Without looking at the recipe it's hard to say if that's intentionally a wet dough or not, but yeah sometimes they're almost just soupy. Sometimes letting it sit for a while will let it get some tension as the gluten forms. Use a sifter if you're using scoop measures for flour, since going right from the bag might be more compressed (although that would probably make the dough dryer if anything), or if you have access digital scales are very useful.
This is a kneading technique for wet dough:

You can probably just let it sit for a few (2-4+) hours once the wet and dry ingredients are mixed together fully instead of kneading.
Either way, looks like it turned out tasty!
