To make Chrissy Teigen’s Banana Bundt Bread gluten free, replace the all-purpose flour with a high-quality 1:1 gluten-free baking flour blend that includes xanthan gum. Be sure to confirm that the vanilla pudding mix, shredded coconut, chocolate, and baking soda are certified gluten free, as packaged products can sometimes contain hidden gluten or cross-contact risks. Also use gluten-free flour when dusting the bundt pan. The rest of the recipe can remain the same, though the final texture may be slightly different depending on the flour blend used.
