Pre-heat oven to 350F/180C. Lightly grease and flour, spray or line with parchment paper an 8 inch square pan.
In a medium bowl whisk together the flour, baking powder, salt, cinnamon and chopped nuts.
In a large bowl or stand mixer beat the butter and sugar until creamy, approximately 3 -5 minutes, add the egg and vanilla and beat well. Add the dry ingredients mix just to combine. Spread evenly in the prepared pan, and bake 20-25 minutes, test with a toothpick for doneness. Let cool 10-15 minutes in the pan then move to a wire rack to cool completely before cutting into squares. Top with a dollop of maple whipped cream if desired. Enjoy!
MAPLE WHIPPED CREAM
Whip the cream until soft peaks form then slowly add the maple syrup, whip until stiff.
Notes
How to store the brown sugar bars
Store these brown sugar brownie bars covered in an airtight container for up to 4 days at room temperature. If you like bar cookies chilled, you can store them in the refrigerator for a few days longer.
Can I freeze this brown sugar bar recipe?
Yes! I love to freeze cookies and bars to enjoy for a snack or dessert recipe later. To freeze, cool completely then wrap bars in plastic wrap and place in a freezer safe container. They can stay frozen for up to 3 months. Thaw and enjoy!
