You can use a mix of nuts such as almonds, walnuts, hazelnuts, or pecans to replace up to 1 cup of the seeds. Since this is a “seed bread” I kept the recipe nut-free but I’ve made it with walnuts and that’s delicious too! Just make sure any nuts are are finely chopped before adding to the mixture.
The stevia is optional but I find a hint of sweetness really improves the final taste. Alternatives include monk fruit sweetener to keep it sugar-free, otherwise, use 1 tbsp maple syrup or coconut sugar. I used stevia to keep it sugar-free for those that need it. Maple syrup is my preferred sweetener here.
