Preheat oven to 175 degrees celsius. Spray your mini donut pan with nonstick spray.

Sieve together flour, sugar, cocoa powder, baking soda, instant coffee and salt. Whisk to combine.

Add oil, vanilla and water and continue to whisk until smooth.

Pour into 8 mini donut pan cavities and place in the oven to bake.

Donuts take about 10-12 minutes to fully bake. Once done, remove from oven and let cool in pan for 10 minutes. After 10 minutes, release donuts onto a cooling rack and let cool completely.

Prepare frosting.

Whisk together icing sugar, water and melted Nuttelex. Whisk till smooth.

Add cocoa powder and vanilla and continue to whisk until creamy and well combined.

If donuts are not yet cool, cover icing with a damp tea towel to prevent it from drying out.

Once donuts are cool, dip them into the frosting to cover the tops. Sprinkle with anything you fancy!
