how to store Oat Flour Peanut Butter Protein Muffins

tips to make Oat Flour Peanut Butter Protein Muffins
- Use ripe bananas for natural sweetness and moisture.
- If you want a lower sugar option, reduce the honey or maple syrup.
- Experiment with different add-ins like dried fruits or seeds for extra texture.
- Make sure not to overmix the batter, as this can make the muffins dense.
variation
You can easily switch up the flavor by using almond butter instead of peanut butter, or you could add cocoa powder for a chocolate version. Try using different fruits like blueberries or strawberries instead of bananas or applesauce!
FAQs
Can I make these muffins vegan?
Yes! You can substitute eggs with flax eggs (1 tablespoon flaxseed meal mixed with 2.5 tablespoons water per egg) and use a plant-based milk.
Can I use regular flour instead of oat flour?
Yes, you can use all-purpose flour, but the muffins will not be gluten-free.
How do I know when the muffins are done?
Insert a toothpick into the center of a muffin. If it comes out clean or with a few crumbs, the muffins are ready!
