To make this Easy Lemon Poppy Seed Zucchini Bread gluten-free. You can substitute the all-purpose flour. With a good quality gluten-free flour blend. Look for one that contains xanthan gum. Which mimics the elasticity of gluten. And helps bind the ingredients together. If your blend doesn’t include it. You might want to add about 1/2 teaspoon of xanthan gum per cup of flour. Additionally, ensure that your baking powder and poppy seeds. Are certified gluten-free. As cross-contamination can sometimes be an issue. The texture may be slightly different. But the flavor will remain just as delicious. This adaptation makes the recipe accessible. To those with gluten sensitivities. Allowing everyone to enjoy. The bright, zesty flavors of this delightful bread.
