Butterscotch is like the forgotten flavor.
It’s so rich and delicious, but people always tend to choose chocolate, peanut butter, or lemon desserts over butterscotch.
But can I be honest here?
I think Butterscotch is my favorite of all flavors. Today’s Butterscotch Marshmallow Bars are a hidden gem of a dessert.
It’s what you get when you want a Butterscotch s’more. Something sweet and gooey…that’s not all chocolate.
And when you eat these chilled out of the refrigerator? Whole new level of flavor!
How to make Butterscotch Marshmallow Bars
Preheat oven to 350 degrees F. Line a 13×9 baking dish with parchment paper. Set aside.
In a small glass bowl (or other microwave safe bowl), melt butterscotch morsels with butter in the microwave for 30 seconds. Stir, heat an additional 30 seconds. Stir, if not smooth yet, heat an additional 15 seconds.
In a large mixing bowl, add brown sugar, eggs, and vanilla extract. Mix in melted butterscotch chips, flour, baking powder, and salt.
Fold in marshmallows and chocolate chips. Pour batter into prepared baking dish.
Bake for 18-22 minutes, until lightly browned. Cool completely.
Refrigerate at least one hour. Cut into bars and enjoy!
Can you freeze Butterscotch Bars
Once these bars have cooled completely, you can either freeze them in individual bars or as a whole. Wrap in plastic wrap and foil if freezing whole.
Or slide bars into a freeze Ziploc bag and freeze for up to 3 months.
Thaw in refrigerator overnight. ENJOY.
