Blackberry & Blueberry Cake Bars

These incredibly easy-to-make cake bars get a touch of sparkle and crunch from a sprinkle of turbinado sugar over the top. If you use frozen berries, thaw and pat them dry before topping the batter with them.

Nutrition Profile:


  • 2 teaspoons unsalted butter plus 4 tablespoons, at room temperature, divided

  • ½ cup granulated sugar

  • ¼ cup canola oil

  • 1 large egg

  • 1 teaspoon vanilla extract

  • 1 cup white whole-wheat flour

  • 1 teaspoon baking powder

  • ½ teaspoon salt

  • ½ cup low-fat milk

  • 1 cup fresh blackberries

  • 1 cup fresh blueberries

  • ¼ cup finely chopped almonds

  • 2 tablespoons turbinado sugar


  1. Preheat oven to 350 degrees F. Coat a 9-inch-square baking pan with 2 teaspoons butter.

  2. Beat the remaining 4 tablespoons butter, granulated sugar and oil in a stand mixer fitted with a paddle attachment, or with a hand mixer, until light and fluffy, about 2 minutes. Beat in egg and vanilla until smooth.

  3. Whisk flour, baking powder and salt in a medium bowl. Add the dry ingredients to the wet ingredients and mix until halfway combined. Add milk and mix just until combined. Do not overmix.

  4. Spread the batter in the prepared pan. Sprinkle blackberries and blueberries over the top and lightly press them into the batter. Sprinkle with almonds and turbinado sugar.

  5. Bake until puffed and golden and a toothpick inserted into the center comes out clean, 40 to 45 minutes.

  6. Let cool slightly, then cut into 9 squares.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
