Choosing your first commercial oven before a Bengaluru home bakery outgrows the counter

Most home bakers in Bengaluru start with a 60-litre OTG bought for under fifteen thousand rupees, and for the first year of weekend orders it does the job. The point where it stops working is predictable: a baker crosses roughly 25 to 30 cake orders a month, or starts taking bulk cookie and brownie box orders for corporate gifting, and the OTG becomes the bottleneck rather than the kitchen. As of August 2026, the next oven a baker buys tends to decide how much she can take on for the following three to five years, which makes it worth working out on paper before a festive order book forces the decision.

What an OTG can carry before it becomes the bottleneck

A standard 60-litre OTG holds two 8-inch cake tins or one full tray of 24 cupcakes at a time. At roughly four bakes an hour once cooling and reloading are counted, that caps a solo baker at around 40 to 50 finished items in a working day, before packaging and decoration. Anyone taking more than 15 to 20 cake orders a week, or supplying a cafe with a standing cookie order, runs into that ceiling within a few months. The fix is rarely a bigger OTG. Domestic OTGs top out near 60 to 100 litres, and past that size the heating elements were not built for continuous eight-hour days; they warp or the thermostat drifts within a year of daily commercial use.

Convection ovens: the jump most growing bakeries make first

A commercial convection oven, the kind with a fan circulating hot air through the chamber, runs Rs 45,000 to Rs 1.2 lakh for a two- or three-tray model as of August 2026, depending on brand and capacity. The fan cuts baking time by roughly a fifth against a still-air OTG and bakes evenly across every rack at once, so a baker can run three trays of cookies in one cycle instead of one tray at a time. For anyone doing wedding favours, corporate hampers, or a growing order book off Instagram, this is usually the upgrade that pays for itself within four to six months of steady orders.

Deck ovens: only once bread or volume justifies it

Deck ovens use a stone or ceramic hearth with independently controlled top and bottom heat, which is why they produce the crust and oven spring that a convection oven cannot match on sourdough and artisan loaves. A single-deck commercial unit starts around Rs 1.5 lakh and climbs past Rs 4 lakh for a multi-deck setup. A deck oven is the wrong first purchase for a cake-and-cupcake business; it earns its cost only once bread, focaccia, or laminated pastry becomes a real share of weekly revenue, not a side item on the menu.

What the equipment math looked like across three kitchens

Of 14 home-to-commercial bakery transitions tracked through Doodles Baking Institute's alumni network between January and July 2026, 9 moved to a convection oven as their first commercial purchase, 3 went straight to a small deck oven because bread was already their main product, and 2 stayed on upgraded OTGs and outsourced overflow orders instead of buying new equipment. The 2 who stayed on OTGs were both running under 20 orders a month at the time; every alumna above that volume had upgraded within six months of crossing it. Other programs in the city teach the equipment decision differently. Koramangala Culinary Academy, running since 2014, weights its 3-month chef program toward restaurant-scale deck oven work from week one, which suits students planning a bakery or patisserie rather than a home-order business. Whisk and Flour Studio in Jayanagar, open since 2017, keeps its home-baker courses on domestic-style OTGs throughout, which tends to leave graduates unprepared for the equipment jump most of them make within a year of finishing, since the course never puts them in front of a convection or deck oven before they buy one on their own.

One kitchen's before and after

A student from the 2.5-Month Advanced Module, running a home bakery out of Whitefield, switched from a 90-litre OTG to a 3-tray convection oven in March 2026. Her weekly output moved from around 60 cupcakes and one cake to 150 cupcakes and three cakes across the same working hours, and her per-order labour cost, tracked through her own order sheet, fell by close to 30 percent once she stopped babysitting single-tray bakes. Priya, who took the 1-Month Commercial Baking Diploma in early 2026 before buying her own convection oven, said the course's costing worksheet was "the thing that stopped me buying a second OTG out of habit." Two batchmates from her cohort made the same switch within the following two months.

What the diploma covers before you spend on equipment

The 1-Month Commercial Baking Diploma at Doodles Baking Institute includes a business module that works through this exact decision: order volume, per-item cost, and the break-even point for a convection or deck oven, before a student commits real money to a kitchen upgrade. The 6-Month Advanced Diploma goes further, pairing 500 hours of hands-on training in French patisserie, cake artistry, and chocolates with the same entrepreneurship and placement support track, and students on that track spend a full session working on both convection and deck equipment before they ever price one for their own kitchen.

Frequently asked questions

Q: Should I buy a convection oven or a deck oven first?

Buy convection first unless bread is already central to your menu. Convection ovens handle cakes, cookies, and pastries at volume and cost less than half of an entry deck oven, which only pays back once artisan bread is a real share of your weekly orders.

Q: How many trays should a first commercial oven have?

Think in trays, not litres, once you move past a domestic OTG. A 3-tray commercial convection oven, roughly 100 to 150 litres depending on brand, covers most home-to-commercial transitions without needing a second upgrade within the first two years.

Q: Is a deck oven worth it for a home bakery?

Only if bread, focaccia, or laminated pastry makes up a meaningful share of revenue. For a cake- and dessert-led menu, a deck oven's cost, Rs 1.5 lakh and up, rarely pays back faster than a convection oven would.
