🍨 Celebrate National Hot Fudge Sundae Day – The Keto Way!
July 25th is National Hot Fudge Sundae Day — a time-honored celebration of one of America’s most iconic desserts. At Lang’s Chocolates, we’re taking this classic treat to the next level with a keto-friendly twist that doesn’t sacrifice flavor, texture, or indulgence. Using our Keystone Pantry Vanilla Ice Cream Mix, a rich homemade sugar-free hot fudge sauce, and a fluffy keto whipped cream, you’ll enjoy all the nostalgia of a traditional sundae—without the sugar.
But before we dive in, let’s take a moment to explore how this beloved dessert came to be.
đź•° A Sweet Slice of Sundae History
The exact origin of the ice cream sundae is debated, but most food historians trace its roots to the late 1800s. One popular story hails from Evanston, Illinois, where laws prohibited the sale of soda on Sundays. Local soda fountains, looking to satisfy the weekend crowds, replaced soda with syrup over ice cream, giving birth to the “Sunday soda” — eventually becoming known as the “sundae.”
Whether it was born of blue laws or just clever innovation, the sundae has remained a beloved treat for over a century. Now, we’re giving it a keto revival — so you can celebrate history with a low-carb scoop.

2 cups heavy cream
-
1 cup unsweetened almond milk (or water)
📝 Why These Ingredients?
-
Keystone Pantry Ice Cream Mix: Made without sugar and designed for the keto lifestyle, this mix is creamy, scoopable, and churns into soft-serve or firm ice cream depending on your freezer.
-
Heavy Cream: Adds richness and body, ensuring a creamy texture.

🍫 Part 2: Keto Hot Fudge Sauce

1/4 cup unsalted butter
-
1/2 cup Keystone Pantry Allulose
-
1 tbsp unsweetened cocoa powder
-
1/2 tsp vanilla extract
-
Pinch of sea salt
📝 Why These Ingredients?
-
Keystone Pantry Allulose: A natural rare sugar that behaves like traditional sugar when heated, creating a luscious, thick syrup without the crystallization issues other sugar alcohols can cause.
-
Chocolate Chips & Cocoa Powder: Provide deep chocolate flavor with richness and sheen.
-
Heavy Cream & Butter: These fats give the fudge its signature gloss and mouthfeel.
-
Vanilla & Salt: Enhance and balance the sweetness, giving it that classic “fudge shop” flavor.

In a small saucepan over medium heat, melt butter and cream together.
-
Whisk in the allulose until fully dissolved.
-
Add chocolate chips and cocoa powder, stirring until smooth.

Remove from heat and stir in vanilla and sea salt.
