Instructions
Preheat oven to 350 degrees.
Combine softened butter and peanut butter in large mixing bowl. Blend until smooth.
Next, add the brown and white sugars. Blend until smooth, then stir in the vanilla extract.
Add eggs, one at a time; stir until just combined.
In a medium mixing bowl, mix the flour, baking powder and salt. Then add this mixture to the large bowl. Stir with a spoon until just combined.
Stir in the butterscotch and chocolate chips until just combined.
Spread this mixture into a well-greased square pan; optional to line the pan with parchment paper for easier removal.
Bake for 30-35 minutes (see recipe notes below for tips).
Allow to cool for 10 minutes. Then loosen from the edges of the pan and cut into squares!
Notes
When you’re adding the dry ingredients, stop mixing the second you stop seeing streaks of flour. If you over-mix the batter here, you’ll end up with a tough, bread-like bar instead of that signature fudgy blondie texture we’re after!
Don't overbake these! Because of the peanut butter, they’ll continue to firm up as they cool in the pan. Start checking them at the 30-minute mark—you’re looking for golden edges and a center that is set but still has a tiny bit of "jiggle" when you wiggle the pan. If a toothpick comes out with a few moist crumbs (not raw batter!), they are officially perfect.
These bars stay perfect in an airtight container at room temperature for 3–5 days.
They can also be stored in the freezer for up to 3 months! Just wrap individual squares tightly in plastic wrap and store them in a freezer bag. Thaw on the counter for a few hours when the craving hits.
