Eggless Gluten-free Orange Cake

Ingredients

2¼ cups gluten free flour  = 1½  cups rice flour 粘米粉 + ¾ cup potato flour Mąka Ziemniaczana 
2 tsp baking powder
1 tsp bicarbonate of soda [known as baking soda in the States]
4 ozs unsalted butter [half a cup or 113 grams or 1 stick]

1 tin [397 g] [1½ cups or 12 fl oz] of condensed milk 

1 cup [8 fl oz] freshly squeezed orange juice
½ teaspoon orange oil or orange extract
1 oz or 30 grams of homemade orange peel - diced finely


Method

1. Grease and flour a bundt baking tin [any bundt tin > 6 cups large]. I used a 12 - 15 cups size bundt tin. 
2. Preheat your oven to 165 C - with fan switched off - if you were to use other baking tins [i.e. not Nordic Ware platinum range] then bake the cake at 175 C.
3. Sift the flour and raising agents and mix the finely diced orange peel into the flour and set aside.
4. Squeeze 3 thin skin oranges to obtain > 1 cup [8 fl oz] of juice - you need some excess juice to make the glaze for the cake.
5. Partially melt the butter in a microwave oven [about 20 seconds or so] and mix it with the condensed milk with a spoon - I use a small silicon spoon - and then mix in the orange oil or extract.
6. Pour the condensed mix / butter mixture into the sifted flour mixture and fold with a spoon.
7. Slowly add the the orange juice in three batches into the flour milk butter mixture and fold the cake batter until one gets a smooth homogeneous mixture without any lumps.
8. Pour the cake mixture into the prepared baking tin and bake on the bottom shelf of a preheated 165 C oven for 45 minutes or until the cake is cooked. 

You can turn the skin of the oranges into homemade orange peel and store these in your freezer for future use.

Use the excess orange juice [2 tbsp + 1 tsp = 20 ml] to mix with 130 grams of sifted icing sugar for the glaze.  For a thin glaze, then add about a teaspoon of liquid glucose into the glaze.

Any excess glaze can be whipped with double cream and be served with the cake.  Whip 300 ml [half a pint] of double cream with the excess glaze until soft peaks.  Serve this with a slice of the cake.
