Regular small-batch cookie baker
If you often bake one tray of oat cookies, an explicitly listed convection mode, temperature control and flexible shelf placement may matter more to you than maximum capacity.
For regular small-batch oat-cookie baking, choose a countertop oven that explicitly lists convection or fan-assisted baking, then check that its tray fits and its temperature controls cover your recipe. A multi-function air-fryer oven may suit you if you also want other cooking modes, while a compact conventional oven is an alternative when worktop space matters more than a stated fan mode. Capacity in litres alone does not tell you how much usable tray space you will have.
If you often bake one tray of oat cookies, an explicitly listed convection mode, temperature control and flexible shelf placement may matter more to you than maximum capacity.
If a full-size oven is impractical, a smaller conventional mini oven may be an option, provided both the appliance and a usable baking tray fit your space.
If you want to bake cookies and also air fry, grill or make toast, check that the oven has a Bake setting and that its tray suits your usual batch.
Decide whether a stated fan mode is essential to you, then check tray fit, recipe controls and which other functions you would actually use.
| Concern | What to check | Who this matters to |
|---|---|---|
| Fan-assisted baking | Look for an explicitly listed convection or fan-assisted mode and a temperature range covering your recipe. | I bake cookies regularly and want a stated fan mode rather than assuming one comes with a mini oven. Around 31% of consumers would put that need first. |
| Oven and tray fit | Measure your worktop and intended tray; confirm usable rack dimensions and placement clearance. | If my worktop is tight, I need room for both the oven and a practical cookie tray. Roughly 31% of consumers would make physical fit their primary concern. |
| Other cooking uses | Check for the modes you will use alongside Bake, and read the conditions behind any energy claim. | I want to bake cookies as well as air fry or grill, but a frozen-food comparison will not settle my cookie-baking choice. About 23% of consumers would prioritise multi-function use and energy-use questions. |
| Everyday handling | Check the timer, controls, cleaning instructions and the manual’s guidance on hot surfaces. | For frequent small batches, I want straightforward controls and manageable cleaning without overlooking hot doors and walls. Around 15% of consumers would put day-to-day handling first. |
A capacity of 12L, 19L or 20L does not establish the usable rack width and depth for your cookie tray.
Measure the tray you intend to use, then confirm the oven’s internal rack dimensions, supplied tray size and required worktop clearance.
Russell Hobbs UK’s energy comparison for the 26680 uses frozen French fries under stated conditions; it does not establish the electricity used to bake oat cookies.
Check what food and cooking conditions any comparison covers before using it to assess your own baking routine.
Tefal UK lists convection for the Optimo OF445840. De'Longhi UK lists Bake and upper-and-lower-element heating for the EO12012 without listing a fan mode.
If fan-assisted baking is essential, confirm that function in the specification for the exact model you plan to buy.
Tefal UK lists the 19L Optimo OF445840 with convection, a baking mode, six cooking heights and a maximum temperature of 240°C.
Russell Hobbs UK lists the 20L 26680 with Air Fry, Bake, Grill, Toast and Keep Warm settings, a 1500W rating and oven accessories.
De'Longhi UK lists the EO12012 as a 12L conventional mini oven with Bake and Grill functions and a 100–220°C thermostat range.
This air-fryer oven is a countertop choice to consider if you want to bake small batches and use other cooking functions. Check the space available for your cookie tray before deciding.

Consider this model if you want a Bake setting and hot-air convection alongside other countertop cooking functions; confirm that your intended cookie tray fits and your recipe temperature can be selected.
Check for the baking mode you want, a temperature range covering your recipe and usable rack or tray dimensions. If fan-assisted baking is important to you, look for an explicitly stated convection or fan mode rather than relying on the oven’s litre capacity.
No; start with your recipe and the appliance instructions. Tefal’s guidance says a fan-assisted oven can require a lower temperature and longer baking time depending on the food, so check your first batch before adjusting later ones.
You cannot infer that from an energy claim based on another food. Russell Hobbs UK’s stated saving for the 26680 compares cooking 400g of frozen French fries with a conventional oven at 213°C; it does not establish the energy used for your oat-cookie recipe.
Follow the manual for your exact model, including its placement and electrical instructions. For the Tefal Optimo model, the manufacturer calls for a stable surface, a fully unwound cord and an earthed socket, and warns that the door and walls become hot during use.
