Hot Fudge Sundae Cake


Ten years ago, a blogger named Jennifer Novic shared a fun recipe for hot fudge sundae cake with us. Her blog is no longer active, but I knew her delicious creation must live on. So I tested and tweaked to create a full dairy-free dessert that is a delicious option for parties or afternoon treats.

How Does Hot Fudge Sundae Cake Work?

This hot fudge sundae cake takes just 15 minutes of preparation, from pulling out the ingredients to popping it in the oven. The method of pouring hot chocolaty liquid over top causes the layers to separate. A chocolate cake floats to the top, and a generous layer of fudgy goodness nestles at the bottom, as you can see in the picture above.

To note, the “fudge sauce” layer is a little thicker than a sauce. It’s got an almost pudding-like texture, but works with the cake and dairy-free ice cream topping for an amazing hot fudge sundae cake experience. For the drizzle of hot fudge on top, I whisk any residual fudgy stuff from the pan with a little water and/or coconut oil. The water just thins it, but the coconut oil initially thins (it melts in) and then thickens it again as it hits the cold ice cream. I like the clingy, thickening effect that a little coconut oil provides.

For the Love of Dairy-Free Ice Cream

Raise a Pint Event! Dairy-Free Ice Cream Recipes, Giveaways and MoreYes, the dairy-free ice cream on top of this hot fudge sundae cake is a MUST. Trust me, it completes the flavor experience, and it adds a complimentary creamy layer.

Speaking of dairy-free ice cream, I actually whipped up this hot fudge sundae cake in honor of the Share a Moment, #RaiseAPint Event and corresponding blogger recipe contest.

Their AMAZING Cashew Milk Frozen Dessert was the inspiration for digging up and rehashing this recipe. Nonetheless, it works great with the Coconut Milk Frozen Dessert, too!

Special Diet Notes: Hot Fudge Sundae Cake

By ingredients, this recipe is dairy-free / non-dairy, egg-free, optionally nut-free, optionally peanut-free, soy-free, vegan, plant-based, and vegetarian.

To keep this hot fudge sundae cake nut-free, omit the nutty topping and use a dairy-free ice cream without nuts, like coconut milk or soy milk ice cream.

For a gluten-free hot fudge sundae cake, swap your favorite gluten-free flour blend for the all-purpose flour. This tends to be a fragile cake that you eat sundae-style, so it’s okay if it is a touch crumbly.

Hot Fudge Sundae Cake
Prep time
Cook time
Total time
Serves: 9 servings
  • 1 cup all-purpose flour (see post above for gluten-free)
  • ⅔ cup sugar
  • 2 tablespoons + ¼ cup cocoa powder, divided
  • 2 teaspoons baking powder
  • ½ teaspoon espresso powder (optional)
  • ½ teaspoon + ⅛ teaspoon salt, divided
  • ½ cup unsweetened dairy-free milk beverage (I use So Delicious Coconut Milk Beverage)
  • 2 tablespoons rice bran, grapeseed or avocado oil (or you favorite baking oil)
  • 1 teaspoon vanilla extract
  • ¾ cup packed brown sugar
  • 1½ cups hot water
  • 1 to 2 pints dairy-free ice cream (I use So Delicious Vanilla or Creamy Cashew Frozen Dessert)
  • Chopped nuts, for topping (optional)
  1. Preheat your oven to 350ºF.
  2. Add the flour, sugar, 2 tablespoons cocoa powder, baking powder, espresso (if using), and ½ teaspoon salt to a mixing bowl. Stir or whisk until combined and any clumps of cocoa are broken up.
  3. Make a well in the flour mixture and add the milk beverage, oil and vanilla. Stir to combine. The batter will be a bit thick.
  4. Scrape all of the batter into a 9x9-inch ungreased baking pan, and spread to even out.
  5. Add the brown sugar, ¼ cup cocoa powder and ⅛ teaspoon salt to your mixing bowl. Add the hot water and whisk to combine. Slowly pour the chocolate liquid all over the batter in your pan.
  6. Bake for 40 minutes, or until a toothpick inserted into just the top cake layer comes out clean. Let cool 10 minutes.
  7. Serve the cake topped with 1 to 2 scoops of the dairy-free ice cream. You can optionally top with nuts and whisk water or coconut oil into any remaining sauce in the pan (it is thick, with a pudding like texture) to drizzle it over the top, too.
Slow Cooker Option: This was shared by Jennifer Novic with us previously. Follow the preparation instructions, but add the cake and sauce ingredient layers to a slow cooker. Cover and cook on HIGH for 2 to 2½ hours or until a toothpick inserted in the cake center comes out clean. Turn the crockpot off and let the cake stand uncovered for 30 to 40 minutes before serving.

  1. I love this! I used to make a similar “pudding cake” before I started eating a plant based diet and I’ve been meaning to veganize it ever since. In the meantime, I’ll just enjoy this delicious treat!
