Step 1

Preheat the oven to 350°F. Lightly spray a 13 x 9 x 2-inch baking pan with cooking spray.

Step 2

In a medium bowl, gently stir together the berries, 1/4 cup sugar substitute, the water, lime juice, and ginger. Let the berry mixture stand for at least 15 minutes so the juices can accumulate.

Step 3

In a small bowl, stir together the flour, baking powder, salt, and the remaining 1/2 cup sugar substitute.

Step 4

In a large bowl, whisk together the milk, oil, yogurt, and vanilla.

Step 5

Add the flour mixture to the milk mixture, stirring just until no flour is visible. Don’t overmix.

Step 6

Pour the batter into the baking pan. Using a spatula, spread the batter in the pan. (The batter doesn’t have to touch the edge of the pan; it will spread while baking.) Top with the berry mixture.

Step 7

Bake for 50 minutes, or until a wooden toothpick inserted in the center comes out clean.
