Brownie maker Savannah Roqaa, who set up her baking business from her small apartment kitchen in Roundhay just last year, will be hosting the event at The Beulah in Farnley.
The 24-year-old will be outside the popular bistro in Tong Road from 11.00am on Saturday, April 17, selling her mouth-watering range of brownies.
Savannah announced the event on Instagram, saying that when the brownies have sold out at the pop-up she will update her Instagram story.
The baker will be accepting card payments at this pop-up.
Savannah's post said: "We're popping up on Saturday outside The Beulah Bistro and Deli 91 Leeds.
"We will be there from 11.00am and accept card.
"Social distancing applies.
"See you there!"
The Savvy Baker has gone from selling 30 boxes of brownies a week during lockdown to selling 1,000 in just 90 minutes at her first pop up a few months ago.
She has more than 39,000 followers on Instagram with full-time staff working around the clock to keep up with demand and celebrity clients such as Leeds and England player Kalvin Phillips.
Previous creations by The Savvy Baker include Mars Bar brookies, cookie bars stuffed with White Oreo dairy milk, gooey Rolo brownies and white Twix brownies.
The brownies do not cater towards allergies.
