Sweet date paste cake with rich, caramelized jujube filling is a nourishing treat. A family recipe with naturally sweet, fresh date flavor.
Preheat the oven to 350°F (175°C). Line an 8-inch loaf pan with parchment paper and lightly grease the sides for easy removal.
In a saucepan over medium heat, combine pitted dates and milk. Simmer gently for 8–10 minutes, stirring often, until dates are soft and most milk is absorbed. Mash into a smooth paste with a fork or immersion blender. Cool for 10 minutes.
In a mixing bowl, whisk together the flour, baking powder, salt, and cinnamon to evenly distribute the leavening agent and spices.
In a separate large bowl, cream the soft butter and date paste together with a spatula, ensuring a cohesive, airy texture. Beat in eggs one at a time, then add vanilla extract, blending until the batter is smooth and glossy.
Fold the dry ingredients gently into the wet mixture with a spatula, stirring minimally until just combined to avoid overmixing. Pour batter into the prepared pan and level the top.
Bake at 350°F for 35–40 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs. Allow the cake to cool in the pan for 15 minutes before transferring to a rack.
