Eggless applesauce cake is a simple square snack cake with cinnamon and a stir-together batter. Unsweetened applesauce provides moisture, while baking soda and vinegar help the batter rise without eggs.
Heat oven to 350°F (175°C). Grease an 8-inch square pan and line its base with parchment. Whisk flour, brown sugar, baking soda, cinnamon and salt in a large bowl, breaking up sugar lumps.
Whisk applesauce, oil, milk, vinegar and vanilla in a separate jug. Pour into the dry mixture and fold gently just until no flour pockets remain.
Spread evenly in the pan. Bake 30–35 minutes until a toothpick inserted near the center comes out without wet batter and the center springs back lightly.
Cool in the pan for 20 minutes before cutting into nine squares. Do not judge the crumb while it is piping hot, when the applesauce moisture can make it look gummy.
