Betty Crocker Devil's Food Cake Mix--Soy Free in Gluten-Free Recipes & Cooking Tips Posted December 23, 2013 · Report to Admin While browsing the grocery aisles the other day I noticed Betty Crocker gluten free products have a new design on the box.....I loved their Devil's Food cake mix when it first came out, but then they switched the flour mixture to a formula that included soy flour, which I am allergic to. Out of curiosity I picked up the box and read the ingredients.......no more soy!! The box does say "may contain soy ingredients" but I've never had an issue with many products that contain the words "may contain xxxxx". I live at 4,000 feet and never had a problem with this product coming out perfect every time. BC is also now selling an all purpose rice flour blend. I'm so tired of cooking everything from scratch because of my food allergies, that I am now leaning toward buying convenience mixes.....at a reasonable price. I also love the King Arthur brand, but BC often has coupons which I always use. Kudos to Betty Crocker. I, too, was thrilled to see it no longer has soy flour. I had a very adverse reaction last summer that lasted for a couple of days. we have been eating a cake I made with lemon icing yesterday. So good!
