- Wholesome allulose, granulated: A fantastic low-carb sweetener that caramelizes beautifully, giving you that golden richness without the sugar spike.

- Almond flour: A keto staple that forms the base for the shortbread, offering a tender yet sturdy texture.
- Baking powder: Helps the shortbread rise just enough for a delicate crumb.
- Vanilla extract: Infuses warmth and enhances the sweetness in both the shortbread and caramel layers.
- Heavy cream: Essential for the luscious, creamy caramel layer with its rich fat content.
- Sugar-free chocolate: Forms the decadent top layer — smooth, glossy, and perfectly sweetened without the carbs.
- Butter or coconut oil: Blended into the melted chocolate to ensure shiny and silky finish on top.
How to Make Keto Caramel Slice (Millionaire’s Shortbread) Recipe
Step 1: Prepare the Shortbread Layer
Start by preheating your oven to 325°F and lining your baking pan with parchment paper for easy removal. Mix the almond flour, softened butter, granulated allulose, baking powder, and vanilla extract until the dough forms a crumbly but cohesive mixture. Press this evenly into the pan — this creates the crunchy foundation everyone loves. Bake for 15 minutes or until the edges turn a faint golden color, signaling that perfect light crunch.
Step 2: Make the Creamy Caramel Layer
While the shortbread cools slightly, whisk together the heavy cream and allulose in a medium-large saucepan on high heat. Keep a steady watch and stir often; patience is key here as the mixture slowly thickens and reduces, transforming into a gorgeous golden caramel. This process can take 10 to 20 minutes, so don’t rush it! Just before finishing, stir in the vanilla extract for that extra dimension of flavor. Once ready, pour this dreamy caramel evenly over the baked shortbread and let it cool for about 10-15 minutes so it sets.
Step 3: Add the Silky Chocolate Topping
Melt the sugar-free chocolate in short bursts in the microwave or gently in a double boiler until it’s completely smooth. Stir in butter or coconut oil until the chocolate is glossy and creamy. Immediately pour this indulgent layer onto the cooled caramel and gently shake or tilt your pan to spread it evenly. This shiny top coat will harden as it chills, locking in all those delicious layers. Refrigerate the entire slice for 2 to 3 hours until firm.
How to Serve Keto Caramel Slice (Millionaire’s Shortbread) Recipe
Garnishes
To make your Keto Caramel Slice (Millionaire’s Shortbread) Recipe even more irresistible, sprinkle finely crushed toasted nuts like pecans or almonds on the chocolate layer before chilling. A light dusting of sea salt can also elevate the flavors, bringing out the caramel’s richness in a sophisticated way.
Side Dishes
This slice pairs beautifully with a dollop of whipped cream or a keto-friendly vanilla custard to add creaminess and balance. For a beverage, think rich coffee or herbal tea — they complement the decadent flavors without overwhelming the palate.
Creative Ways to Present
Slice into small squares for bite-sized treats at parties, serve alongside fresh berries for a touch of natural sweetness, or layer slices in a pretty jar with parchment separators for a fun keto dessert gift. Whatever way you choose, this slice always looks as impressive as it tastes.
Make Ahead and Storage
Storing Leftovers
Store any leftover slices in an airtight container in the refrigerator. The layers stay fresh and firm for up to two weeks, making it a great make-ahead treat for busy days or unexpected guests.
Freezing
This slice also freezes wonderfully. Place parchment paper between layers of the slice in an airtight container, then freeze for up to one month. When ready to enjoy, simply thaw overnight in the fridge — no loss of that silky caramel or crunchy base.
Reheating
There’s no need to reheat these slices — they’re best enjoyed cold or slightly chilled to preserve the texture of the shortbread and keep the caramel firm. If you prefer a softer caramel feel, leave them at room temperature for 10-15 minutes before digging in.
FAQs
Can I use a different sweetener instead of allulose?
Absolutely! While allulose works best for caramelization and texture, you can substitute with erythritol or monk fruit sweetener. Just note that caramel may turn out less rich or take longer to thicken.
Is this recipe suitable for beginners?
Yes! The steps are straightforward, and the ingredients are simple. Even if you’re new to baking keto desserts, this recipe guides you through delicious layers that come together beautifully.
How thick should the caramel layer be?
About half an inch thickness is ideal. This allows you to taste the buttery richness and creaminess in every bite without overwhelming the crunchy shortbread base.
Can I make this recipe dairy-free?
You can try substituting heavy cream with full-fat coconut milk and use coconut oil instead of butter. However, the texture and flavor may change slightly since dairy fats contribute to the creaminess and caramelization.
What chocolate is best for the topping?
A high-quality sugar-free dark chocolate with at least 70% cocoa content works best. It melts smoothly and provides that perfect balance of bitterness and sweetness to top off the slice.
Final Thoughts
If you’re on the hunt for a keto dessert that tastes indulgent yet fits effortlessly into your low-carb lifestyle, this Keto Caramel Slice (Millionaire’s Shortbread) Recipe is your new best friend. It’s a divine combination of textures and flavors that feels like a special treat but is surprisingly easy to make.

Keto Caramel Slice (Millionaire’s Shortbread) Recipe
This Keto Caramel Slice, also known as Millionaire’s Shortbread, features a crunchy almond flour shortbread base, a rich and creamy homemade caramel layer made with allulose and heavy cream, and a smooth sugar-free chocolate topping. Perfect for a low-carb dessert, this decadent treat is easy to make with simple ingredients and yields 16 satisfying servings.
- Total Time: 2 hours 35 minutes
- Yield: 16 servings
Ingredients
Shortbread
- 2 tablespoons Wholesome allulose, granulated
- 1/4 cup butter, softened
- 1 cup almond flour
- 1/2 teaspoon baking powder
- 1 teaspoon vanilla extract
Caramel
- 1 cup Wholesome allulose, granulated
- 3 cups heavy cream
- 1 teaspoon vanilla extract (optional)
Chocolate
- 6 ounces sugar-free chocolate
- 2 tablespoons butter or coconut oil
Instructions
- Prepare Shortbread Layer: Preheat your oven to 325°F (163°C). Line an 8×8 or 9×9 inch baking pan with parchment paper and set aside. In a medium bowl, combine all shortbread ingredients: granulated allulose, softened butter, almond flour, baking powder, and vanilla extract. Mix well until evenly combined. Press the shortbread mixture firmly and evenly into the lined pan. Bake for 15 minutes or until the top starts to turn a light golden color. Remove from oven and let cool slightly.
- Make Caramel Layer: While the shortbread bakes, combine the heavy cream and 1 cup allulose in a medium-large saucepan. Heat over high heat, whisking continuously and watching closely to prevent boiling over. Continue whisking until the mixture thickens, turns a golden brown color, and reduces by half—this will take approximately 10 to 20 minutes depending on your stove and pot size. In the last minute of cooking, whisk in vanilla extract if using. Remove from heat and allow the caramel to cool for 10-15 minutes, then pour it evenly over the baked shortbread layer.
- Create Chocolate Layer: Place sugar-free chocolate in a microwave-safe bowl and melt it in 30-second increments, stirring after each, until softened and smooth. Add the butter or coconut oil and whisk together until creamy and fully combined. Pour the chocolate evenly over the caramel layer. Gently shake or tilt the pan side to side to help the chocolate spread evenly.
- Chill and Serve: Refrigerate the layered slice for 2 to 3 hours or until the chocolate is firm and set. Once chilled, slice into 16 pieces. Store any leftovers in an airtight container in the refrigerator for up to 2 weeks to maintain freshness.
Notes
- The caramel mixture requires close attention to avoid boiling over—whisk constantly and monitor the heat.
- Use parchment lining to easily lift the slice out of the pan for cutting.
- You can substitute coconut oil for butter in the chocolate layer if preferred.
- Ensure the caramel is cooled slightly before pouring chocolate on top to prevent mixing layers.
- Store the caramel slice refrigerated to keep the layers firm and prevent melting.
