Packable Chocolate Chip Cake

This chocolate chip cake starts with a yellow cake mix and gets doctored into something far better than the box promises. A full cup of sour cream goes into the batter along with oil, eggs, and water, creating a dense, incredibly moist crumb that stays fresh for days, which is exactly what “packable” means.

The sour cream is the upgrade here. It replaces most of the water the box directions would call for, adding fat and acidity that make the cake tender and rich. Semi-sweet chocolate chips fold in at the end and distribute throughout the batter so every slice has melted chocolate pockets.

Bake it in a fluted tube (Bundt) pan for 45-50 minutes. The tube shape bakes the thick, heavy batter evenly from both the outside and the center. Cool it in the pan for a full 20 minutes before flipping or the cake will crack. A dusting of powdered sugar right before serving is all the decoration it needs.

Kitchen Tips

• Use a cake mix with pudding in the mix. The pudding adds extra moisture and a tighter crumb that holds up during transport.
• Beat for the full 2 minutes. That extra mixing develops structure in the batter and helps it support the weight of the chocolate chips.
• Grease the Bundt pan thoroughly, especially the fluted ridges. A stuck cake in a fluted pan is a broken cake.
• Test doneness with a toothpick. The center should come out clean or with just a few moist crumbs, not wet batter.

Variations

• Marble version: Swirl chocolate batter through the yellow by mixing a few tablespoons of cocoa into half the batter before pouring.
• Peanut butter chips: Replace half the chocolate chips with peanut butter chips for a peanut butter-chocolate combination.
