For the Cake:

  • 1½ cups self-rising flour
  • 1 tsp baking powder
  • ¼ tsp baking soda
  • ¾ cup sugar
  • 1½ cups dairy-free milk + 2 tsp apple cider vinegar
  • ⅓ cup dairy-free yogurt
  • ⅓ cup olive oil
  • 1 cup blueberries (tossed in a little flour)

For the Crumb Topping:

  • ½ cup brown sugar
  • ½ cup all-purpose flour
  • ¼ cup butter

Preheat the Oven:

  1. Preheat your oven to 340°F (170°C).
  2. Grease a cake tin.

Prepare the Wet Ingredients:

  1. Mix the dairy-free milk with the apple cider vinegar and set aside to thicken and curdle.
  2. Stir in the dairy-free yogurt and olive oil until well combined.

Combine the Dry Ingredients:

  1. Sift the self-rising flour, baking powder, baking soda, and sugar into the wet mixture.
  2. Gently mix everything together until just combined, being careful not to overmix.

Add the Blueberries:

  1. Fold the flour-coated blueberries into the batter.

Pour into the Tin:

  1. Pour the batter into the prepared cake tin.

Make the Crumb Topping:

  1. In a separate bowl, rub the butter into the flour and brown sugar until it forms a crumbly mixture.
  2. Sprinkle the crumb topping evenly over the cake batter.

Bake the Cake:

  1. Bake for 40-50 minutes, or until the cake is well-risen and a toothpick inserted into the center comes out clean.
  2. If the top starts to brown too much, cover the cake with tin foil halfway through baking.
