Get out as many small bowls as you can to put ingredients into individually. If there are a bunch of wet components that you can mix together that require whisking then do that during preparation time ie melt butter and mix into milk with eggs to be poured into dry ingredients and mixed by your child.
The process of cooking is rewarding for your child if they can do it with as little intervention from you as possible. So make their jobs achievable. Once everything is prepared your child should have the skills to with limited or no assistance
- taste the ingredient,
- pour it into the main mixing bowl,
- cut up something easy to cut with a child safe knife, safety knife
- mix together and
- pour into tin, cake moulds, spoon onto baking paper, roll into a ball and squash with a spoon.
Tip: find a recipe you don't need to whisk too much and can be successful with by just adding one at a time into a single bowl without creaming, whisking to peaks or rubbing together until it resembles bread crumbs.
