Frequently Asked Questions
Is this cake truly safe for diabetics?
Yes, this cake contains no added sugar. The sweeteners used—erythritol and stevia—have a glycemic index of zero and do not raise blood glucose levels. However, the applesauce and flour do contain natural carbohydrates, so the cake is not “zero carb.” A slice contains approximately 8–12 grams of net carbs, depending on the specific ingredients. It should be consumed as part of a balanced meal plan, and individuals with diabetes should monitor their own blood sugar response, as each person is different. Always consult with a healthcare professional regarding specific dietary choices. The cake is a far better option than a traditional sugar-laden dessert, and it can be a wonderful treat within a diabetic-friendly lifestyle.
Can I use honey or maple syrup instead of sugar-free sweetener?
If you are not diabetic and are simply looking to reduce refined sugar, you can use honey or maple syrup, but the cake will no longer be sugar-free or low on the glycemic index. Honey and maple syrup are natural sugars that will raise blood sugar. If you do use them, replace the powdered erythritol and stevia with ½ cup of honey or maple syrup, and reduce the applesauce by ¼ cup to account for the added liquid. The cake will be denser and darker. For a truly diabetic-friendly cake, stick with the sugar-free sweeteners.
My cake turned out a little dense. What went wrong?
Dense cake can result from overmixing the batter, using old baking powder, or not incorporating enough air. The optional whipped egg white is a great insurance policy against density—it adds volume and a lighter crumb. Also, make sure your applesauce is at room temperature; cold ingredients can inhibit rise. Next time, try the egg white method, and ensure your baking powder is fresh. You can also replace the whole wheat pastry flour with white whole wheat flour or a mixture of all-purpose and whole wheat for a lighter texture.
Can I make this cake without eggs?
Yes, you can use flax eggs as described. The cake will be a bit denser and more moist, but still delicious. To get a better rise without eggs, increase the baking powder to 1½ teaspoons and consider adding ½ teaspoon of apple cider vinegar to react with the baking soda for extra lift. A combination of applesauce and a bit of yogurt can also help mimic the richness of eggs. The vanilla glaze remains the same.
What can I use instead of applesauce?
Mashed ripe banana (the same amount) works beautifully, though it will add a banana flavor and a bit more natural sugar. Plain Greek yogurt or mashed pumpkin puree are also good substitutes, each lending a different flavor and nutritional profile. If you use pumpkin, add a little pumpkin pie spice for a seasonal treat. The key is to replace the applesauce with a similar amount of a moist puree.

Prep Time:
15 minutes
Cook Time:
40–50 minutes
Cool Time:
1–2 hours
Total Time:
About 2 hours 45 minutes
Servings:
10–12 slices
Ingredients
For the Cake:
- 1 cup unsweetened applesauce
- ½ cup powdered erythritol (confectioners-style, such as Swerve)
- 10–15 drops liquid stevia (or to taste)
- 2 large eggs, at room temperature
- 1 large egg white, at room temperature (optional, for extra lift)
- Juice and zest of 2 medium lemons
- 2 teaspoons vanilla extract
- 2 cups whole wheat pastry flour (or 1:1 gluten-free flour blend)
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
For the Vanilla Glaze:
- ½ cup powdered erythritol (confectioners-style)
- 1–2 tablespoons unsweetened almond milk (or milk of choice)
- 1 teaspoon vanilla extract
Instructions
- Preheat oven to 350°F (175°C). Line a 9×5-inch loaf pan with parchment paper and lightly grease.
- In a large bowl, whisk together the applesauce, powdered erythritol, liquid stevia, eggs (and extra yolk if not using white), lemon juice, lemon zest, and vanilla until smooth.
- Add the dry ingredients: flour, baking powder, baking soda, and salt. Stir gently until just combined—do not overmix.
- (Optional) Whip the egg white in a separate bowl until stiff peaks form. Gently fold the whipped white into the batter in three additions, until no white streaks remain.
- Pour the batter into the prepared pan and smooth the top. Bake for 40–50 minutes, until a toothpick inserted in the center comes out clean and the top is golden.
- Cool in the pan for 10 minutes, then lift out by the parchment and cool completely on a wire rack (about 1–2 hours).
- Make the glaze: Whisk together powdered erythritol, 1 tablespoon milk, and vanilla until smooth. Add more milk a little at a time until the glaze is pourable but thick. Drizzle over the cooled cake. Let set for 20–30 minutes before slicing.
Notes
- Use powdered erythritol for the smoothest texture; granulated sweetener will leave a gritty feel. If you only have granulated, blend it into a fine powder first.
- The optional whipped egg white makes the cake lighter and airier. If you skip it, the cake will be denser but still delicious.
- For a vegan version, use flax eggs and a gluten-free flour blend. The cake may need an extra 5–10 minutes of baking time.
- Store covered at room temperature for up to 3 days, in the fridge for 5 days, or freeze unglazed for up to 3 months. Glaze before serving for the best appearance.
