Baked, cakey cinnamon donuts covered with Biscoff icing.
Set your oven to 180°C/350°F (160°C/325°F for fan or convection ovens) and make sure you have two 6-hole silicone donut pans to hand.
In a large bowl, mix the flour, baking powder, cinnamon and sugar together.
Add the melted margarine to the bowl along with the soy milk and vanilla extract. Mix well until smooth.
Divide the mixture into the donut pan holes (you'll get around 10).
Bake for around 20-25 minutes, until golden brown on top and a toothpick comes out clean. Wait until they are completely cool before removing them from the donut pan.
Prepare the icing by mixing the Biscoff spread, soy milk and icing sugar together. Spread this onto the donuts once they are completely cooled.
Top each donut with a Biscoff biscuit if desired. (Do not add until you are ready to serve, they will go soggy otherwise.)
