If you can do a Double Crochet, you can do a Treble Crochet. It’s really not any more difficult.
Step 1: Yarn over twice (yo) and insert your hook. If you’re starting a row, you’ll usually skip that first stitch and insert the hook into the second space.
Step 2: Yo and pull a lp through. 4 lps on hook.
Step 3: Yo and pull through 2 lps. 3 lps on hook.
Step 4: Yo and pull through 2 lps. 2 lps on hook.
Step 5: Yo and pull through 2 lps. You’re done!
