If you are very visual, like me, sometimes it's nice to have step by step images of the process.

Make the cake as directed on the package, but stir the chocolate chips into the batter just before baking.

1. Bake cake according to instructions but add ½ cup bittersweet chocolate chips to the batter. Poke holes in warm cake.
2. Add the sweetened condensed milk over the entire cake and let it soak into the holes for a minute or two.
3. Warm the hot fudge sauce and add it. Let it soak into the cake for a minute or two.
4. Cover with the caramel sauce. Cover with plastic wrap and refrigerate overnight.

1. Cover the top of the cake with chopped Butterfingers.
2. Top with the whipped cream mixture.
3. Cover with more crushed Butterfingers.
4. Serve and enjoy!

💭 Tips for success

Expert Tip: Don't chop the Butterfingers bars too small. I like them chopped in larger pieces but you can chop them smaller if you like.

• Most Holy Cow Cake recipes call for whipped topping but I like real whipped cream on top. I stabilize it with just a touch of instant pudding mix so that it stays fluffy and yummy for days as long as it's in the fridge - which isn't very long at our house.
• There's no turning the cake  out, stacking, or anything like that. Bake it, frost it, and serve it in the same pan.
• If you have leftover cake, which is unlikely, be sure to keep it tightly covered in the refrigerator.
• I've made this with homemade chocolate cake and with a boxed mix and there really isn't much difference. This is one of those cakes that you can make when you need something super easy.
• It is much better if you can keep it until the next day- but you absolutely must let it chill for at least 6 to 8 hours.

📖 Variations

• Use Cool Whip instead of the whipped cream
• Substitute Heath Bars for the Butterfingers
• This is great with a butter cake mix
• Yellow cake mix works as well
• Use butterscotch sauce instead of caramel

📞 The last word

This easy Holy Cow cake (or Butterfinger cake recipe - whatever you'd like to call it!) definitely deserves a spot on your "A" list!

It's one of our family favorites - and often requested for birthdays.

I love this recipe for potlucks and family get-togethers because people just go nuts over it. The chocolate cake soaks up all of that sweet, syrupy goodness and it stays  moist forever and a day because of it, too.

Make ahead easy!

The Butterfinger candy bars add crunch and flavor - if you are a fan of them then this is the cake for you. Don't be afraid of adding more chopped up Butterfingers, either... I have been known to double them.
