Ingredients
Scale
1 3/4 cups (220g) all-purpose flour
3/4 cup (75g) unsweetened cocoa powder
1 1/2 tsp baking powder
1/2 tsp baking soda
1 tsp fine salt
1 cup (200g) granulated sugar
1/2 cup (100g) packed light brown sugar
3 large eggs, room temperature
3/4 cup (180ml) neutral oil (vegetable or canola)
1 cup (240g) sour cream or Greek yogurt
1/2 cup (120ml) whole milk (or non-dairy)
2 tsp vanilla extract
1 oz (about 1 tbsp) instant coffee granules dissolved in 1 tbsp hot water (optional)
3/4 cup (135g) chocolate chips or chopped chocolate
1/2 cup chopped roasted peanuts or walnuts
1/2 cup peanut butter or dulce de leche
Coarse sugar or flaky sea salt, for sprinkling (optional)
Instructions
Preheat the oven to 350°F (175°C). Grease a 9-inch (23cm) round cake pan or springform and line the bottom with parchment for easy removal.
In a large bowl, whisk together flour, cocoa, baking powder, baking soda, and salt until evenly combined and airy.
In a separate bowl, whisk the granulated and brown sugars with the eggs until glossy and slightly thickened, about 1–2 minutes. Add oil, sour cream, milk, vanilla, and the dissolved coffee; whisk until silky and smooth.
Pour the wet ingredients into the dry and fold gently with a spatula until just combined. If the batter is too thick, add a splash more milk (1 tbsp at a time).
Fold in the chocolate chips and half the chopped nuts. Spoon the batter into the prepared pan, smoothing the top but leaving it slightly uneven.
Warm the peanut butter (or dulce de leche) for 10–15 seconds so it’s spoonable. Drop tablespoons of the peanut butter over the batter, then use a skewer or knife to swirl—don’t overmix; visible ribbons are the goal.
Sprinkle the remaining nuts over the top and a pinch of coarse sugar or flaky salt if using. Bake for 35–45 minutes, rotating halfway, until the top is set, cracked, and springs back lightly when touched. A toothpick should come out with a few moist crumbs.
Cool in the pan on a wire rack for 20–30 minutes, then run a knife around the edge and release the cake. Serve warm for a gooey center or cool completely for cleaner slices.
Optional finish: drizzle melted chocolate or a quick salted caramel over the top, then sprinkle a little flaky salt. Slice with a sharp knife wiped between cuts for neat pieces.
Notes
Chaos Cake is a forgiving, one-bowl chocolate cake with fudgy pockets, a crunchy top, and ribbons of peanut butter or dulce de leche—easy to make, adaptable, and perfect for sharing.
