Routine lunchbox-cookie bakers
If you usually bake one batch at a time, a timer, a suitable fan mode and room for your usual tray may matter more than having a second cavity. Check the oven’s baking performance separately from its list of modes.
Who is this for?
Multi-tray batch bakers
If you prepare several trays for lunches or freezer batches, look for multi-level hot-air cooking documented for the exact model and mode. Check that your trays fit at the intended shelf positions.
Kitchen-replacement buyers
If the new oven must fit existing cabinetry, compare the installation diagram and connection instructions with your kitchen before weighing up baking features. Electrical Safety First advises having ovens fitted by a qualified electrician.
What matters when choosing?
Decide how many trays and separate dishes you need to cook at once, then check baking performance and installation requirements for the exact oven. A larger stated capacity alone does not tell you whether your trays will fit.
| Concern | What to check | Who this matters to |
|---|---|---|
| Even, repeatable baking | Check the exact fan mode and, where available, independent findings on heat distribution and temperature accuracy. Which? assesses both in its oven testing. | If I make the same cookies each week, I want batches to bake consistently without assuming the dial temperature is exact. Around 42% of consumers would put consistent baking first. |
| Batch space | Check usable shelf positions, tray fit and whether multi-level cooking applies to the mode you plan to use; check each cavity separately on a double oven. | Preparing several lunchboxes at once makes room for more trays my deciding need. Around 33% of consumers would prioritise batch capacity and shelf flexibility. |
| Fit and upkeep | Compare the installation diagram, connection requirements and cleaning system for the exact model. | When replacing an integrated oven, I need it to fit the housing and be practical to install and clean. Around 25% of consumers would make fit, connection and upkeep their primary concern. |
Buying pitfalls
-
Assuming a fan setting guarantees even cookies
A fan-mode name does not establish measured heat distribution or temperature accuracy. Which? assesses these separately in its built-in oven testing.
Look for independent results for the model where available. With a new oven, check a small first batch before changing your usual recipe.
-
Expecting both cavities in a double oven to have hot-air baking
Bosch lists 3D Hotair for the main cavity of the MBA533BB3B, while its second-cavity cooking methods are conventional heat and grills.
Read each cavity’s cooking-method list and check which one can accommodate your cookie trays.
-
Measuring only the oven’s front
The visible width cannot confirm the required cabinet cut-out or electrical connection. Installation requirements differ by model.
Compare the model’s installation diagram and connection instructions with your kitchen before ordering. Electrical Safety First advises using a qualified electrician for oven fitting.
A mismatch may mean arranging electrical work or altering the cabinet before the oven can be installed.
-
Treating a cleaning feature as proof of baking performance
AEG lists Aqua Clean on the OU5AB20CK and catalytic cleaning on the OU5CU40M; those maintenance features do not establish how accurately either oven controls temperature.
Choose a cleaning system for upkeep, and assess cookie-baking consistency using evidence about heat distribution and temperature control.
Brands to consider
AEG
Relevant when comparing a built-in single oven with a built-under fan oven; check the particular model rather than assuming their capacities or cleaning systems match.
- AEG lists true fan cooking, multi-level cooking, a timer display and a 65 L cavity for the OU5AB20CK.
- Its built-under OU5CU40M instead lists a 45 L cavity and catalytic cleaning. Confirm which format and installation specification suit your kitchen.
Bosch
Relevant if a double oven would let you bake cookies while keeping a separate cavity available for another dish.
- Bosch lists 3D Hotair in the main cavity of the Series 4 MBA533BB3B.
- The second cavity’s listed methods are conventional heat and grills; do not assume it also has a fan-baking mode.
NEFF
Relevant when a single built-in oven with a documented multi-level hot-air mode suits the available space.
- NEFF describes the B1GCC0AN0B’s CircoTherm mode as allowing baking on up to three levels.
- NEFF states that this model has no plug and requires electrical connection by an electrician; check its installation instructions before choosing it as a replacement.

Bosch Series 4 MBA533BB3B electric double oven, black
Consider this double oven if you want a separate cavity available while baking cookies. Bosch lists 3D Hotair in the main cavity, but conventional heat and grills in the second; check the housing and electrical requirements before purchase.

CDA SG121SS built-in single gas fan oven, 70 L
This single-cavity option is relevant if your kitchen is set up for a gas oven and you want fan-assisted baking. Confirm the gas connection, cabinet fit and installation requirements with the model documentation and a qualified installer.

Simfer FO60S built-in single electric fan oven, silver
Consider this single oven if one cavity suits your usual cookie batch. Check its tray fit and exact fan-mode instructions, then confirm the cabinet cut-out and electrical connection before ordering.

Candy FCI7D405X built-under electric double oven
A two-cavity choice for a below-worktop layout. Check which cavity offers the fan mode you intend to use for cookies, and confirm the exact cavity dimensions, cabinet cut-out and electrical requirements.
Common questions
Should I lower the temperature for a fan-oven cookie recipe?
If the recipe gives a conventional-oven temperature but not a fan setting, use a conversion as a starting point and check the first batch. Which?’s UK conversion table pairs 180°C conventional with 160°C fan; the result still depends on your oven and recipe.
Does a double oven give me two fan ovens?
Not necessarily: check the cooking methods for each cavity. Bosch lists 3D Hotair in the main cavity of the MBA533BB3B, while the second cavity lists conventional heat and grills.
What should I check before replacing a built-in oven?
Check the new model’s installation diagram against the cabinet aperture, then review its electrical or gas connection instructions. Electrical Safety First advises having ovens fitted by a qualified electrician; for a gas oven, confirm the connection and installation requirements with a qualified installer.
Will a cleaning system help cookies bake more evenly?
A cleaning feature is for upkeep, not evidence of even baking. AEG lists Aqua Clean on the OU5AB20CK and catalytic cleaning on the OU5CU40M; assess heat distribution and temperature control separately, and follow the chosen model’s cleaning instructions.
