Spurs Ladies were quickly out of the blocks as they kicked-off their FA Women's Cup campaign in style.
It took just seven minutes for Kirsten Thompson and Jess Cheeseman to set-up Emma Kayser for the opener as they stormed into a 4-0 half-time lead.
Miranda Hall provided the ammunition for the second and third goals, converted by Sam Pittuck after 15 and 30 minutes.
Now in total control, Jess hit a piledriver from fully 30 yards into the top corner for the fourth just before the break.
Miranda's fine work down the left was rewarded with an excellent individual goal for 5-0 before Ebony Heath released Emma Sherwood for the sixth. Wendy Martin completed the scoring.
"You never know what can happen in a cup game and Denham were not taken lightly," added Karen.
"We scored some excellent goals and they had trouble living with us.
"We will look to build on that result and try to get a positive result at Millwall after we disappointly lost to them in the league in December."
