What ingredients are in a peanut butter cup?

1. Chocolate: This is the outer shell of the candy and can be made from different types of chocolate, such as milk chocolate, dark chocolate, or white chocolate.

2. Peanut Butter: This forms the creamy center of the candy and is made from roasted and ground peanuts. The peanut butter can vary in consistency and flavor, and may contain additional ingredients such as sugar, salt, or oil.

3. Sugar: Sugar is added to both the chocolate coating and the peanut butter filling to provide sweetness.

4. Milk Solids: Milk solids, in the form of milk powder, butter, or condensed milk, are often added to the chocolate and peanut butter mixture to enhance flavor, texture, and creaminess.

5. Butterfat: Butterfat, usually from cocoa butter or vegetable fats, is added to the chocolate coating to provide smoothness, texture, and melt-in-your-mouth quality.

6. Salt: Salt is added in small amounts to the chocolate and/or peanut butter to balance the sweetness and bring out the flavors.

7. Vanilla Extract: Vanilla extract is commonly added to the chocolate and/or peanut butter filling for flavor enhancement and to complement other ingredients.

8. Emulsifiers: Emulsifiers, such as lecithin, are sometimes added to the chocolate coating to improve its texture, prevent separation, and ensure a smooth finish.

These ingredients can be combined in different proportions and additional variations may exist, leading to different flavor profiles and textures in different brands and types of peanut butter cups.
