Super Spongy Hot Milk Cake is a classic, tender sponge cake made with a simple but special technique: hot milk and melted butter are added to the batter just before baking. The result is an incredibly soft, fluffy cake with a delicate crumb and rich vanilla flavor.
This homemade cake is perfect for afternoon tea, birthdays, family gatherings, or simply enjoying with a cup of coffee. It requires basic pantry ingredients and doesn’t need frosting to taste delicious. A light dusting of powdered sugar is all you need, although you can easily dress it up with whipped cream, fresh fruit, or your favorite frosting.
ngredients
- 1 3/4 cups all-purpose flour
- 2 teaspoons baking powder
- 1/4 teaspoon salt
- 4 large eggs, room temperature
- 1 1/2 cups granulated sugar
- 2 teaspoons vanilla extract
- 1 cup whole milk
- 6 tablespoons unsalted butter
- 1/4 cup vegetable oil
- Powdered sugar, for dusting, optional
Equipment
- 9-inch round or 9×9-inch square cake pan
- Large mixing bowl
- Medium saucepan
- Electric hand mixer or stand mixer
- Whisk
- Rubber spatula
- Wire cooling rack
Instructions
1. Prepare the Oven and Pan
Preheat your oven to 350°F (175°C).
Grease a 9-inch round cake pan or 9×9-inch square baking pan with butter or nonstick cooking spray. Line the bottom with parchment paper, leaving a little paper extending over the sides if desired.
Greasing and lining the pan makes it much easier to remove the delicate sponge cake after baking.
2. Combine the Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking powder, and salt.
Set the mixture aside.
For an especially light cake, sift the flour mixture once or twice. Sifting removes lumps and helps distribute the baking powder evenly throughout the flour.
3. Beat the Eggs and Sugar
Place the eggs in a large mixing bowl. Add the granulated sugar.
Using an electric mixer, beat the eggs and sugar on medium-high speed for approximately 5–7 minutes.
The mixture should become very pale, thick, and fluffy. When you lift the beaters, the mixture should fall in a thick ribbon that remains visible on the surface for a few seconds.
This step is important because the beaten eggs provide much of the cake’s airy structure.
Add the vanilla extract and mix briefly.
4. Heat the Milk and Butter
While the eggs are beating, place the milk and butter in a medium saucepan.
Heat over medium-low heat until the milk is hot and the butter has completely melted. Do not allow the mixture to boil.
Remove the saucepan from the heat and stir in the vegetable oil.
The milk mixture should be hot when added to the batter, but it should not be aggressively boiling.
5. Fold in the Flour
Gradually add the dry ingredients to the beaten egg mixture.
Using a rubber spatula, gently fold the flour into the eggs. Work carefully and avoid vigorous stirring, as overmixing can deflate the air you created while beating the eggs.
Add the flour in two or three additions, folding just until no large streaks of flour remain.
6. Add the Hot Milk
Slowly pour the hot milk and butter mixture into the batter while gently folding.
Do not pour everything in at once and stir vigorously. Instead, add it gradually and fold carefully until the batter is smooth and evenly combined.
The batter will become slightly thinner after the hot milk is incorporated. This is completely normal.
The combination of hot milk, butter, and oil gives the cake its exceptionally moist and tender texture.
7. Pour Into the Pan
Pour the batter into the prepared cake pan.
Gently tap the pan once or twice on the countertop to release any large air bubbles. Avoid excessive tapping because you don’t want to lose the air incorporated into the eggs.
Place the pan on the center rack of the preheated oven.
8. Bake the Cake
Bake for approximately 35–45 minutes, depending on your pan and oven.
The cake should rise beautifully and develop a light golden-brown surface.
To check for doneness, gently press the center with your fingertip. It should spring back rather than remain indented.
You can also insert a wooden toothpick into the center. If it comes out clean or with a few moist crumbs, the cake is ready.
Avoid opening the oven during the first 25–30 minutes because a sudden drop in temperature can cause the cake to collapse.
9. Cool
Remove the cake from the oven and let it cool in the pan for about 10 minutes.
Run a thin knife carefully around the edges, then turn the cake out onto a wire rack.
Remove the parchment paper and allow the cake to cool completely.
Once cooled, dust the top with powdered sugar if desired.
Tips for the Softest, Spongiest Cake
Use room-temperature eggs. They whip more efficiently and help create greater volume.
Beat the eggs long enough. The egg-and-sugar mixture should be thick, pale, and fluffy. Underbeaten eggs can produce a dense cake.
Keep the milk hot. Warm milk helps the butter melt and blends smoothly into the batter. However, avoid boiling it.
Fold gently. The trapped air from the whipped eggs is essential for the cake’s structure.
Don’t overbake. Even a few extra minutes can dry out a sponge cake. Start checking toward the end of the recommended baking time.
Use fresh baking powder. Old or inactive baking powder can prevent the cake from rising properly.
Serving Suggestions
This cake is wonderful served simply with powdered sugar and a cup of tea or coffee.
For a more indulgent dessert, top individual slices with whipped cream and fresh strawberries, blueberries, raspberries, peaches, or mangoes.
You can also drizzle the cake with chocolate sauce, caramel sauce, or a simple vanilla glaze. For birthdays and celebrations, slice the cooled cake in half horizontally and fill it with whipped cream and fruit.
Storage
Store the cooled cake in an airtight container at room temperature for up to 3 days.
For longer storage, refrigerate it for up to 5 days. Allow refrigerated slices to come to room temperature before serving for the softest texture.
The cake can also be frozen. Wrap individual slices tightly in plastic wrap, place them in a freezer-safe bag or container, and freeze for up to 2 months. Thaw at room temperature before serving.
