To make this delicious cake gluten-free, just swap the all-purpose flour for a high-quality gluten-free baking blend (look for one that includes xanthan gum for the best texture). Gluten-free flour blends work well with the butter and lemon flavors, keeping that moist, tender crumb we love. Just double-check that all other ingredients, especially the baking powder, are gluten-free, and you’re good to go. This way, you can still enjoy every rich, lemony bite without any gluten worries!
