Finely chop the pecans with a sharp knife or pulse them briefly in a food processor. Avoid grinding them into a paste because the natural oils can make the mixture greasy.

If you are crushing whole vanilla wafers, process them into fine crumbs. Measure one cup of crumbs after crushing to ensure the mixture has the correct consistency.

Place the chopped pecans and vanilla wafer crumbs in a large mixing bowl. Add the optional ground cinnamon and stir until everything is evenly distributed.

Step 2: Mix the Condensed Milk, Butter, and Vanilla

In a separate bowl, combine the sweetened condensed milk, softened butter, and vanilla extract. Stir until the mixture looks smooth and creamy.

Add the wet ingredients to the pecan and crumb mixture. Using a silicone spatula or sturdy spoon, mix thoroughly until the crumbs and nuts are evenly coated.

The mixture should feel moist and slightly sticky but firm enough to shape. If it appears excessively wet, add a little more vanilla wafer crumb, one tablespoon at a time.

Step 3: Shape the Pecan Balls

Scoop approximately one tablespoon of mixture at a time. Roll each portion gently between your palms to form a small ball.

If the mixture sticks to your hands, lightly dampen your palms or refrigerate the mixture for 10–15 minutes before continuing.

Place the shaped balls on a parchment-lined baking sheet or tray. Try to keep them approximately the same size so they chill evenly and look attractive when served.

Step 4: Chill Until Firm

Transfer the tray to the refrigerator and chill the pecan balls for approximately 30–45 minutes.

This step helps the butter firm up and allows the vanilla wafer crumbs to absorb moisture from the condensed milk. As a result, the balls become easier to handle and less likely to fall apart during coating.

If the mixture still feels soft, leave the balls in the refrigerator a little longer before moving to the next step.

Step 5: Coat and Decorate

For the simplest finish, place the powdered sugar in a shallow bowl and roll each chilled pecan ball until lightly coated.

For a richer candy-style treat, melt the chocolate wafers according to the package directions. Dip each chilled ball into the melted chocolate, allowing any excess to drip back into the bowl.

Place the coated balls on parchment paper and sprinkle with finely chopped pecans before the chocolate sets. Refrigerate until the coating is firm.

Arrange the finished pecan balls on a serving plate or in mini paper candy liners. Serve chilled or allow them to stand briefly at room temperature before enjoying.
