Beat the softened butter with the brown and granulated sugars until the mixture is pale and fluffy. This top-notch technique builds the internal structure of the cookie, ensuring they rise perfectly in the oven rather than spreading into flat puddles.
Stir in the dry instant vanilla pudding mix. This is the professional-grade secret for a high-protein vegetarian snack that stays soft for days. The pudding mix binds the moisture, preventing the cookies from ever turning into hard rocks.
Incorporate the eggs one at a time, followed by the vanilla extract. Using room-temperature eggs is a smart move to keep the butter from clumping, resulting in a smooth, professional emulsion that ensures a consistent, tender crumb.
Gently mix in the flour, baking soda, and salt on low speed. Stop as soon as the flour is no longer visible. Avoiding over-mixing at this stage is vital to maintaining the “melt-in-your-mouth” quality that makes these pudding cookies so unique.
Fold in the semi-sweet chocolate chips and chopped walnuts by hand. The walnuts are a brilliant way to add a high-protein vegetarian boost and a savory crunch that balances the sweet vanilla and chocolate notes.
Scoop the dough into 1.5-inch balls and bake at 350°F for 10 to 12 minutes. Pull them out when the edges are just barely golden but the tops still look soft. They will finish cooking on the hot tray, giving you a top-notch, bakery-style finish.
