Active Time: 2 minutes
Total Time: 2 minutes
Servings: 100 g (approx.)


  • 100 g plain or all-purpose flour
  • 1 level tsp baking powder - I always use a measuring teaspoon rather than one I'd use to make a cup of tea as it's much more accurate.


  • Put your ingredients (100g plain flour, 1 tsp baking powder) into a large bowl.
  • Mix together (I like to use a whisk) until the baking powder is evenly distributed in the flour.
  • Your self-raising flour is now ready to use in your chosen recipe.


This recipe will give you ever so slightly over 100g of self-raising flour (due to the weight of the baking powder). However, you shouldn't notice a difference in the results of your baking by using it as a substitute for 100g of self-raising flour.
