Baking your first cake in an OTG is easier than it looks. The key is getting the preheating, temperature and tray placement right. This step-by-step guide walks you through baking a soft, evenly cooked cake in an OTG oven, with a handy temperature chart and troubleshooting tips for common problems.
What You Need
- An OTG with top and bottom heating (both elements on for baking).
- A metal or aluminium cake tin that fits inside the oven.
- Your cake batter, ready to pour.
- Oven mitts and a wire rack for cooling.
Step 1: Preheat the OTG
Set the OTG to 180°C with both top and bottom rods on, and preheat for 10 minutes. Preheating is essential — putting batter into a cold oven leads to a dense, unevenly risen cake.
Step 2: Prepare the Tin
Grease the tin with butter or oil and dust lightly with flour, or line it with parchment paper. Pour in the batter, filling no more than two-thirds so it has room to rise.
Step 3: Place and Bake
Place the tin on the wire rack in the middle position so heat surrounds it evenly. Bake at 180°C. Use the chart below as a starting point and adjust for your oven.
| Cake Size | Temperature | Approx. Time |
|---|---|---|
| Small (6 inch) | 180°C | 25–30 min |
| Medium (7–8 inch) | 180°C | 30–40 min |
| Cupcakes/muffins | 170°C | 18–22 min |
| Large (9 inch) | 170°C | 40–50 min |
Step 4: Check Doneness
Insert a toothpick into the centre near the end of the baking time. If it comes out clean, the cake is done. If batter sticks, bake for another 5 minutes and check again. Avoid opening the door repeatedly in the first 20 minutes, as it lets heat escape and can collapse the cake.
Step 5: Cool Properly
Let the cake rest in the tin for 10 minutes, then turn it out onto a wire rack to cool fully before frosting or slicing. Cooling on a rack prevents a soggy base.

Troubleshooting Common Problems
- Cake sinks in the middle: Oven door opened too early or batter overmixed.
- Top browns too fast: Lower the rack or reduce top heat; cover loosely with foil.
- Dense, heavy cake: Under-creamed butter and sugar, or expired baking powder.
- Uneven baking: Rotate the tin halfway through and ensure proper preheating.

Frequently Asked Questions
At what temperature should I bake a cake in an OTG?
180°C with both top and bottom rods on works for most cakes. Reduce to 170°C for larger cakes that need longer baking.
Do I need to preheat the OTG?
Yes. Always preheat for about 10 minutes so the cake rises evenly from the moment it goes in.
Which rack position is best for cakes?
The middle position is best, so heat surrounds the tin evenly from top and bottom.
Can I use a glass dish to bake a cake in an OTG?
Yes, oven-safe glass or ceramic works, but metal tins conduct heat better and bake more evenly.
Why is my cake raw in the middle but cooked outside?
The temperature was likely too high. Lower it by 10°C and bake a little longer so the centre cooks through.
