Ingredients

Method

Coat 2 standard 6-cup muffin pans with nonstick spray. Whisk baking powder, salt, and 1 1/2 cups flour in a medium bowl. Whisk egg, brown sugar, butter, milk, and ginger in a large bowl; mix in dry ingredients. Toss raspberries with remaining 1 tablespoon flour in a small bowl; gently fold into batter.

Divide batter among muffin cups and bake until a tester inserted into center comes out clean, 25–30 minutes. Let cool 5 minutes in pan before serving.

DO AHEAD: Muffins can be made 1 day ahead. Store airtight at room temperature.
