Hi PaNik
My favourite recipe on Food.com to make as cupcakes is
Orange and Almond Cake (Gluten Free).
The recipe posted is for one large cake, but I like to bake as cupcakes and they are very rich and moist. You can also add in some chopped dark chocolate as a variation.
My next favourite cupcake is made from another of my finds here on the site. I love this recipe as a large cake and made into cupcakes as well. It's so easy and moist and nobody would guess it is gluten-free. Top with your favourite icing or dust with icing sugar
One Bowl Gluten Free Chocolate Cake
I've never times either cakes as cupcakes.....just baked at the required temperature and checked for doneness sooner
For ordering on-line, many of the US gluten-free chefs on this site seem to order from Amazon or Bob's Red Mill. Maybe someone else can give you some more good options
I do think to bake gluten-free that you will probably require - xanthan or guar gum, either a blended purchased flour or some of the following flours/starches
cornstarch, potato starch, tapioca starch
fine rice flour or a fine brown rice flour
sorghum flour (you might also get this at an Indian grocer labelled as 'jowar atta' or jowar flour''
millet flour
buckwheat
besan/chickpea/gram flour or other legume/bean flour
ground nuts/nut meals - such as almond meal or hazelnut meal (these sometimes are also referred to as nut flours)
arrowroot
soy flour (I'm not a fan of soy flour)
quinoa flour
gluten-free baking powder
