Low-Carb Version
Looking to reduce carbs? Here’s how to turn these into lower-carb high protein rice crispy treats:
- Swap puffed rice for 2 cups high-protein cereal like Magic Spoon or ProGranola.
- Use ¼ cup sugar-free syrup instead of honey or maple syrup.
- Choose a low-carb whey or plant-based protein powder.
- Keep the nut butter as is. Almond or peanut butter both work beautifully.
This variation still gives you delicious protein krispy treats, just with fewer carbs.
Substitution Tips
- Nut-free? Use sunflower seed butter + rice cereal made without nuts.
- Extra crunch? Add sunflower seeds, cacao nibs, or chopped almonds.
- Want it sweeter? Add a tablespoon of dark chocolate chips or drizzle melted chocolate on top before chilling.
