The apples make or break this cake. Red Delicious adds sweetness while Granny Smith brings tartness—both should be firm, not mealy. Whole Foods or local markets often have fresher apples than grocery stores. Dice them small (about 1/4-inch pieces) so they distribute evenly. If you can't find Granny Smith, Honeycrisp works too—just add a pinch more cinnamon to balance the sweetness. The applesauce? Grab the unsweetened kind from the baking aisle—Mott's is reliable, but any brand will do.
No applesauce? Unsweetened pumpkin puree works in a pinch, though the texture will be slightly denser. Swap the butter for apricot jam if you're avoiding dairy entirely—use half the amount. The egg whites need to be room temperature for maximum volume, so take them out of the fridge 30 minutes before baking. For the glaze, powdered sugar from the cake aisle dissolves more easily than granulated. If you're feeling fancy, add a splash of orange juice to the glaze for extra zing.
This cake keeps well for 4 days in an airtight container at room temperature, though it's best enjoyed fresh. The glaze sets as it cools, so don't rush it—patience gives you that professional finish. For make-ahead baking, prepare the cake batter the night before and refrigerate. The apples will soften slightly, but the texture stays perfect. Slice and serve with a dollop of Greek yogurt for extra protein, or keep it classic with a scoop of vanilla ice cream.

Step-by-step instructions for lightened-up apple cake
Here's how to create tender layers with just the right balance of sweetness and zing.
Prep the Apples and Make the Filling
Peel and finely dice the 2 medium Red Delicious apples and 2 medium Granny Smith apples, keeping them separate for now. Toss the Red Delicious pieces with 1 tablespoon lemon zest and 1 tablespoon lemon juice to prevent browning. Set aside in a bowl.
In a separate small bowl, whisk together 1 cup unsweetened applesauce, 1 teaspoon vanilla extract, and 0.5 cup light brown sugar. This mixture will keep your cake moist while reducing fat. The applesauce replaces butter here, giving you that tender crumb without heaviness.
Combine the Granny Smith apple pieces with the applesauce mixture, stirring until evenly coated. The tart Granny Smith balances the sweetness of the Red Delicious, creating a perfect flavor profile. Let this filling sit while you prepare the cake batter.
Mix the Dry Ingredients and Whisk the Wet
In a medium bowl, sift together the 2 cups all-purpose flour, 2 teaspoons baking powder, 1.5 teaspoons ground cinnamon, and 0.5 teaspoon ground nutmeg. Whisk gently to combine—don't overmix or you'll develop gluten, which makes the cake tough.
In a separate large bowl, beat the 5 large egg whites until they form soft peaks. Gradually add the 1 cup granulated sugar while continuing to beat until the mixture is glossy and holds stiff peaks. This step is crucial for creating light, airy layers in your cake.
Reduce the speed to low and gently fold in the 0.5 cup cold cubed unsalted butter until just combined. The butter should be evenly distributed but still visible in small flecks—this ensures tenderness without heaviness. Be careful not to overmix at this stage.
Combine Wet and Dry Ingredients
Alternate adding the dry ingredients and the apple-applesauce mixture to the egg white mixture, beginning and ending with the flour mixture. Use a spatula to gently fold everything together until just combined. The batter should be thick but pourable—if it's too stiff, you can add 1-2 tablespoons milk (though we're keeping this truly low-fat).
Fold in the prepared Red Delicious apple mixture last, reserving about ½ cup for the top layer. The filling should be evenly distributed throughout the batter. This step ensures each bite has that perfect apple flavor without making the cake too dense.
Bake the Cake Layers
Preheat your oven to 350°F and grease two 8-inch round cake pans, lining the bottoms with parchment paper for easy removal. Divide the batter evenly between the pans, spreading it out to create even layers.
Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. The edges should be golden brown, but the tops might look slightly underdone—this is normal for a light cake. Rotate the pans halfway through for even baking.
Once done, remove from the oven and let the cakes cool in their pans for 10 minutes. Then transfer to a wire rack to cool completely before assembling. This cooling step is essential for preventing a soggy cake when you add the lemon glaze.
Assemble and Glaze the Cake
While the cake layers cool, make the lemon glaze by whisking together 0.5 cup powdered sugar and the remaining 1 tablespoon lemon juice until smooth. If needed, add a splash of water to reach your desired consistency—it should be thick enough to coat the back of a spoon.
Place one cake layer on a serving plate and spread a thin layer of the reserved apple mixture on top. This step adds extra flavor and moisture to each slice. Place the second layer on top and gently press down.
Brush the top and sides of the cake with the lemon glaze, letting any excess drip down the sides. The glaze adds a bright citrus note that cuts through the sweetness of the apples. Let the glaze set for 10 minutes before serving to give it time to firm up slightly.
Pro Tips For Making Apple Cake Recipe Low Fat
- WHISK EGGS TO STIFF PEAKS: I learned this the hard way—whipping egg whites for this cake isn’t just about soft peaks. Push them to stiff peaks (the beak should stand straight up when you lift the whisk), or the cake will sink like a rock. The light brown sugar’s moisture fights against structure, so don’t skimp on the beating.
- MEASURE APPLESAUCE COLD: Straight from the jar? Nope. Chill that applesauce for 30 minutes first—it thickens slightly and behaves better in the batter. I used to ignore this, and the cake always turned out denser than it should’ve. Cold applesauce also keeps the egg whites from deflating when folded in.
- DON’T OVERMIX THE DRY INGREDIENTS: One wrong turn with the mixer and you’ll end up with a tough, chewy cake instead of a tender one. Sift the flour and sugars together, then just mix until combined—no streaks, but no overworking either. The egg whites are doing the heavy lifting here, so don’t sabotage them.
- BAKE UNTIL 200°F INTERNAL: That cake might look done at 190°F, but resist the urge to pull it out. Wait for the center to hit 200°F—the applesauce keeps things moist, so it needs that extra time to set properly. I’ve pulled cakes too soon, and they’d either collapse later or stay gummy. A toothpick check? Good. A thermometer? Better.
Essential equipment for this dish
Mixing Essentials
Start with a stand mixer fitted with the whisk attachment—this is my go-to for beating egg whites to stiff peaks. I love the KitchenAid Artisan Series for its consistent performance, but any quality mixer with a timer will work. If you're mixing by hand, use a balloon whisk for maximum volume in those egg whites. 🥚
For measuring dry ingredients precisely, invest in a medium-sized sifter to avoid lumps in your flour mixture. I use a OXO Good Grips sifter—it's durable and makes quick work of combining flour, baking powder, and spices. A digital kitchen scale comes in handy if you prefer grams over cups, especially for the powdered sugar in the glaze.
Baking Tools
Two 8-inch round cake pans with removable bottoms are essential for easy release. I prefer Wilton Perfect Results pans—they're non-stick and bake evenly. Grease them thoroughly with cooking spray (like Misto) or a light layer of vegetable oil to prevent sticking, even though this is a low-fat recipe. Parchment paper circles save time and reduce cleanup.
A toothpick is your best friend for testing doneness—insert it into the center of each cake layer. If it comes out clean (with just a few moist crumbs), your cakes are ready. For even baking, rotate the pans halfway through the baking time. A wire cooling rack is a must for letting cakes cool properly before assembling.
Glaze Finishing
For the lemon glaze, a small whisk or fork works perfectly to combine powdered sugar and lemon juice. If you're feeling fancy, use a pastry brush to apply the glaze evenly—it gives a more professional finish than just pouring. I keep a small bowl (like a 2-cup ramekin) handy for mixing the glaze right on the serving plate.
A spatula helps spread the reserved apple mixture between layers without tearing the cake. For presentation, I like to dust the top with powdered sugar using a fine-mesh sieve—it adds a decorative touch while keeping the cake light. Store any leftover glaze in an airtight container in the fridge for up to 3 days.

Frequently asked questions
Can I substitute applesauce with something else if I don't have it?
Yes! If you're out of applesauce, try unsweetened pumpkin puree (same amount) or mashed banana (reduce by 2 tablespoons per cup). For a neutral flavor, prune puree works too. Just remember these swaps may slightly alter texture—pumpkin adds density while banana brings natural sweetness.
Why does my low-fat cake turn out dry?
Overmixing the batter or baking too long are the most common causes. The egg whites should be beaten to stiff peaks but not dry—if they look grainy, add 1 teaspoon water. Also, check your oven temperature with an oven thermometer (many run hot). For extra moisture, brush warm cake layers with lemon juice before glazing.
How can I make this cake even lighter?
Replace ½ cup of the all-purpose flour with almond flour for a tender crumb, or fold in ¼ cup whipped egg whites at the end. For extra lift, add ½ teaspoon cream of tartar when whipping egg whites—it stabilizes the peaks better. Chilling the batter for 30 minutes before baking also prevents sinking.
Can I bake this in a bundt pan instead?
Reduce baking time to 20-25 minutes and check for doneness early—the bundt shape cooks faster. Brush the finished cake with extra lemon glaze and dust with powdered sugar for a festive look. Just grease the pan thoroughly since this recipe is naturally less greasy than traditional versions.
What's the best way to store leftovers?
Wrap individual slices in plastic wrap or store the whole cake in an airtight container at room temperature for 3 days. For longer storage, slice and freeze portions on a tray before transferring to a bag—thaw at room temperature. The glaze may soften slightly when reheated, so add fresh glaze before serving.
