Who is this for?

Small-batch bakers short on worktop space

You usually bake one modest tray of cookies and need both the oven and its baking tray to fit a compact kitchen.

Bakers focused on consistent browning

You care more about baking controls and being able to check the cookies as they cook than about a long list of functions. Which? includes baking results and temperature variation in its mini-oven testing.

Cooks who want more than a cookie oven

You also expect to use the appliance for tasks such as toast, roasting, reheating or air frying, and can make room for a model that serves those needs.

What matters when choosing?

Start with a Bake-capable oven and a tray that suits your usual batch. Then weigh the space it takes against the other cooking tasks you will actually use it for.

Concern What to check Who this matters to
Baking control Look for a Bake setting, a timer and a way to monitor the tray. Check whether the manual distinguishes baking from air frying. If my cookies brown quickly, I want to watch the first tray and adjust the timing rather than assume a full-size oven recipe will transfer unchanged. Roughly 31% of consumers put baking control first.
Tray and worktop fit Compare the supplied pan with your usual batch, then check exterior dimensions and the clearances required by the manual. With little counter space and only one small batch to bake, I need room for the oven without choosing a tray too small for my cookies. Around 31% of consumers make fit their main concern.
Other cooking uses Check that the model offers oven baking as well as the other functions you expect to use regularly. If the appliance will also handle everyday meals, I can make more use of additional functions and cooking space. Roughly 25% of consumers prioritise versatility beyond cookies.
Cleaning and setup Read the cleaning instructions and check removable accessories. Confirm that the intended electrical connection can accommodate the appliance. When I use an oven often, I want crumbs to be manageable and a suitable place to plug it in. Around 13% of consumers put upkeep and safe setup first.

Buying pitfalls

  • Choosing by litre capacity alone

    Capacity does not tell you how many cookies will fit on the supplied pan with space between them. Our Place lists a 25.1 cm × 22.4 cm bake pan for the Wonder Oven.

    Compare pan dimensions with your usual batch, and measure the intended worktop position against the oven’s exterior dimensions and required clearances.

  • Applying an air-fryer speed claim to cookies

    Russell Hobbs bases its published speed and energy comparison for the 26680 on frozen cheese pizza cooked at 200°C against a conventional electric oven. That comparison does not establish how peanut butter cookies will bake.

    Use the model’s baking instructions for a first small batch, watch the browning and adjust subsequent batches as needed.

  • Overloading an extension lead

    Electrical Safety First warns that exceeding the maximum current rating of an extension lead, cable reel or block adaptor can cause overheating and fire.

    Check the appliance instructions and the lead’s marked rating, including the load from anything else connected to it. Do not use a damaged plug or cable.

  • Buying more oven than one tray requires

    Extra rack space and cooking functions take up room that may not be useful if you only bake a small tray. Good Housekeeping UK also found the interior of the Ninja Foodi 10-in-1 Multifunction Oven tricky to clean.

    Consider a larger model when you will regularly use its additional cooking space or functions; otherwise, focus on a tray that fits your usual cookie batch.

Brands to consider

Our Place

The Wonder Oven is a small countertop option to consider when baking-pan dimensions and worktop fit matter more than space for several trays.

  • Our Place lists a 25.1 cm × 22.4 cm supplied bake pan for the Wonder Oven, giving you a specific surface to compare with your cookie batch.
  • A small pan may mean baking in several rounds if you need more cookies or wider spacing.

Russell Hobbs

The 26680 is a 20-litre air-fryer mini oven for shoppers who want to bake and use the same appliance for other cooking tasks.

  • Russell Hobbs lists a 20-litre capacity and provides model-specific instructions for its cooking modes.
  • Its manual says air frying differs from conventional oven cooking, so cookie timing may need adjustment.

Ninja

  • Good Housekeeping UK reported even browning and strong cooking performance in its 2026 mini-oven review.

  • Breville advertises a Bake function and adjustable temperatures up to 200°C for this model.

Frequently asked questions

Is a very small countertop oven enough for peanut butter cookies?

Yes, if it has a suitable baking function and its supplied or compatible tray gives your usual batch enough room. Compare tray dimensions rather than relying on litre capacity alone: Our Place lists a 25.1 cm × 22.4 cm bake pan for the Wonder Oven.

Should I use Air Fry or Bake for cookies?

Start with the model’s Bake guidance or a recipe written for a countertop oven. Russell Hobbs notes that air frying differs from conventional oven cooking, so check the first batch and adjust timing rather than treating the modes as interchangeable.

Can I plug a countertop oven into an extension lead?

Only use an extension lead if the appliance instructions allow the setup and the lead’s maximum current rating accommodates the combined connected load. Electrical Safety First warns that an overloaded lead, cable reel or adaptor can overheat and cause a fire.

How should I clean a countertop oven after baking?

Let the oven cool, then follow its model-specific cleaning instructions. If you also air fry in a Russell Hobbs 26680, its manufacturer instructs users to clean out the crumb tray frequently when using that setting.
