Ingredients
Base Layer
1 box yellow cake mix (15.25 oz)
1/2 cup (1 stick) unsalted butter, melted
2 large eggs, room temperature
Filling & Topping
1 can (14 oz) sweetened condensed milk
1 1/2 cups toffee bits
1/2 cup semisweet chocolate chips (optional)
1/2 cup chopped pecans or almonds (optional)
Instructions
-
Preheat & Prepare Pan
Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper or foil, leaving overhang for easy removal. Lightly grease with nonstick spray or butter. -
Mix the Base
In a large bowl, mix the yellow cake mix with melted butter and eggs. Stir until a thick, cookie-like dough forms. Press about two-thirds of the dough into the prepared pan to form an even base. -
Add Gooey Layer
Pour the sweetened condensed milk evenly over the base. Sprinkle with toffee bits and any optional toppings like chocolate chips or nuts. Drop small spoonfuls of the remaining dough over the top. -
Bake the Bars
Bake for 25–30 minutes or until the edges are golden and the center is just set. Remove from oven and allow to cool completely in the pan for best slicing and texture. -
Cool & Slice
Let bars cool to room temperature, then refrigerate for at least 30 minutes for clean slices. Use a sharp knife and wipe between cuts for neat edges.
Notes
-
Don’t skip the lining: It helps with easy removal and prevents sticking from the sweetened condensed milk.
-
Toffee sinking? Toss toffee bits in a little flour before adding them to the pan.
-
Serve warm for gooey texture or chilled for cleaner cuts.
-
These bars store well at room temp for 3 days, or refrigerate/freeze for longer storage.
-
For a holiday twist, add red/green M&Ms or crushed peppermint on top before baking.
