Preheat the oven to 350°F (180°C) and line a muffin tin with paper liners.
In a large bowl, mix sugar, brown sugar, eggs, Greek yogurt, and peanut
butter until well combined.
Add the oil, mashed bananas, and vanilla extract. Stir until smooth.
Add the flour, baking powder, baking soda, chocolate chips, and chopped
chocolate. Gently mix with a spatula until fully combined.
Fill the muffin cups all the way to the top to create a high muffin top that
slightly overflows when baked.
Bake for 22 minutes, or until a toothpick inserted in the center comes out
clean.
Let the muffins cool for a few minutes before removing them from the tin.
Notes
Oil Substitutes: You can replace coconut oil with vegetable oil, canola oil, or melted butter for a richer flavor. Sweetener Options: Swap white sugar with honey, maple syrup, or coconut sugar for a natural alternative. Reduce slightly if using liquid sweeteners. Flour Alternatives: Use whole wheat flour for added fiber, or a 1:1 gluten- flour blend to make them gluten-free. Dairy-Free Version: Replace Greek yogurt with coconut yogurt or unsweetened applesauce for a dairy-free option. Nut-Free Option: If avoiding peanuts, use almond butter, cashew butter, or sunflower seed butter instead of peanut butter. Extra Crunch: Add chopped nuts like walnuts, pecans, or almonds for added texture. Storage: Keep muffins in an airtight container at room temperature for 4 days or in the fridge for up to 5 days. You can also freeze them for up to 3 months.
