Expert Baking Tips for this no bake blueberry mousse tart

Although the recipe for this simple vegan chocolate tart is super easy, here are just a few expert tips i’d recommend:

  • Ensure your dates are relatively soft before blending, if your dates are tough soak them in water for around 1/2 hr then drain and add to the rest of the ingredients.
  • Cashew paste works really well here, it’s essentially the same as using soaked cashews but the process is a lot faster. So I would highly recommend it. But if you cant get your hands on any make sure to soak your cashews overnight (around hrs) then drain and blend with the rest of the tart filling ingredients.
  • Make sure to drain your tofu to remove any excess water, as any added extra liquid will ruin the consistency of the tart.

Transfer the mousse filling onto the biscuit layer and smooth it out so it’s level. To achieve the spiral design on top you will need a cake turntable and offset spatula/butter knife/spoon. Starting from the outside work your way into the center of the tart by simultaneously spinning the turntable slowly and moving your chosen utensil around the tart.
