Ingredients for angel food cake made with splenda
Twelve egg whites and a few clever tricks make this angel food cake light as air—no refined sugar needed.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Egg Whites 🥚 | 12 whole | Room temperature, no yolks |
| Splenda Granulated Sweetener 🍬 | 1 ½ cups | Measured accurately, not packed |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for light texture |
| Cream of Tartar 🧂 | 1 ½ tsp | Stabilizes egg whites |
| Unsalted Butter 🧈 | ¼ tsp | For greasing tube pan |
| Vanilla Extract 🍃 | 1 tsp | Pure vanilla preferred |
| Salt 🧂 | ¼ tsp | Fine sea salt |
| Fresh Blueberries 🫐 | 1 cup | Optional for filling |
| Powdered Sugar 🍬 | ½ cup | For dusting (optional) |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
The egg whites are everything here—room temperature is non-negotiable. Grab a 12-count carton from the dairy aisle (not the store-brand stuff). Cream of tartar is your secret weapon—it stabilizes the whites like magic. Splenda measures like sugar, but pack it loosely or you'll end up with a dense cake. For the flour, King Arthur or Gold Medal brands work best—they're finely milled and consistent. If your store doesn't carry Splenda, Swerve or monk fruit sweetener are solid backups, though they might need slight adjustments in baking time.
No cream of tartar? Substitute 1.5 tsp lemon juice or white vinegar—it's the same acid magic. Fresh blueberries are optional but make this feel special—frozen works in a pinch, just toss them in a colander to drain. Want extra fluff? Add 1 tbsp cornstarch to the flour for even more stability. The vanilla extract should say 'pure' on the bottle—imitation vanilla has a weird aftertaste. And that 0.25 tsp butter? Use it to grease the pan—don't skip this, or your cake will stick like glue.
This cake is best served immediately after baking, but if you must wait, store it loosely wrapped at room temperature for up to 2 days. It reheats beautifully—30 seconds in the microwave brings back that fresh-from-oven fluff. For the powdered sugar dusting, sift it through a fine-mesh strainer to avoid clumps. The blueberries? Toss them in 1 tbsp sugar before folding—they'll keep the cake moist for days. Leftovers? Slice and freeze for up to 3 months—thaw at room temp before serving.

Step-by-step instructions for angel food cake made with Splenda
Here's how to create a perfectly light angel food cake using Splenda for a sweet, sugar-free treat.
Prepare Your Tools and Ingredients
Start by separating the 12 whole large egg whites into a completely clean, grease-free mixing bowl. Any trace of fat will prevent proper whipping. Place this bowl in your refrigerator for 15 minutes to chill—this helps stabilize the egg whites for better volume.
While the bowl chills, prepare your tube pan by coating it lightly with the 0.25 teaspoon unsalted butter using a pastry brush. Then dust it thoroughly with all-purpose flour, tapping out any excess. This ensures easy removal later. Preheat your oven to 350°F and position the rack in the center position.
Whip the Egg Whites to Stiff Peaks
Remove the chilled bowl from the refrigerator and add the 1.5 teaspoons cream of tartar and 0.25 teaspoon salt. Using an electric mixer, beat on high speed until soft peaks form. This usually takes about 2-3 minutes—you'll see the egg whites thicken and hold their shape when the beaters are lifted.
Gradually add the 1.5 cups Splenda Granulated Sweetener while continuing to beat. This step is crucial—adding the sweetener too quickly can cause the egg whites to deflate. Beat for another 3-5 minutes until the mixture forms stiff, glossy peaks that stand straight up when the beaters are lifted. The bowl should feel cool to the touch.
Fold in the Dry Ingredients
In a separate bowl, sift together the 1.5 cups all-purpose flour and gently fold it into the egg white mixture using a spatula. Work quickly but carefully to maintain as much air as possible—this is what creates that signature light texture. Add the 1 teaspoon vanilla extract and mix just until combined.
For the blueberry filling (optional), toss the 1 cup fresh blueberries with the 1 tablespoon lemon juice to prevent them from turning dark. Drain any excess liquid before using. You'll want to fold these into the cake batter after it's been poured into the pan.
Bake and Cool the Cake
Pour the batter into your prepared tube pan, smoothing the top with a spatula. If using blueberries, gently press them into the top layer of batter. Bake in the preheated 350°F oven for 35-40 minutes or until the top is golden brown and the cake springs back when lightly touched.
Remove from the oven and let the cake cool in the pan for 10 minutes. Then carefully invert it onto a wire rack to cool completely. This cooling process is essential—it allows the cake to set properly and develop that perfect light, airy texture. Once fully cooled, you can dust with the 0.5 cup powdered sugar if desired.
Pro Tips For Making Angel Food Cake Made With Splenda
- Whisk Egg Whites Cold: The bowl and beaters should be ice-cold before you start—yes, even if you’re in a hurry. I learned this the hard way when my whites turned grainy after 5 minutes of beating. Pop them in the freezer for 10 minutes first, then wipe the bowl dry with a paper towel. No shortcut here—wet surfaces kill volume.
- Sift Splenda Twice: Splenda clumps like crazy, and clumps sink straight to the bottom of your batter. Sift it through a fine-mesh sieve before measuring, then sift it again right into the dry ingredients. That second pass blends it evenly, so you don’t end up with a cake that’s sweet in spots and bland in others.
- Fold in Butter Last: Add the unsalted butter after you’ve folded in the flour—this keeps the cake light, not dense. Melt it first (just until it turns to liquid, no browning), then drizzle it in while folding. Any earlier, and you’ll deflate those happy little air pockets you worked so hard to create.
- Bake Until Skeletonized: Don’t pull it out when the top looks set—wait until the edges pull away completely and the center springs back when you press it. I used to take it out too soon, and the middle stayed gummy. A toothpick test helps, but the real tell is when the cake looks like a birdcage frame. Let it cool upside down for 15 minutes first, or it’ll collapse.
Flavor customization for this angel food cake made with splenda
Classic Vanilla Twist
Start with the original recipe's 1 teaspoon vanilla extract, but elevate it by adding ½ teaspoon almond extract for depth. The nutty warmth complements the Splenda's sweetness beautifully. For an extra touch, fold in 1 tablespoon lemon zest with the flour—it brightens the flavor without overpowering. 💛
Citrus Burst Variations
Swap the vanilla for 1 teaspoon orange extract and zest for a zesty twist. The citrus pairs perfectly with Splenda's sweetness while adding a refreshing tang. For a tropical vibe, add ½ cup diced pineapple to the batter—it caramelizes slightly during baking and keeps the cake moist.
Spiced Chai Infusion
Warm up your cake with ½ teaspoon ground cinnamon, ¼ teaspoon ground cardamom, and ¼ teaspoon ground ginger folded into the flour. Add 1 teaspoon chai tea concentrate (simmered and cooled) to the batter for a cozy spiced flavor.
This works especially well with a dusting of powdered cinnamon on top.
Coffee Lover's Edge
For a mocha-inspired cake, dissolve 1 tablespoon instant espresso powder in 1 tablespoon hot water and let it cool before folding it into the batter. Add ½ teaspoon cocoa powder to the flour for depth.
This version pairs perfectly with a dollop of whipped coffee cream or a sprinkle of dark chocolate shavings.
Coconut Dream Version
Replace ½ cup of the flour with ½ cup toasted coconut flour for a tropical flavor. Add ¼ cup shredded coconut to the batter and top with toasted coconut flakes after baking. The natural sweetness of coconut enhances the Splenda while adding a delightful texture contrast.
Berry Bliss Fillings
While the original recipe includes blueberries, experiment with raspberries (tossed in 1 tbsp sugar) or strawberries (lightly macerated with 1 tsp lemon juice). For a decadent twist, fold in ¼ cup mascarpone cheese with the berries—it adds a creamy surprise in every bite. 🍓

Frequently asked questions
Why does Splenda work in angel food cake?
Splenda's granular form mimics sugar's texture perfectly, so it dissolves evenly without clumping. The key is measuring it loosely—packing it creates dense pockets. The sweetness level matches granulated sugar 1:1, but the cake stays light because Splenda doesn't add moisture like sugar does. The acidity from cream of tartar helps balance any slight aftertaste too.
Can I use Splenda in a box mix?
Not recommended! Box mixes contain leavening agents and stabilizers designed for regular sugar. Splenda's different molecular structure can interfere with the chemical reactions, leading to a cake that's either too dense or falls apart. This recipe's one-bowl method gives you full control over the structure for perfect results.
How do I know when egg whites are perfectly whipped?
Look for stiff peaks—when you lift the beaters, the meringue should form a sharp peak that stands straight up. The bowl should feel cool to the touch, and the mixture should hold its shape when you turn the bowl upside down. If it's too soft, keep whipping—over-whipping can make it grainy. This is the secret to that signature angel food cake fluff!
Why did my cake collapse?
Most likely, the egg whites weren't whipped enough or were overmixed after folding. Also check: fat contamination (even a drop of oil can deflate whites), underbaking, or opening the oven door too early. For this recipe, bake until the top springs back when touched—it should be golden, not pale. Cooling the cake upside down helps too!
Can I make this cake ahead of time?
Yes! Wrap it loosely in plastic wrap and store at room temperature for up to 2 days. For longer storage, slice and freeze individual portions for up to 3 months. Thaw overnight in the fridge—never at room temperature. The texture stays best when served fresh, but reheating slices for 10-15 seconds in the microwave restores some of that fluffy magic.
