Ingredients:
- 1 box (15.25 oz) Devil's Food Cake Mix
- 1 cup water
- 0.5 cup vegetable oil
- 3 large eggs
- 1 can (14 oz) sweetened condensed milk
- 1 cup salted caramel sauce
- 8 oz whipped topping, thawed
- 1 cup crushed toffee bits
Instructions:
- Heat the oven to 350°F (175°C) and grease your 9x13 inch pan thoroughly. Note: Proper greasing prevents the saturated cake from sticking to the corners later.
- Combine the ingredients. In your mixing bowl, add the cake mix, water, vegetable oil, and eggs.
- Aerate the batter. Beat on medium speed for exactly 2 minutes. Wait until the batter is smooth and slightly lightened in color.
- Bake the base. Pour into the pan and bake for 30–35 minutes until a toothpick comes out with just a few moist crumbs.
- Create the infusion ports. Remove the cake and immediately use the wooden spoon handle to poke holes across the surface at 1 inch intervals. Stop once you have a grid of deep craters.
- Blend the liquids. Whisk the sweetened condensed milk and salted caramel sauce together in a separate bowl.
- Saturate the sponge. Pour the mixture slowly over the warm cake. Ensure the liquid fills every hole before spreading the remainder on top.
- The maturation phase. Allow the cake to reach room temperature on the counter, then refrigerate for 8 to 12 hours.
- Apply the velvet layer. Spread the thawed whipped topping evenly over the cold cake surface.
- Add the final crunch. Garnish with the cup of crushed toffee bits until the top is fully textured and glittering.
