Minitoc Chapter and Title on Same Line and Centered. Center TOC, also

I didn't fully solve this. But I was able to get the Chapter Number and Chapter Title on the same line. Here's a MWE for it:

documentclass[11pt,oneside]{book} % [text size]{document type}
usepackage[utf8]{inputenc}
usepackage{graphicx}
usepackage{fancyhdr, blindtext} %for testing
usepackage{minitoc} % Get chapter level TOC
usepackage{titlesec}
renewcommand{mtctitle}{TABLE OF CONTENTS}
dominitoc
setcounter{parttocdepth}{4} % set minitoc sublevel
setcounter{secnumdepth}{4} % to get X.X.X.X
mtcsetrules{*}{off}
titleformat{chapter} {largebfseries}{CHAPTER thechapter}{0em}{---}
titleformat{section} {normalfontbfseries}{thesection}{0em}{---}
titleformat{subsection} {normalfontbfseries}{thesubsection}{0em}{---}
titleformat{subsubsection}{normalfontnormalsizebfseries}{thesubsubsection}{0em}{---}

And that gets this done:
