Ingredients for angel food cake made with splenda
Twelve egg whites, a splash of lemon, and Splenda—just the basics for this magical cake.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Egg Whites 🥚 | 12 whole | Room temperature for best volume |
| Granulated Splenda 🍬 | 1 ½ cups | 1:1 sugar substitute, no bulking agent |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for light texture |
| Unsalted Butter 🧈 | ¼ cup | Melted, cooled slightly |
| Pure Vanilla Extract 🌿 | 1 tbsp | High-quality, no alcohol aftertaste |
| Cream of Tartar 🧂 | ½ tsp | Stabilizes egg whites |
| Salt 🧂 | ¼ tsp | Fine sea salt preferred |
| Cake Flour 🌾 | ½ cup | Optional for extra tenderness |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Unflavored Gelatin 💧 | 2 tsp | Bloomed in 3 tbsp warm water |
| Aluminum or Nonstick Tube Pan 🍰 | 1 whole | 10-inch size recommended |
Egg whites are non-negotiable here. Room temperature is key—they whip up faster and hold more air. I grab mine from the fridge an hour before baking. Trader Joe's sells them pre-separated, which saves time. For Splenda, stick with the granulated version—the brown sugar substitute won’t dissolve properly. The cake flour is optional but makes a noticeable difference in tenderness. If you skip it, add an extra 0.25 cup of all-purpose flour. Always sift your flour—clumps kill that signature lightness.
No cream of tartar? Substitute with 0.25 tsp lemon juice, but your whites won’t stabilize as well. Fresh lemon juice is better than bottled—ReaLemon is my go-to for convenience. Want extra vanilla flavor? Add 0.5 tsp vanilla bean paste alongside the extract. The gelatin might seem odd, but it’s what gives angel food cake its signature bounce. Unflavored Knox gelatin works best—no weird aftertastes. For the butter, don’t use margarine; it won’t melt evenly and can make the cake greasy.
This cake is best served the day it’s made—it actually gets better as it sits. Store it in an airtight container at room temperature for up to 3 days. For longer storage, slice and freeze portions for 1 month. The tube pan is your best friend—no need to flip it mid-bake. Just let it cool upside down for 10 minutes before unmolding. Serve with fresh berries or a dollop of whipped coconut cream for a vegan-friendly topping.
Why You'll Love This Recipe
- No Mixer Needed: I swear by this trick—folding the egg whites into the dry ingredients by hand gives that signature fluffy texture without a machine. The secret’s in the splenda: it dissolves smoothly, so no clumps to fight, and the flour just needs a quick sift. Honestly, my stand mixer stays parked for this one.
- Sweet Without Guilt: That vanilla extract? It’s the star. A single teaspoon cuts through the sweetness so cleanly, you’ll forget it’s sugar-free. The butter in the frosting (yes, I add a thin layer) makes it rich but not heavy—like a cloud with a hug.
- Bakes in a Flash: Set it and forget it. Thirty minutes in the oven, no peeking, no fuss. I’ve made this for birthday cakes, potlucks, and even as a last-minute dessert when company drops by. The tube pan makes it effortless to slice and serve—no leftovers sitting in the fridge for days.
- Budget-Friendly Luxury: Egg whites are cheap, splenda stretches further than sugar, and a stick of butter goes a long way. Between us, this recipe feeds six for under $5, and the leftovers? They disappear faster than you can say “second slice.” My kids think it’s a treat, but my wallet’s happy too.
Step-by-step instructions for angel food cake made with Splenda
Here's how to create that signature light-as-air texture using Splenda instead of sugar.
Prepare the Tube Pan and Bloom the Gelatin
Preheat your oven to 350°F and grease the inside of the tube pan thoroughly with unsalted butter, using a paper towel to wipe away any excess. This ensures the cake won't stick to the sides. While the oven heats, bloom the 2 teaspoons unflavored gelatin in 3 tablespoons warm water (not hot) by sprinkling the gelatin over the water and letting it sit for 5 minutes until fully dissolved.
I always use this method because the gelatin adds subtle body to the cake without affecting the light texture. If you skip blooming the gelatin properly, it won't dissolve completely and could create graininess in your cake. Keep this mixture at room temperature until you're ready to use it.
Whip the Egg Whites to Stiff Peaks
In a large, spotless mixing bowl, combine the 12 whole large egg whites, 0.5 teaspoon cream of tartar, and 0.25 teaspoon salt. Beat on medium speed until soft peaks form, then increase to high speed and continue beating until the egg whites form stiff, glossy peaks that hold their shape when you lift the beaters. This should take about 5-7 minutes.
This step is crucial for that signature angel food cake texture. I like to tilt the bowl slightly while beating to ensure the egg whites incorporate evenly. If you see any liquid pooling at the bottom, gently fold it back in—this keeps the structure consistent throughout. The egg whites should be thick enough to hold their shape but still slightly shiny, not dry or crumbly.
Gradually Add Splenda and Flour
With the mixer still running on low speed, gradually add the 1.5 cups granulated Splenda and 1.5 cups all-purpose flour (sifted together) in three equal additions. After each addition, increase the speed to medium and beat for 1 minute to fully incorporate. Be careful not to overmix—just until the batter is smooth and fully combined.
Here's the thing—adding the Splenda and flour gradually prevents the batter from deflating. I always sift the flour first to avoid lumps, which can create dense pockets in the cake. After mixing, the batter should be thick but still pourable. If it looks too stiff, you can gently fold it with a spatula to restore some air.
Fold in Butter, Vanilla, Lemon Juice, and Gelatin
In a separate bowl, melt the 0.25 cup unsalted butter and cool it slightly. Then, stir in the 1 tablespoon pure vanilla extract, 1 tablespoon lemon juice, and the bloomed gelatin mixture. Gently fold this mixture into the egg white batter in three additions, using a spatula to cut through the center and fold from the bottom up. Be careful not to deflate the batter.
The lemon juice brightens the flavor while the gelatin adds subtle structure. Folding gently is key here—you want to maintain as much air as possible. If the batter starts to look curdled or grainy, don't worry; it should smooth out as you fold. The final batter should be thick but still hold some air pockets.
Bake and Cool the Cake
Spoon the batter into the prepared tube pan, smoothing the top with a spatula. Bake in the preheated 350°F oven for 45-50 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean. Rotate the pan halfway through baking for even cooking.
I always check for doneness by looking for a golden top and testing with a toothpick. If the toothpick comes out with a few moist crumbs but no wet batter, it's done. Let the cake cool in the pan for 10 minutes, then invert it onto a wire rack to cool completely. This cooling process is essential—rushing it can cause the cake to collapse.
Add Cake Flour for Extra Tenderness (Optional)
While the cake cools, sift the 0.5 cup cake flour over the top of the inverted cake. Gently press it into the surface with your fingers. This optional step adds a tender, velvety texture to the top layer. If you skip it, the cake will still be delicious—it just won't have that extra luxurious finish.
This step is purely for texture lovers. The cake flour creates a fine, powdery coating that gives the cake a more refined look and feel. Once fully cooled, you can slice and serve. The cake should be light, airy, and perfectly sweetened with Splenda—no dense or heavy texture here!
Pro Tips For Making Angel Food Cake Made With Splenda
- Whip Egg Whites Cold: Pull the bowl of egg whites out of the fridge right before beating—cold whites whip faster and hold more air. I used to skip this, and my cakes always ended up dense; now they’re light as a cloud. Use a clean, grease-free bowl (even a hint of fat kills volume), and beat on medium-high until stiff peaks form.
- Sift Splenda Twice: Splenda clumps like a stubborn guest at a party. Sift it into the dry ingredients twice—first with the flour, then again after mixing—to ensure even distribution. Uneven sweetness means some bites taste like cake, others like sugar-free regret.
- Butter the Pan Wrong: Don’t just swipe butter around the tube pan—use a pastry brush to coat the entire inside, including the bottom. A thin, even layer prevents sticking, and the butter adds a subtle richness that vanilla alone can’t match. (Yes, even for angel food cake.)
- Bake Until Cool: The cake will keep rising after you pull it from the oven—sometimes by an inch. Let it cool in the pan for 10 minutes, then flip it out immediately onto a wire rack. Waiting longer traps steam, turning your airy cake into a sad, dense brick.
Best sauces and condiments for angel food cake made with splenda
Classic Whipped Cream
This is my go-to topping for angel food cake—simple, light, and perfectly sweetened. Whip 1 cup heavy whipping cream with 2 tablespoons powdered Splenda and ½ teaspoon vanilla extract until soft peaks form.
For extra flair, fold in 1 tablespoon crushed freeze-dried raspberries or toasted coconut flakes. The Splenda keeps the cream sweet without overpowering the cake’s delicate flavor. 🥛
Berry Compote
Fresh berries feel too messy, so I make a quick compote using 1 cup mixed berries (strawberries, blueberries, raspberries), 1 tablespoon Splenda, and 1 teaspoon lemon juice. Simmer for 5 minutes until the berries break down slightly, then strain for a smooth sauce.
Drizzle over slices or spoon alongside for a burst of fruity brightness. This works especially well with the cake’s vanilla notes.
Chocolate Ganache
For chocolate lovers, a dark chocolate ganache elevates this cake to dessert showstopper status. Melt 6 ounces dark chocolate (70% cocoa) with ¼ cup heavy cream and 1 tablespoon Splenda, then cool until thickened but still pourable.
Drizzle over slices or pipe decorative swirls. The bitterness of dark chocolate contrasts beautifully with the cake’s sweetness, and Splenda keeps it from being too heavy.
Caramel Drizzle
Warm ½ cup caramel sauce (store-bought or homemade) with 1 teaspoon Splenda to thin slightly, then drizzle over cake slices. For a gourmet touch, add ¼ teaspoon sea salt to enhance the caramel’s sweetness.
The salty-sweet combo balances the cake’s lightness perfectly. I like to pair this with a dollop of whipped cream for extra indulgence.
Citrus Glaze
Brighten the cake with a zesty glaze made from ½ cup powdered Splenda, 2 tablespoons lemon juice, and 1 tablespoon water. Whisk until smooth, then drizzle over cooled slices.
The acidity cuts through the richness, making each bite feel fresh. For extra flair, add 1 teaspoon grated lemon zest to the glaze before drizzling.
Coconut Whipped Cream
For a tropical twist, substitute regular whipped cream with coconut whipped cream. Whip 1 cup coconut cream (chilled overnight) with 2 tablespoons Splenda and ½ teaspoon vanilla extract** until fluffy.
Top slices with toasted coconut flakes for a vacation-worthy dessert. This works especially well if you’re avoiding dairy or want a lighter option.

Frequently asked questions
Can I substitute Splenda with another sweetener in this recipe?
While Splenda works perfectly here, you can use erythritol or monk fruit sweetener in a 1:1 ratio. Avoid honey or maple syrup—they add moisture that can make the cake dense. If using powdered sweeteners, sift them to prevent graininess. The key is maintaining the cake's light texture, so liquid sweeteners won't work.
Why does my angel food cake sink in the middle?
This usually happens from overmixing the batter or opening the oven door too early. The egg whites need to set properly at 350°F for 45-50 minutes without interruption. Also, ensure your tube pan is properly greased and the cake cools completely upside down on a wire rack. If it sinks slightly after cooling, it's normal—just slice from the top!
How do I make this cake vegan?
Replace egg whites with 12 tablespoons aquafaba (chickpea brine) whipped to stiff peaks using 0.5 tsp cream of tartar and 0.25 tsp salt. Use vegan butter for greasing and replace gelatin with 2 tsp agar-agar dissolved in 3 tbsp water. The texture will be slightly different but still light. For best results, bake at 325°F for 55-60 minutes.
Can I bake this cake in a bundt pan instead?
Yes, but expect a denser texture since bundt pans don't allow for the same dramatic rise. Grease it thoroughly and reduce baking time to 35-40 minutes. For best results, use a tube pan—it's designed for angel food cake's signature height. If using a bundt pan, check for doneness at 30 minutes as they cook faster.
Why does my cake taste bitter?
This usually means the egg whites weren't whipped enough or you used too much cream of tartar. The batter should be glossy and hold stiff peaks. Also check your Splenda—using the brown sugar version can add bitterness. For flavor balance, add 0.5 tsp vanilla bean paste or a pinch of salt to enhance sweetness. Always use fresh egg whites for best results.
