To make this Cranberry Olive Oil Cake Recipe gluten free, replace the all-purpose flour with a certified gluten-free 1:1 baking flour blend. Verify that the almond flour, baking powder, baking soda, cinnamon, Greek yogurt, vanilla extract, sliced almonds, powdered sugar, and cranberries are labeled gluten free or free from gluten-containing additives. Use clean mixing bowls, utensils, measuring cups, and a clean springform pan to prevent cross-contact with gluten-containing ingredients.
