Common Questions
Is this the official Hershey’s recipe?
It is Hershey’s-style and inspired by the classic “Perfectly Chocolate” proportions and method. The big idea is the same: a cocoa cake with a thin batter and a hot liquid to bloom the cocoa. I also use oil for an extra-tender crumb and a slightly upgraded buttercream ratio for better coverage.
Do I have to use coffee?
No, but it helps. Coffee does not make the cake taste like coffee, it makes it taste more chocolatey. If you prefer, use boiling water. Either way, make sure it is genuinely hot so the cocoa blooms.
Why is the batter so thin?
That is normal. The hot liquid loosens the batter and blooms the cocoa, and the cake bakes up moist instead of dense. Pour carefully and trust the process.
How do I know it is done?
A toothpick should come out with a few moist crumbs. The tops should also spring back when lightly pressed. If you like numbers, aim for about 200 to 205°F in the center.
Can I bake this in a 9x13 pan?
Yes. Grease and line if you can. Bake at 350°F for about 30 to 40 minutes, start checking at 30. A toothpick should come out with a few moist crumbs.
Can I make cupcakes?
Absolutely. Fill liners about 2/3 full and bake at 350°F for 18 to 22 minutes.
How do I keep the cake from sticking?
Grease the pans, add parchment rounds, then lightly dust with cocoa powder (or flour). Baking spray works too. Parchment is the real insurance policy.
Is this frosting enough for the sides?
Yes. This makes enough to fill and fully frost a 2-layer 9-inch cake with a cozy, classic coating. If you want thick swoops or tall piped borders, bump it up by 1/2 batch.
My frosting looks grainy. What happened?
Usually it is either powdered sugar not fully mixed or the butter was too cool. Beat longer, and if needed add 1 to 2 teaspoons warm milk and keep mixing until glossy.
Any high altitude tips?
If you are baking above about 3,500 feet, you may need small tweaks. Start by reducing sugar by 1 to 2 tablespoons, increasing flour by 1 to 2 tablespoons, and slightly reducing baking powder (about 1/4 teaspoon). Also watch the bake time, cakes can finish faster up high.
