blueberry upside-down cake

I like berries. All sorts of berries – raspberries, strawberries, gooseberries, blackberries, blueberries..

I think it is because they are sweet, yet at the same time there is tartness. I adore things that are slightly sour.

And also because they are great to bake with!

There are times when a recipe calls out strongly to me. BAKE ME! BAKE ME! It would shout. Many times, that recipe would contain some form of berries, or chocolate, or both.

What I like about baking with berries, apart from the flavour and moistness they impart to the cake, is that I can usually substitute one type of berries with another.

I buy berries when they are on sale. After all, I live in Singapore and we import most of our fruit and vegetables. Berries can be very expensive. When they are on sale, I buy loads and freeze them.

My favourite berry to bake with has to be blueberries. I simply love the colour of blueberries. 

As with most cakes, I started by creaming the butter with the sugar. 

Until it became light and fluffy.

Then I added the eggs one at a time, beating each egg thoroughly before adding the next one.

Then the orange zest and vanilla extract were added, and mixed into the batter.

What you would end up with is a batter that looked like it had curdled. But all is okay.

The flour and buttermilk were then added in the sequence: flour-buttermilk-flour-buttermilk-flour. Beat well after each addition.

The resulting batter should be smooth.

The blueberries were placed in a single layer in a springform tin that had been greased, lined with baking paper and dusted with flour. Sugar was scattered over the blueberries.

The batter was poured over the blueberries, and using a spatula, I smoothed the top.

Once baked, the cake was left to cool in the springform pan for about 15-20 minutes before I removed the ring and peeled off the baking paper.

The cake was dusted with icing sugar and left to cool.

I dusted the cake with more icing sugar before serving it. But that is totally optional. 🙂
