To make this Classic Grape-Nuts Bread gluten-free, swap out the all-purpose flour for a 1:1 gluten-free flour blend that’s meant for baking. Make sure the Grape-Nuts cereal you’re using is labeled gluten-free, as some versions contain gluten. If you can’t find a gluten-free Grape-Nuts, try using a similar nutty, crunchy cereal that’s certified gluten-free. With these small adjustments, you’ll have the same warm, cozy loaf everyone can enjoy, gluten-free and full of flavor!
