Making these Caramel Apple Cupcakes is simple if you follow these step-by-step instructions:

1. Preheat your oven to 350°F (175°C). Line a standard muffin tin with cupcake liners.

2. Mix Dry Ingredients: In a large bowl, combine the flour, granulated sugar, brown sugar, baking powder, baking soda, salt, cinnamon, and nutmeg. Whisk until well combined.

3. Cream Butter: In another bowl, beat the softened butter until creamy. Add the eggs one at a time, mixing well after each addition.

4. Add Vanilla and Buttermilk: Stir in the vanilla extract and buttermilk until fully incorporated.

5. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, mixing until just combined. Be careful not to overmix.

6. Fold in Apples: Gently fold in the diced apples, ensuring they are evenly distributed throughout the batter.

7. Divide Batter: Spoon the batter into the prepared cupcake liners, filling each about two-thirds full.

8. 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.

9. Cool: Remove the cupcakes from the oven and allow them to cool in the tin for 5 minutes. Then, transfer them to a wire rack to cool completely.

10. Frost the Cupcakes: Once the cupcakes are completely cool, frost them with your favorite caramel frosting. Drizzle additional caramel sauce over the top for a finishing touch.
