woocommerce variation price

Hello everyone, I’m sorry if I’m in the wrong section of the forum but I’m new. I started to build my first website in WordPress 2 weeks ago, and I’m really enjoying it. I installed this plugin WooCommerce for my cafe website.

Till now all went ok, I have created my pages and my products.
My problem is this one:
I sell Coffee so they can be sold by 2 size Regular and Large
I have created the variation for the Syrup like Caramel and Vanilla.
I’d like to put in the variation like 50 pence and I’d like that 50p will increase the price of the coffee.
Till now I have seen that I had to create different variations Coffe Regular, Coffee Large, Coffe Regual Vanilla, Coffe Regular Caramel, Coffee Large Vanilla, Coffe Large Caramel and put the price increased. In this way I need to create to many variation.
There is any plugin or different way to do so?
This WooCommerce sound more for a Shop for clothes … and the one for the restaurant or cafe aren’t a real plugin but connection to different website who will manage the store and that is not what i want.

Hope anyone can help, thanks you in advance
