The applesauce and erythritol are the heart of this recipe. Muir Glen unsweetened applesauce is my go-to—it’s smooth and never watery. For erythritol, Lakanto or Wholesome Sweeteners brands work best; avoid blends with fillers. The apples should be firm and crisp—Granny Smiths or Honeycrisp hold up better than Red Delicious when baking. If you can’t find powdered erythritol, blend granulated in a food processor for a finer texture. The butter matters too—Plugrá or Land O’Lakes unsalted gives the best flavor without overpowering the spices.
No erythritol? Monk fruit sweetener at a 1:1 ratio works, though texture may differ slightly. Short on apples? Substitute with unsweetened applesauce plus 1 tbsp lemon juice to mimic acidity. The baking soda is non-negotiable—it’s what creates that tender crumb. For the streusel, Trader Joe’s old-fashioned oats are perfect, but any rolled oats will do. If you’re avoiding sugar entirely, skip the brown sugar in the topping and add an extra 1 tbsp erythritol. The vanilla extract should be pure—Nielsen-Massey or McCormick are reliable brands.
Store baked cake wrapped in plastic at room temperature for 3 days or refrigerated for 1 week. The streusel topping stays crisp best if kept dry—cover it loosely with parchment. For longer storage, slice and freeze portions for up to 3 months. Reheat slices at 350°F for 5 minutes to restore freshness. This cake reheats beautifully—perfect for a quick dessert when you’ve got company dropping by unexpectedly.
Why You'll Love This Recipe
- No-Fuss Mixing: Mixing this cake is basically stirring and pouring—no fancy techniques, no waiting for dough to chill. The unsweetened applesauce keeps things moist without extra effort, and the erythritol blends right in like flour. Honestly, I’ve made it in my daughter’s mismatched bowls when the stand mixer was “occupied” (aka watching cartoons).
- Applesauce Magic: That unsweetened applesauce isn’t just a substitute—it’s the secret. It softens the crumb, balances the erythritol sweetness, and gives it that just-baked aroma without a single drop of oil or syrup. (Yes, even on a Tuesday night, this smells like a bakery.)
- Leftovers That Last: This cake stays fresh for days—no weird aftertaste, no dry crumb—because the applesauce and eggs lock in moisture. I’ve packed slices for lunches, reheated them in the toaster, and even frozen portions for lazy mornings. (Pro tip: the erythritol keeps it from getting gummy.)
- Budget Bakery Feel: Flour, applesauce, eggs—these are pantry staples that won’t break the bank. I’ve made this for birthday parties, potlucks, and “I just need cake” moments, and no one ever guesses it’s sugar-free. Between us, it’s my go-to when I’m low on cash but still want something special.
Step-by-step instructions for naturally sweetened apple cake
Here's the method for a perfectly moist, sugar-free apple cake with rich cinnamon flavor.
👨🍳 Step 1: Prepare the Apples and Streusel Topping
Peel, core, and dice the 3 medium Red Delicious Apples into ¼-inch pieces. Toss them with 1 tablespoon Vanilla Extract and set aside. This step prevents oxidation and adds subtle vanilla depth to the apples.
In a separate bowl, combine the 0.5 cup Oat Flakes, 0.25 cup Light Brown Sugar, 1 tablespoon Ground Cinnamon, and 0.5 cup Unsalted Butter (softened). Use your fingers to work the butter into the dry ingredients until it forms a crumbly texture. This creates the perfect streusel topping that will caramelize beautifully during baking.
👨🍳 Step 2: Mix the Cake Batter
Preheat your oven to 350°F and grease an 8-inch round cake pan. In a large mixing bowl, combine the 2.5 cups All-Purpose Flour, 1 teaspoon Baking Soda, 0.5 teaspoon Salt, 2 teaspoons Ground Cinnamon, and 0.5 teaspoon Ground Nutmeg. Whisk these dry ingredients together until fully incorporated.
In a separate bowl, cream together the 1 cup Unsalted Butter (softened) and 0.75 cup Erythritol on medium speed until light and fluffy, about 3-4 minutes. Add the 2 whole Large Eggs, one at a time, mixing well after each addition. Stir in the 1 cup Unsweetened Applesauce and 1 tablespoon Vanilla Extract until just combined. Gradually add the dry ingredients to the wet mixture, mixing on low speed just until combined. Avoid overmixing to maintain a tender crumb.
🥘 Step 3: Assemble and Bake the Cake
Gently fold the prepared apple mixture into the cake batter. Pour half of the batter into the prepared cake pan and spread evenly. Sprinkle half of the streusel topping over the batter, then add the remaining batter and top with the remaining streusel. The streusel should be evenly distributed for consistent browning.
Bake for 45-50 minutes, or until a toothpick inserted into the center comes out clean and the top is golden brown. The cake should spring back slightly when gently pressed in the center. If the top browns too quickly, tent loosely with aluminum foil to prevent overbrowning while ensuring the center cooks through.
⏰ Step 4: Cool and Finish
Remove the cake from the oven and let it cool in the pan for 15 minutes. Then transfer to a wire rack to cool completely. While cooling, sprinkle the top with 0.25 cup Granulated Erythritol for a subtle sweet, crystalline finish that enhances the cinnamon flavor.
This cooling period is crucial for developing the cake's texture. The erythritol topping should be applied when the cake is still warm but not hot to the touch. Serve slices at room temperature for the best texture and flavor balance between the moist cake and caramelized streusel.
Pro Tips For Making Apple Cake Recipe Without Sugar
- Whisk Eggs Like Butter: Beat those eggs until they’re pale and almost tripled in volume—about 3-4 minutes with a hand mixer. I learned this the hard way: under-whisked eggs mean a dense cake, and no one wants a brick disguised as dessert.
- Chill the Batter: Pop the mixed batter in the fridge for 15-20 minutes before baking. This isn’t just about waiting—it lets the flour absorb moisture evenly, so your cake rises instead of sinking. (Yes, even if you’re impatient like me.)
- Measure Applesauce Right: Use a scoop or spoon to pack unsweetened applesauce into the measuring cup—don’t eyeball it. Too much liquid = a gummy mess; too little = dry crumbs. Aim for 1 cup packed firmly, no extra drips.
- Bake Until Golden: Skip the toothpick test—this cake’s done when the top is deep golden (not just pale) and the edges pull away slightly. Overbaking dries out the erythritol’s natural sweetness, and you’ll end up with a sad, crumbly result.
Troubleshooting this dish
Dense Batter Fix
If your batter looks too thick after mixing, add 1-2 tablespoons of warm water to loosen it. The applesauce and erythritol combo can make the batter denser than traditional cake mixes. I’ve found that Muir Glen unsweetened applesauce is slightly thicker than store brands, so adjust gradually.
Overmixing is the real culprit—stop as soon as the dry ingredients disappear into the wet. 💡
Streusel Not Crumbly
If your streusel turns into a doughy mess, chill it for 15 minutes before baking. The butter needs to firm up slightly to create those perfect crumbly pockets. For extra insurance, use cold butter straight from the fridge and cut it into small cubes before mixing.
If it still sticks together, add 1 tablespoon more oat flakes to absorb excess moisture. 🥄
Cake Too Dry
Dry cake usually means overbaking or insufficient moisture. First, check your baking time—45-50 minutes is the sweet spot at 350°F. If it’s done early, the center won’t be fully set. For extra moisture, add 2 tablespoons of Greek yogurt to the batter (it adds richness without sugar).
Also, make sure your apples are fully diced and not juicy—pat them dry with a paper towel if needed. 🍏
Soggy Bottom
This happens when the cake pan isn’t properly greased or the batter sits too long before baking. Always use butter or baking spray to grease your 8-inch pan, and bake within 30 minutes of mixing.
For extra insurance, place the pan on a baking sheet to catch any drips. If you notice the bottom browning too quickly, tent the cake with foil after 25 minutes. 🔥
Erythritol Clumping
Erythritol clumps easily, especially in humid kitchens. Sift it through a fine-mesh sieve before measuring to break up any lumps. If you’re using granulated erythritol, pulse it in a food processor for 10-15 seconds to create a powdery consistency.
Store it in an airtight container with a silica gel packet to prevent future clumping. 🌬️
Uneven Baking
If one side browns faster than the other, rotate the pan halfway through baking (after 25 minutes). This ensures even heat distribution. Also, avoid opening the oven door too early—temperature fluctuations cause uneven rising.
If your oven runs hot, reduce the temperature to 325°F and add 5-10 minutes to the bake time. 🌡️

Frequently asked questions
Can I use regular sugar instead of erythritol in this recipe?
You can substitute regular sugar for erythritol, but the texture and sweetness will differ. Use a 1:1 ratio and expect a denser cake with more pronounced sweetness. The applesauce already provides natural sweetness, so you may want to reduce the sugar by 25% if you're sensitive to sweetness. This version is designed to highlight the natural flavors of apples and spices without refined sugar.
What's the best way to store leftover apple cake?
Store your sugar-free apple cake in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for 1 week or freeze slices for 3 months. The streusel topping stays best when kept dry—cover it loosely with parchment paper. To reheat, warm slices at 350°F for 5 minutes to restore freshness.
Can I make this cake gluten-free?
Yes, but you'll need to substitute the all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill). Add 1 extra teaspoon of xanthan gum to help bind the cake. The texture may be slightly denser, but it will still be moist and flavorful. Make sure your oats are certified gluten-free for the streusel topping.
Why does my cake taste bland without sugar?
The natural sweetness comes from the apples and erythritol, but you can enhance the flavor by adding 1 extra teaspoon of cinnamon or ½ teaspoon of vanilla bean paste to the batter. A pinch of cardamom or allspice also complements the apples beautifully. The key is balancing the spices—too much can overpower the delicate apple flavor.
Can I bake this cake in a different pan size?
For an 8-inch round pan, this recipe is perfect. If using a 9-inch pan, reduce the bake time by 5-7 minutes (check at 40 minutes). For a 9x13-inch pan, spread the batter evenly and bake for 35-40 minutes. The thickness matters—aim for about 1.5 inches of batter depth for even baking.
