels like a comforting, indulgent dessert that is perfect for any occasion.
Tips for the Best Results
A few small details can help your lemon pudding cake turn out perfectly.
Use Fresh Lemon
Use fresh lemon juice and zest for the brightest flavor. Bottled lemon juice can taste flat.
Keep Egg Whites Clean
Keep the egg whites free from yolk so they whip properly. Even a small amount of yolk can prevent stiff peaks.
Fold Gently
Fold the egg whites gently to create a light sponge layer. Overmixing can deflate the batter.
Do Not Overcook
Do not overcook because the bottom should remain creamy and pudding-like. Check for doneness at 2 hours.
Serve with Whipped Cream
Serve with sugar-free whipped cream, if desired. This adds richness and sweetness.
Let It Rest
Let the cake rest for 20 to 30 minutes before serving. This allows the pudding to settle.
Easy Variations
This recipe is easy to customize with different flavors and toppings.
Add Blueberries
Fold 1/2 cup of fresh blueberries into the batter for a lemon-blueberry version.
Add Vanilla
Add 1 teaspoon of vanilla extract to the lemon mixture for a warmer note.
Add Raspberry
Replace the lemon with raspberry juice and zest for a different citrus flavor.
Make It Dairy-Free
Use unsweetened almond milk and dairy-free butter for a dairy-free version.
Add Mint
Garnish with fresh mint leaves before serving for a fresh, aromatic touch.
Serving Ideas
This lemon pudding cake is best served warm or chilled. A dollop of sugar-free whipped cream or a sprinkle of lemon zest makes it feel extra special.
Extra berries or a drizzle of sugar-free lemon syrup adds brightness and texture. It is perfect for spring gatherings, celebrations, potlucks, or any time you want a light, refreshing dessert.
Storage Tips
Store leftovers covered in the refrigerator for up to 3 days.
Keep the pudding cake covered with plastic wrap or transfer individual servings to an airtight container.
For the best texture, serve it warm. Reheat gently in the microwave or slow cooker before serving.

Common Mistakes to Avoid
A few simple mistakes can affect the texture of this lemon pudding cake.
Using Bottled Lemon Juice
Bottled lemon juice can taste flat. Use fresh lemon juice for the brightest flavor.
Getting Yolk in Egg Whites
If yolk gets into the egg whites, they may not whip properly. Separate the eggs carefully.
Overmixing the Egg Whites
Overmixing can deflate the egg whites. Fold them gently into the batter.
Overcooking
Overcooking can make the pudding layer too firm. Cook until the top is set but the bottom is still creamy.
Not Letting It Rest
