Recipe Costing Software

Been a bread baker and pastry chef for about 5 years now. Really want my own shop. FWIW, I'm leaning towards a high end donut shop. Basically, classic pastry in donut form. All scratch made, good ingredients, no commercial ingredients, etc.

Anyway, in the business plan writing stage and I would like to have my first 20 to 30 donuts costed out. Any one have any good, simple costing software ideas? Something simple, intuitive and hopefully allow me to export data sets to excel, etc.

Gracias.
