First mash horror story

So I decide to make my first mash a stout, and I go in with confidence high. I needed 4.75 lbs. of DME so I bought two three-pound bags. I get 1.75 lbs. out of one bag and put it in a bowl on the counter.
The mash goes very well but after recirculating and spraying I have way too much wort. So I fill up my 5 gallon brew kettle to almost the top and start my boil. I take the DME BOWL FROM THE COUNTER and add half of of it

Ahhhhhh ****...

To the wort just before the boil starts which makes it overflow all over the stove. Boil goes fine and I add the OTHER HALF OF THE DME BOWL at the end of the boil. The wort is almost coed and I look over at the sink and there is a three pound bag of DME staring at me.......I ended up heating some water and dissolving the three pounds of DME, add it to the nearly cool l wort and let it cool down again. Aerated wort into the fermenter and pitched yeast. What a nightmare. Anybody with thoughts on what I will end up getting with this if anything at all?

Beer

Then my plan worked perfectly. I almost dumped the whole batch when I saw that bad on the counter. Stupid small kitchen, or apparently not small enough that I missed a large bag of powder.

First mash?? I'm confused... DME in your mash??

Partial then. Not in with the grains.
