1. Prepare the oven and pan. Preheat the oven to 350°F. Grease a 13 × 9 × 2-inch baking pan and set aside.
2. Melt the butter and brown sugar. In a medium saucepan over medium heat, combine the brown sugar and butter. Stir until the sugar has dissolved and the mixture is smooth.
3. Add the eggs. Remove the brown sugar mixture from the heat and transfer it to a large mixing bowl. Allow it to cool slightly, then beat in the eggs a little at a time, mixing well after each addition.
4. Combine the dry ingredients. In a separate bowl, whisk together the Authentic Foods Vanilla Powder, Multi-Blend Flour, baking powder, and baking soda.
5. Make the batter. Add the dry ingredients to the brown sugar mixture and stir until fully combined.
6. Fill the pan. Spread the batter evenly into the prepared baking pan. If desired, sprinkle the chocolate chips and chopped pecans or walnuts over the top and gently press them into the batter.
7. Bake. Bake for 20–25 minutes, until a toothpick inserted near the center comes out clean or with a few moist crumbs.
8. Cool and cut. Allow the blondies to cool before cutting into bars.

Baker’s Notes

• For the best butterscotch flavor, use packed brown sugar.
• Chocolate chips, pecans, and walnuts are optional, so you can customize the blondies to your taste.
• Let the blondies cool before cutting for cleaner edges and easier serving.
