Ingredients
- 1 box yellow cake mix, approximately 15.25 ounces
- 1 can sweetened condensed milk, 14 ounces
- 1 bag butterscotch chips, 11 ounces
These three ingredients create a sweet, dense dessert bar with a soft center and a lightly golden top.
How to Make 3-Ingredient Butterscotch Bars
Step 1: Prepare the Pan
Preheat your oven to 350°F. Grease an 8-by-8-inch baking pan or line it with parchment paper, leaving a little overhang to make removing the bars easier.
Step 2: Combine the Ingredients
Place the yellow cake mix in a large mixing bowl. Add the sweetened condensed milk and stir until a thick batter forms.
Fold in the butterscotch chips, distributing them evenly throughout the mixture. The batter will be thick and sticky.
Step 3: Transfer to the Pan
Spread the batter evenly into the prepared baking pan. Use a spatula or the back of a spoon to press it into the corners.
Step 4: Bake
Bake for approximately 25 to 30 minutes, or until the edges are lightly golden and the center is set.
Avoid overbaking, as the bars will continue to firm up as they cool.
Step 5: Cool and Slice
Remove the pan from the oven and let the bars cool completely.
Once cooled, lift them out using the parchment paper and cut into squares or rectangles.
Tips for the Best Butterscotch Bars
Use parchment paper. It makes removing the bars much easier and helps prevent sticking.
Don’t overmix. Stir the ingredients just until combined for a pleasant, tender texture.
Watch the edges. The edges should look set and lightly golden, while the center should no longer appear wet.
Cool completely before cutting. These bars are soft when warm. Cooling helps them hold their shape.
Use fresh butterscotch chips. Fresh chips melt and distribute more consistently throughout the bars.
Easy Variations
The basic recipe contains three ingredients, but you can experiment with optional additions if you don’t mind changing the ingredient count.
- Chocolate butterscotch bars: Add a handful of chocolate chips.
- Nutty butterscotch bars: Fold in chopped pecans or walnuts.
- Salted butterscotch bars: Sprinkle a small pinch of flaky salt over the top before baking.
- Extra-rich bars: Drizzle melted chocolate over the cooled bars.
How to Serve Butterscotch Bars
These bars are delicious on their own with a cup of coffee, tea, or cold milk. For a more indulgent dessert, serve a slightly warmed square with vanilla ice cream.
They are also excellent additions to dessert platters alongside brownies, cookies, and other simple baked treats.
Storage Instructions
Store completely cooled bars in an airtight container at room temperature for up to 3 days, provided your kitchen is cool.
For longer storage, refrigerate them in an airtight container for up to 5 days. Let them sit at room temperature briefly before serving for a softer texture.
Can You Freeze Butterscotch Bars?
Yes. Cut the cooled bars into individual portions and wrap them tightly. Place them in a freezer-safe container and freeze for up to 2 months for best quality.
Thaw at room temperature before serving.
Frequently Asked Questions
Can I use a different cake mix?
Yes. White cake mix can work as a substitute, although the flavor and final texture may vary.
Why are my bars too soft?
They may need a little more baking time, or they may not have cooled completely. Let them cool fully before slicing.
Can I use a larger baking pan?
Yes, but the bars will be thinner and may bake faster. Begin checking for doneness earlier than the suggested time.
Do I need an electric mixer?
No. A sturdy spoon or spatula is enough to mix these ingredients.
Can I make these bars ahead of time?
Absolutely. Bake them a day ahead, cool completely, and store in an airtight container until ready to serve.
