I believe the next major operation on the Western front was the Allies' Operation Market Garden. The idea was to get across the Rhine in force using paratroopers followed up with armor, and thus hopefully win the war before Winter set in.
This was a failure for the Allies, as they got themselves stretched a bit too far, and couldn't complete their main objectives. So it could be viewed as a German success (although a defensive one). But even after this victory, the Germans were on the defensive.
Part of what allowed the initial German success in the Battle of the Bulge was that the Allies had it in their heads that they were on the offensive, and there weren't going to be any more German offensives.
Thus the Ardennes Offensive (aka: The Battle of the Bulge) can be viewed as the German's first attempt to take back the offensive.
Model and von Rundstedt both ... felt that maintaining a purely
defensive posture (as had been the case since Normandy) would only
delay defeat, not avert it. They thus developed alternative, less
ambitious plans that did not aim to cross the Meuse River ... plan
called for a classic blitzkrieg attack through the weakly defended
Ardennes Mountains—mirroring the successful German offensive there
during the Battle of France in 1940—aimed at splitting the armies
along the U.S.—British lines and capturing Antwerp.
