Preheat your oven to 350°F. Lightly grease an 8" round springform pan that's at least 2" deep.
Whisk the dry ingredients together in a medium-sized bowl. Whisk the vanilla, vinegar, vegetable oil, and water in a separate bowl.
Pour the wet ingredients into the bowl of dry ingredients, stirring until combined.
Pour the batter into the prepared springform pan. Bake for 30 to 35 minutes, until a toothpick inserted into the center comes out clean.
Cool in the pan 10 minutes, then release the side, but do not remove, the side. Once completely cool reattach the side. Add the chocolate mousse to the top, cover loosely, and chill 6 hours to overnight.
Before serving, remove sides of springform pan, top with chocolate curls and chocolate dipped strawberries.
