- Why did the center sink?
- You likely opened the oven door too early or used too much baking powder. The sudden temperature drop or over-leavening causes the structure to collapse before it sets.
Moist Rum & Espresso Chocolate Cake
Think of this as the love child of tiramisu and a rich, fudge chocolate cake. The espresso deepens the cocoa profile without making it taste like coffee, while the rum relaxes the crumb for an incredibly tender texture. It's not a dry sponge; it's a buttery, moist cake that stays fresh for days.

Instructions
1
✓
Whisk together the dry ingredients (flour, sugar, cocoa, baking powder) in a large bowl.
Tip: Sift the cocoa powder to avoid bitter lumps in your batter.
2
✓
In a separate bowl, mix the melted butter, milk, coffee, rum, and egg yolks. Pour this wet mixture into the dry ingredients.
Tip: The acidity of the coffee reacts with the baking powder, helping the cake rise.
3
✓
Beat the egg whites until stiff peaks form. Gently fold them into the chocolate batter using a spatula.
Tip: The egg whites provide aeration. Fold gently—don't stir vigorously—to keep those air bubbles intact.
4
✓
Bake at 350°F (180°C) for 35-40 minutes. Test with a toothpick.
Tip: The cake is done when a toothpick inserted comes out with just a few moist crumbs, not wet batter. If it's bone dry, it might be overbaked.
5
✓
Let cool completely, dust with powdered sugar, and serve with freshly whipped cream.
Tip: The rich cream balances the deep cocoa flavor perfectly.
