How long does it usually take for prep and baking? me and two friends are using it for a school project and would love to know?wn

Recipes usually specify durations for known processes - holding in fridge, freezer or at room temp for a batter to rise, mix flavors or cool down.
If not specified, cool down usually takes about an hour.
For unknown processes - like assembling ingredients or mixing raw ingredients together - you can estimate average 15 minutes.
These times will vary depending on complexity of ingredients, cook's level of knowledge and specific recipe, but that 15 minutes figure is a good rough starting point.
Read through the recipe, add up the times and you have a rough estimate of total duration.
If you want to be safe (or generous) add 20% to that rough estimate to give yourselves a total work time.
Good luck with make this!
