I found the recipe online:
This is my first crumb cake. And It turned out to be a big success. I did a little change based on the original recipe.
Sugar 80g ( I’m afraid the original recipe would be very sweet, so I reduced the sugar)
Baking powder 1tsp
Vanilla extract 1/2tsp
For topping :
Biscuit mix is used in original recipe. I changed it. I used flour and ground almond powder instead. I reduced butter and sugar too. Cos my husband is on a diet.
Ground almond powder 20g
Cinnamon powder 1 tsp
1. Cream butter and sugar.
2. Beat egg and milk, mix with butter.
3. Add flour and baking powder to the butter mixture. Then add in vanilla extract.
4. Pour batter into pan.
5. For topping: put all the topping ingredients in a bowl. Rub them by hand. And they will become crumb.
6. Sprinkle crumb topping over batter in the pan.
7. Preheat oven to 180 degree C. Bake for 30 mins. ( you can check with a toothpick. Poke the cake with toothpick, if it comes out clean, then the cake is done).
Powdered sugar is used to top the cake when cool. I didn’t use it.
The topping is very crunchy.
