Sweet and salty marmite doughnuts

Preheat oven to 180ºC fan bake and lightly spray a 8 hole doughnut pan with cooking oil spray.

In a large bowl, stir flours, sugar, baking powder and cinnamon together.

Place oat milk, margarine and Marmite in a microwave-safe bowl. Microwave on medium-heat until margarine has just melted (the mixture should be warm rather than hot). Whisk together, then add egg and vanilla essence and whisk again.

Pour liquid mixture into dry ingredients and fold in until just combined.

Transfer mixture to a large piping bag and pipe into the donut pan until donut cups are 2/3 - 3/4 full. Bake for 10-12 minutes, until doughnuts are cooked through. Leave to cool for a couple of minutes before transferring to a wire cooling rack.

Make glaze. Stir brown sugar and water together in a small saucepan on low heat, until sugar has dissolved. Add margarine and Marmite and whisk until well combined. Remove from heat. Sift in icing sugar and stir until smooth.

Dip the tops of the doughnuts into the glaze. Return to the cooling rack and leave to set before serving.
