Butter a 9x9 baking pan and line with parchment (parchment is optional, but helps to remove bars for even slicing.)
Cream butter and sugar with the vanilla paste and salt until fluffy. Scrape down the sides of the bowl a couple of times. I use my stand mixer but you can use electric beaters if you prefer.
Beat in the room temperature egg and scrape down bowl again to get everything evenly combined.
Whisk the flour and baking powder together and slowly add to the bowl with the mixer on low.
Add the chips and nuts (mixer still on low) and mix just until distributed. Do a final stir with a large silicone spoonula just to make sure everything is up from the bottom of the bowl, etc.
Turn the batter into your prepared pan and pat out evenly. It helps to flour your fingers for this job. I take the time to smooth the surface with an offset spatula because this will bake up prettier than a rough surface.
Bake for 30-35 minutes. The bars will just be starting to turn golden around the edges and the center will be slightly puffed. Note: ovens vary greatly, so check them at 30 minutes.
Let the pan cool for about 15 minutes and then, if you've used parchment paper, you can lift the bars out to a cooling rack.
These cookie bars can be sliced while still warm, or you can wait for them to cool. I slice them into 16 squares.
Notes
*I toast my pecan halves on a piece of parchment paper in the microwave (full power) for 2 minutes. Let them cool for a minute, then chop. You can also toast them on a baking sheet in a 350F oven for 10-15 minutes. In either case check them toward the end so they don't burn.
