Then mix like this

1. Place butter into bowl. Melt 3 minutes / 70C / Speed 2.
2. Add remaining ingredients. Speed 4 / 30 seconds or until well combined.
3. Place mixture into a large piping bag. Pipe mixture into the machine or tin. I find this much easier than spooning in.
4. The machine takes 5-8 minutes to cook. if cooking in an oven it will be approximately 15 -18 minutes at 180 degrees. This depends on the size of the tin of course.
5. Combine the glaze ingredients in a small bowl and whisk until smooth. You want to consistency of pancake batter. You want it to run off the donut but leaving a nice coating behind.
6. Dip the donut into the glaze to coat all sides.
7. Place onto a wire rack and allow the glaze to set.
