Ingredients
Method
- Heat oven to 350°F (175°C). Grease a 9x13 pan and dust with cocoa powder. Whisk cake mix, buttermilk, oil, eggs, and vanilla until smooth. Pour into pan and bake 22 to 26 minutes, until a toothpick comes out with a few moist crumbs. Cool 10 minutes.
- Melt chocolate chips and stir into sweetened condensed milk. Poke holes across the warm cake and slowly pour the mixture over the top. Let it absorb for 10 minutes.
- In a saucepan over medium heat, whisk butter, brown sugar, evaporated milk, and egg yolks for 4 to 5 minutes until thickened. Remove from heat and stir in coconut and pecans. Cool 5 minutes.
- Spread the topping over the soaked cake. Refrigerate uncovered for at least 2 hours until set.
- Cut into 12 squares and serve chilled or after 10 minutes at room temperature.
Notes
The chilling time (at least 2 hours) is important for clean slices and a fudgy texture. It is not included in the prep or cook time above, so plan ahead. Leftovers keep well covered in the fridge for up to 5 days.
