To make these bars gluten-free. Swap the all-purpose flour. With a 1:1 gluten-free baking flour blend. This way, you’ll still get that soft, cakey texture. Without any gluten. Be sure to check that your baking powder. And other ingredients. Are certified gluten-free. To avoid any cross-contamination. The maraschino cherries, Grenadine syrup. And other ingredients are naturally gluten-free. So you can still enjoy all the classic flavors. While keeping it safe. For those with gluten sensitivities!
