Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 30 minutes
• Total Time: 50 minutes
• Servings: 10
• Yield: 1 cake
• Dietary Type: Low Calorie

Ingredients

• 1/2 cup nonfat dry milk powder, reconstituted
• 1 cup all-purpose flour, sifted
• 1 1/2 teaspoons baking powder
• 1 dash salt
• 3 egg whites
• 1/2 cup Splenda sugar substitute
• 1/4 cup sugar
• 2 teaspoons lemon peel, grated

Ingredient Notes:

• For the nonfat dry milk, follow the package directions for reconstitution. Make sure it’s fully dissolved.
• Sifting the flour is crucial for a light cake. Don’t skip this step!
• Freshly grated lemon peel provides the best flavor. Avoid the white pith, which can be bitter.

Equipment Needed

• Small saucepan
• Sifter
• Electric mixer
• Small mixing bowl
• 9-inch angel food pan (ungreased)
• Cake tester or toothpick
• Bottle

Instructions

1. In a small saucepan, gently heat the reconstituted nonfat milk until tiny bubbles form around the edge of the pan. Be careful not to boil it. Remove from heat and set aside to cool slightly.
2. Preheat your oven to 350°F (175°C). While the oven is heating, sift together the flour, baking powder, and salt in a medium bowl. This ensures even distribution of the leavening agents and a lighter texture. Set aside the sifted dry ingredients.
3. In a small bowl of an electric mixer, using the whisk attachment, beat the egg whites at high speed until stiff peaks form. This process aerates the whites, which is essential for the sponge cake’s characteristic lightness.
4. Gradually add the Splenda sugar substitute and the sugar to the beaten egg whites, continuing to beat at high speed until the mixture is smooth, glossy, and well blended. This should take about 5 minutes. The mixture should hold its shape.
5. At low speed, carefully blend in the sifted flour mixture just until smooth. Overmixing at this stage will develop the gluten in the flour, resulting in a tougher cake. Stop mixing as soon as the flour disappears.
6. Add the slightly warmed milk and the grated lemon peel to the batter. Beat briefly, just until everything is combined. Avoid overmixing.
7. Immediately pour the batter into an ungreased 9-inch angel food pan. Do not grease the pan, as the cake needs to cling to the sides to rise properly.
8. Bake for 30 minutes, or until a cake tester (toothpick) inserted into the center comes out clean. The cake should be golden brown and spring back lightly when touched.
9. Invert the pan over the neck of a bottle (or use the built-in legs of the angel food pan, if it has them) and let the cake cool completely. This prevents the cake from collapsing and helps it maintain its airy texture. This step is crucial.
10. Once completely cooled, gently loosen the cake from the sides of the pan with a thin knife or spatula. Invert onto a serving plate. Serve plain or with a light dusting of powdered sugar (optional).

Expert Tips & Tricks

• Make sure your egg whites are at room temperature for optimal volume when beaten. A pinch of cream of tartar can also help stabilize the whites.
• To ensure the Splenda dissolves properly, you can mix it with a tablespoon of warm water before adding it to the egg whites.
• If you don’t have an angel food pan, you can use a tube pan with a removable bottom, but be sure it’s ungreased.
• Keep a close eye on the cake during baking. Ovens vary, so adjust the baking time accordingly. If the cake starts to brown too quickly, tent it with foil.
• For a more intense lemon flavor, add a few drops of lemon extract along with the lemon peel.
• If you notice your cake sinking after removing it from the oven, it may be a sign of underbaking. Next time, bake it for a few more minutes.

Serving & Storage Suggestions

This light sponge cake is delicious served plain, offering a subtle sweetness and refreshing lemon flavor. You can also enhance it with a dusting of powdered sugar, a dollop of Greek yogurt, or a handful of fresh berries. A light glaze made with lemon juice and powdered sugar is also a great option.

To store, keep the cake in an airtight container at room temperature for up to 2 days. You can also refrigerate it for up to 5 days, but it may become slightly drier. For longer storage, freeze the cake, well-wrapped, for up to 2 months. Thaw in the refrigerator before serving.

Variations & Substitutions

• Gluten-Free Sponge Cake: Substitute the all-purpose flour with a gluten-free blend. You may need to add a binding agent like xanthan gum to improve the texture.
• Citrus Variations: Experiment with different citrus flavors by using orange zest or lime zest instead of lemon.
• Spice Cake: Add a teaspoon of ground cinnamon or nutmeg to the flour mixture for a warm, spiced flavor.
• Almond Extract: Add 1/2 teaspoon of almond extract for a richer flavor.
• Dairy-Free Version: Use a dairy-free milk alternative (like almond or soy milk) for reconstituting the dry milk powder. The flavor will be slightly different, but still delicious.

FAQs (Frequently Asked Questions)

Q: Why is it important to use an ungreased angel food pan?
A: The cake batter needs to cling to the sides of the pan to rise properly. If the pan is greased, the batter will slide down, and the cake will not rise as high.

Q: Can I use regular sugar instead of Splenda?
A: Yes, you can replace Splenda with regular sugar, but keep in mind that this will increase the calorie content of the cake.

Q: Why is it important to invert the cake after baking?
A: Inverting the cake allows it to cool evenly and prevents it from collapsing. The cake clings to the sides of the pan as it cools, maintaining its airy texture.

Q: How can I tell if the cake is done?
A: Insert a cake tester or toothpick into the center of the cake. If it comes out clean or with just a few moist crumbs, the cake is done.

Q: Can I make this cake ahead of time?
A: Yes, you can bake the cake a day or two in advance. Store it in an airtight container at room temperature or in the refrigerator.
