Blueberry Jam Cake Bars

These Blueberry Jam Cake Bars are quite literally a bar version of cake. They’re soft, moist, and the blueberry jam layer in the middle makes them a delicious dessert option.


  • 2 ¼ cups flour
  • 1 ¼ cups sugar
  • 1 ½ tsp baking powder
  • 1 tsp salt
  • 2 ½ tsp ground cinnamon
  • ¾ cup unsalted butter, melted
  • ¼ cup sour cream, room temp
  • 1 tsp vanilla extract
  • 1 egg
  • ½ cup The Farmer's Wife Blueberry Jam
  • ¾ cup powdered sugar
  • 1-2 tbsp milk
  • ½ tsp vanilla extract


Step 1

Preheat oven to 200°C/180°C fan forced and line a square baking pan with aluminum foil or baking paper.

Step 2

Combine flour, 1 cup of sugar, baking powder, salt, and 1 teaspoon of cinnamon in a large mixer bowl. Set aside.

Step 3

Whisk together melted butter and sour cream in another medium-sized bowl.

Step 4

Add vanilla extract and egg to the butter mixture and whisk until well combined.

Step 5

Add wet ingredients to dry ingredients and beat until well combined.

Step 6

Spread about half of the batter into the bottom of the prepared pan.

Step 7

Spread the blueberry jam into an even layer on top of the batter.

Step 8

Crumble the remaining batter and drop over the blueberry jam, forming an even layer.

Step 9

Combine the remaining 1 1/2 teaspoons of cinnamon and 1/4 cup of sugar in a small bowl, then sprinkle over the top of the batter.

Step 10

Bake bars for 20-25 minutes, then remove from oven to cool completely.

Step 11

If you want to add the glaze, combine the powdered sugar, milk, and vanilla extract in a small bowl and whisk until smooth. Drizzle the glaze over the bars.

Step 12

Cut bars into squares. They can be stored at room temperature or in the fridge. I loved them both ways.
