Revenue at Patisserie Holdings, chaired by serial entrepreneur Luke Johnson, rose 13.3% to £104.1m in the year to 30 September.
Pre-tax profits rose 18.2% to £17.2m as Patisserie hailed the success of its afternoon teas, of which it sold 133,000 over the year.
But Johnson flagged "uncertain economic conditions" as he vowed to control costs.
"We have achieved growth in revenues and profits despite uncertain economic conditions and, for the first time, we have exceeded revenues of £100m - a significant achievement.
"We will continue to control costs and manage our supply chain in this period of macro-economic uncertainty; thus I am confident of another successful year of growth," he said.
The company added that its biggest cost pressure is the National Living Wage, with the firm introducing a new staff rostering method to mitigate the impact.
Patisserie Holdings, which also operates Druckers, Baker & Spice and Philpotts, opened 21 new stores in the period and now has 184 overall.
