Sour Cream - Blueberry Crumb Cake

"Sour cream and lots of butter make the cake tender and moist and offset the bold, tangy flavor of gleaming fresh, juicy blueberries. A crunchy cinnamon-infused crumb topping cloaks the cake, adding a buttery caramel flavour"

And yes, as described by Tish Boyle, these cakes had a crunchy top and they were really moist and tender. A quite unusual combination but they were quite welcomed by us... hehehehe...

I had replaced the sour cream with low fat yoghurt as my yoghurt was expiring soon, and this also explained why I had attempted this bake... Oopsie...hehehehe... I had also reduced the sugar level if you do not wish your cake to be too sweet like me.

Yeilds a 9-inch square cake

Ingredients:

Crumb Topping

121g all purpose flour

50g caster sugar

80g firmly packed dark brown sugar

1 tsp ground cinnamon
1/8 tsp salt

100g unsalted butter, melted

Sour Cream Blueberry Cake

181g all purpose flour

1 1/4 tsp baking powder

1/4 tsp baking soda

1/4 tsp salt

142g fresh or unthawed frozen blueberries

242g sour cream

1 1/2 tsp vanilla extract

142 unsalted butter, softened

200g sugar

2 large eggs

1. Position a rack in the center of the oven and preheat the oven to 175C. Butter and flour the bottom and sides of a 9 inch square baking pan.

2. In a medium bowl, whisk together the flour, baking powder, baking soda and salt until well blended.

3. In another bowl, toss the blueberries with 1 tbsp of flour mixture until the berries are coated; set aside. In a small bowl, whisk together the sour cream and vanilla extract; set aside.

4. In the bowl of an electric mixer, using the paddle attachment, beat together the butter and sugar at medium speed until light and fluffy, 4 to 5 minutes. Beat in the eggs one at a time, beating well after each addition and scraping down the side of the bowl as neccessary. At low speed, beat in the flour mixture in three additions, alternating it with the sour cream in two additions. Using a rubber spatula, fold in the blueberries. Scrape the batter into the prepared pand and smooth the top with a spatula.

Sprinkle the crumb topping evenly over the batter, breaking up any large lumps with your fingers.

5. Bake the cake until a toothpick inserted into the center comes out clean, about 45 minutes. Place the cake in the pan on a wire rack and cool completely.

6. Cut the cake into squares and serve from the pan.
