Ingredients

Dough

  • 2 cups soy milk
  • 2.5 teaspoon dry yeast 2¼ teaspoon
  • 3 tablespoon caster sugar
  • 1/4 cup vegan butter melted
  • 1/4 cup soft vegan butter to add into the dough once kneaded
  • 6 cups plain flour

Custard:

  • 0.5 cup caster sugar
  • 3 tablespoon corn flour
  • 2 tablespoon vegan custard powder
  • 2 cups plant based milk I use soy
  • 1 teaspoon vanilla extract
  • 2 tablespoon vegan butter

Jam

  • 1 cup blueberry jam

Crumble:

  • 1/2 cup flour
  • 1/4 cup caster sugar
  • 1/4 cup brown sugar
  • 1/4 cup oats
  • 1/4 cup vegan butter

Glaze: opt

  • 1/2 cup icing sugar
  • 3 teaspoon plant milk

Instructions

  • Warm the milk. Aim for a cozy 36–42°C. If it gets too hot, just let it cool a little so it is comfortable.
  • In a microwave-safe bowl or on the stove, melt the vegan butter until soft and smooth. Take a moment to enjoy the smell.
  • Add the warm milk, sugar, and active yeast to a large bowl. Set it aside and watch the magic happen as the yeast wakes up and starts to bubble. It should look foamy and alive.
  • Add the melted vegan butter and flour to the bowl. Mix with a dough hook or a wooden spoon for 5 minutes until it comes together into a lovely, soft ball.
  • Add the softened butter to the dough and knead it in until fully combined. If kneading by hand, work it on a floured surface until smooth and silky.
  • Cover the dough with a tea towel or cling wrap so it is snug and cozy. Rest in a warm place for 2 hours. When ready, it should have nearly doubled in size. Look at it grow.
  • While the dough rests, make the custard. In a medium saucepan, whisk together sugar, cornflour, custard powder, vegan milk, vanilla, and agar agar if using.
  • Heat on medium and whisk constantly until it starts to boil and becomes frothy. The foam is normal and fun.
  • Once thickened, add the vegan butter and mix until smooth. Remove from heat and cover the surface with cling wrap to keep it silky.
  • Roll out 10 dough balls and place them on a lined baking tray. Cover again and let them rest for 45 minutes. They will puff up beautifully. Press a small well into the center of each ball.
  • Scoop the custard into the little wells evenly across all 10 buns.
  • Brush the edges with vegan plant milk to help them shine.
  • Add a tablespoon of blueberry jam on top of the custard.
  • Mix the crumble ingredients in a bowl and sprinkle a generous handful on top. Crispy, sweet, and perfect.
  • Bake in the oven for 20-25 minutes until golden and irresistible.
  • Take them out and let them cool on the tray for a few minutes. You can peek now.
  • Enjoy warm and cozy. Optional: mix the glaze ingredients and drizzle on top for an extra touch of sweetness.
  • These buns will stay fresh for 2-3 days in an airtight container, but honestly, will they last that long.
