If you have not got yogurt to make the buttermilk, you can easily make it another way! For this recipe, simply stir together 125ml room temperature whole milk with 1 tbsp lemon juice. Leave to sit for 15 minutes, then use in place of the yogurt/milk mixture in this recipe.
I would recommend using a gel food colour in this recipe. Gel food colours give a much stronger colour than liquid colours do, and they do not affect the flavour as much either.
When combining the wet and dry ingredients together, do not over mix. Stir only until combined, then transfer to the pan and bake.
Use cream cheese at room temperature, as it will help it mix with the other ingredients more easily.
A small whisk or fork is best to mix the glaze together, to ensure all the ingredients are well combined and smooth.
Add extra milk a few drops at a time to achieve the glaze consistency you prefer. I like my glaze quite thick, but do add more milk to make it thinner if this is your preference.
I gather any crumbs from my donut tins to sprinkle on top of the donuts. If you prefer, you can leave the glaze plain or decorate with different sprinkles instead.
