Steps

1. Lightly grease the inside of the rice cooker pot with vegetable oil and spread evenly with a paper towel.
   🕒 01:44
2. Place 100g of chocolate in a heatproof bowl and chop as finely as possible.
   🕒 02:06
3. Add 150ml of milk to the chopped chocolate, cover with plastic wrap, and microwave on 600W for 1 minute.
   🕒 02:27
4. After microwaving, stir well to melt the chocolate. If there are still lumps, microwave for another 30 seconds on 600W and stir well. (Key Point!) Make sure to melt completely to avoid large chunks.
   🕒 02:51
5. Add 15g of unsalted butter, cut into small pieces, to the melted chocolate mixture and stir well until melted. (Key Point!) If the butter doesn't melt, microwave for a short time.
   🕒 03:33
6. Once the butter has melted, crack in 1 egg and mix well with a whisk until there are no lumps of egg white remaining.
   🕒 03:59
7. Sift in 100g of pancake mix and 2 tbsp of cocoa powder, and mix well with a whisk to prevent lumps. (Key Point!) Pancake mix is relatively easy to mix without lumps, but mixing thoroughly will result in a smooth batter.
   🕒 04:16
8. Pour the batter into the greased rice cooker pot and drop it from a height 2-3 times to remove large air bubbles.
   🕒 04:50
9. Set the rice cooker and select the normal cooking mode. (Key Point!) Cooking times vary by rice cooker model, so be sure to use a timer. Note that it may finish faster than the indicated time.
   🕒 05:05
10. After the first cooking cycle is complete, insert a bamboo skewer into the center to check. If raw batter sticks, cook again in normal mode.
    🕒 05:55
11. If the rice cooker pot is too hot to press the button for re-cooking, wait for it to cool down before starting the normal cooking cycle again.
    🕒 06:19
12. After 15 minutes of the second cooking cycle, pause and insert a bamboo skewer. If no raw batter sticks, it's done. (Key Point!) I cooked for a total of 60 minutes this time, but if it's still raw, cook for an additional 10-20 minutes.
    🕒 06:53
13. Once cooked, invert the cake from the rice cooker pot onto a plate or board.
    🕒 07:23
14. Once it has cooled down slightly, cut into your desired size and enjoy.
