3 tablespoons sugar
2 tablespoons cocoa powder
1 1/4 teaspoons cornstarch
1/3 cup skim milk
1/2 teaspoon vanilla

Equipment Needed

8- or 9-inch round cake pan
Mixing bowls (small, medium, and large)
Electric mixer
Whisk
Small saucepan
Wire rack
Serrated knife
Serving platter

Instructions

Preheat your oven to 350 degrees F (175 degrees C).
Lightly grease or spray an 8- or 9-inch round cake pan with non-stick cooking spray. This will ensure the cake releases easily after baking.
In a small bowl, mix together the flour, baking powder, and salt. This ensures even distribution of the leavening agent for a consistent rise.
In a medium bowl, beat the egg whites at medium speed until frothy.
Gradually add 1/4 cup of the sugar, beating until stiff peaks form. Be careful not to overbeat. Stiff peaks are crucial for a light and airy cake.
In a large bowl, using the same beaters, beat the remaining 1/4 cup of sugar and the vegetable oil spread until light and fluffy. This creaming process incorporates air, contributing to the cake’s tender texture.
With the mixer on low speed, alternately beat in the flour mixture and the skim milk until just blended. Start and end with the flour mixture to prevent gluten development.
Stir in the vanilla extract and 1/3 of the egg white mixture.
Fold in the remaining egg whites until no white streaks remain. Gently folding preserves the air in the egg whites, keeping the cake light.
Pour the batter into the prepared cake pan and bake for 35 minutes, or until a toothpick inserted in the center comes out clean. Avoid opening the oven door too frequently during baking to prevent temperature fluctuations.
Cool the cake in the pan on a wire rack for 10 minutes before inverting it onto the rack to cool completely. This prevents the cake from sticking to the pan and allows it to cool evenly.
While the cake is baking, prepare the filling and the glaze. This saves time and streamlines the process.
Filling: Prepare the instant vanilla pudding according to package directions, using the 1 1/2 cups of skim milk.
Refrigerate the filling for 30 minutes, or until thickened. Chilling allows the pudding to set properly and develop a richer consistency.
Glaze: In a small saucepan, mix together the sugar, cocoa powder, and cornstarch.
Stir in the skim milk and bring to a boil over medium heat.
Cook for 1 minute, stirring constantly, or until slightly thickened. Stirring prevents scorching and ensures a smooth glaze.
Refrigerate the glaze for 20 minutes to cool. This will help the glaze to set properly when applied to the cake.
To Assemble the Cake: With a serrated knife, carefully cut the cake in half horizontally. A serrated knife will prevent tearing and create a clean cut.
Place the bottom layer, cut side up, on a serving platter.
Spread the filling evenly over the top of the bottom layer.
Top with the remaining layer of cake, cut side down.
Spread the glaze over the top of the cake, letting some of the glaze drip down the sides for an elegant presentation.
Chill the assembled cake for at least 3 hours or until the glaze has set. Chilling allows the flavors to meld and the cake to become more cohesive.

Expert Tips & Tricks

For an extra-light cake, sift the flour before measuring.
Ensure the egg whites are at room temperature for optimal volume when beaten.
If you don’t have vegetable oil spread, unsweetened applesauce can be used as a substitute, although it may slightly alter the flavor.
To prevent the bottom cake layer from becoming soggy, you can lightly brush it with melted sugar-free apricot preserves before adding the filling.
If the glaze is too thick after chilling, add a tablespoon of skim milk at a time until you reach the desired consistency.

Serving & Storage Suggestions

Serve this Low-Fat Boston Cream Pie chilled. It’s a delightful dessert on its own, but it also pairs well with a scoop of light vanilla ice cream or a side of fresh berries.

Store any leftover pie in the refrigerator, covered, for up to 3 days. The cake may become slightly moister over time. Freezing is not recommended, as it can alter the texture of the filling and glaze.

Chocolate Cake: Replace some of the flour in the cake recipe with cocoa powder for a chocolate version.

FAQs (Frequently Asked Questions)

Q: Can I make the cake ahead of time?
A: Yes, you can bake the cake a day in advance and store it tightly wrapped at room temperature or in the refrigerator.

Q: Why are my egg whites not forming stiff peaks?
A: Make sure your bowl and beaters are completely clean and free of any grease. Even a tiny bit of fat can prevent the egg whites from whipping properly. Also, ensure there are no traces of yolk in the egg whites.

Q: Can I use a different type of pudding?
A: Yes, you can experiment with other flavors of instant pudding, such as butterscotch or chocolate, for a different flavor profile.

Q: How do I prevent the cake from sticking to the pan?
A: Make sure to grease the pan thoroughly. You can also line the bottom with parchment paper for extra insurance.

Q: My glaze is too runny. What can I do?
A: If your glaze is too runny, you can try adding a little more cornstarch, about 1/4 teaspoon at a time, and cooking it over low heat until it thickens slightly.
