Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Line a loaf pan with parchment paper for easy removal.
In a large bowl, whisk together the dry ingredients: gluten-free flour, baking powder, sugar and salt.
In another bowl, combine the wet ingredients: eggs, maple syrup, oat milk, and fat-free yogurt. Beat well until smooth.
Gradually add the wet ingredients to the dry ingredients, mixing until just combined. Don't overmix!
Gently fold in the chopped pineapple with a spatula.
Pour the batter into your prepared loaf pan.
Bake for 55 minutes, or until a toothpick inserted into the center comes out clean.
Let the bread cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
