Bev's Hot Milk Sponge Cake - Light Airy Layer Cake Recipe

This hot milk sponge cake creates an exceptionally light, airy texture through the unique technique of tempering hot milk and butter into the batter. The eggs are whipped to triple their volume, creating the signature sponge structure, while the hot milk mixture adds moisture and richness. Perfect for layer cakes, sheet cakes, or as the base for Boston cream pie. The cake bakes to a golden, tender crumb that's sturdy enough for filling and frosting yet delicate enough to melt in your mouth. This versatile recipe works equally well in round pans for layered desserts or sheet pans for casual gatherings.

Tip 1

Don't skip tempering the hot milk mixture into separate batter first - this prevents the eggs from scrambling and ensures smooth incorporation.

Tip 2

Beat eggs to full triple volume for maximum height and lightness in the finished cake.

Tip 3

Watch baking time carefully as it varies significantly by pan size - 16-18 minutes for jelly roll, 30 minutes for 9-inch rounds, 40 minutes for 9x13.

FAQ

Can I make this without a stand mixer?

Hand mixer works but requires longer beating time. Beat eggs until very pale and tripled in volume before adding sugar.

What if my milk mixture gets too hot?

Let it cool slightly before tempering. It should be hot but not violently boiling when you add it to the batter.

How long does this cake keep?

Unfrosted cake keeps 2-3 days covered at room temperature or 1 week refrigerated. Freezes well for 3 months wrapped tightly.
