Creating delicious S’mores Muffins is simple with these easy-to-follow steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and line a muffin tin with paper liners.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, granulated sugar, brown sugar, baking powder, and salt until well combined.
3. Combine Wet Ingredients: In a separate bowl, beat the egg and then add the milk, vegetable oil, and vanilla extract. Mix until well combined.
4. Combine Mixtures: Gradually pour the wet ingredients into the dry ingredients, stirring gently until just combined. Avoid overmixing.
5. Fold in Add-Ins: Gently fold in the mini marshmallows, chocolate chips, and crushed graham crackers until evenly distributed throughout the batter.
6. Fill Muffin Cups: Spoon the batter into the lined muffin cups, filling each about two-thirds full. You can add a few extra marshmallows or chocolate chips on top for decoration if desired.
7. Bake: Place the muffin tin in the preheated oven and bake for 20-25 minutes or until a toothpick inserted in the center comes out clean.
8. Cool: Once baked, remove the muffins from the oven and let them cool in the tin for about 10 minutes before transferring to a wire rack to cool completely.

These simple steps will guide you in creating mouthwatering S’mores Muffins that are sure to impress!
