These homemade sunflower butter and jelly uncrustables are completely nut-free, budget-friendly, and perfect for school lunchboxes. With a simple trick to prevent leaks, they freeze beautifully and taste just like the store-bought version—only better.
Flattening the bread is crucial for a good seal. Use room temperature sunflower butter to prevent tearing. Don’t overfill—stick to the measurements. For a crispy version, air fry a frozen uncrustable at 350°F for 5-6 minutes.
