Notes
Ingredient Notes and Shopping Tips
Coca-Cola: For best results, use regular, not zero-sugar or diet soda.
Flour: Measure your flour by spooning it into your measuring cup. Then level with a knife.
Cocoa Powder: I used Hershey Unsweetened Natural Cocoa Powder. Avoid Dutch Processed Cocoa, which requires an acidic ingredient like baking powder to rise.
Eggs: Bring eggs to room temperature to ensure everything comes together smoothly. I just set them on the counter for 30-60 minutes before baking.
Tips
Easy Cleanup: Line your pan with nonstick foil or parchment paper to ensure it doesn't stick.
Don't overmix: Mix just until the flour just disappears. Overmixing leads to a tough, dense cake.
Don't Overbake: Cake is done when a toothpick inserted in the center comes out clean. It is okay if it has a few moist crumbs.
Add Frosting While Cake Is Warm: It sets up quickly. Pour over while it's still warm so melts into the cake.
