Ingredients

2 cups mixed berries, such as raspberries and blackberries 

1/2 cup sugar 

3 cups whole-wheat flour 

2 teaspoons baking powder 

1 teaspoon kosher salt 

4 large eggs 

3 1/2 cups whole milk 

1/2 cup extra-virgin olive oil 

1/2 teaspoon baking soda 

2 teaspoons pure vanilla extract 

Greek yogurt and pure maple syrup, for serving 

Preparation

Preheat a Belgian-style waffle iron. Toss berries with 1/4 cup sugar, lightly mashing some with the back of a spoon.

In a large bowl, whisk together flour, baking powder, and salt. In another bowl, whisk together eggs, milk, oil, remaining 1/4 cup sugar, baking soda, and vanilla. Whisk wet ingredients into dry mixture just until combined.

Ladle 1 cup batter into waffle iron. Cook until golden and crisp, about 6 minutes. Repeat with remaining batter, whisking between batches for even cooking. Serve warm, with yogurt, macerated berries, and syrup.
