This low-carb Keto Jelly Slice recipe is creamy in the center with a crunchy base, the three different textures taste amazing in your mouth.
Our Sugar-Free Sweetened Condensed Milk recipe is the key to this delicious dessert, we’ve made our own based on heavy cream to keep the carbs as low as possible.
Important note: The jello that we buy locally sets 500ml/17oz of liquid with a 9g/0.3oz packet – when making this recipe you will need to look for the equivalent setting power. You may need more or less than the recipe below.
This keto jelly slice recipe makes 24 servings. 1 serving is 1 bar and has 2g net carbs.
Leftover Keto Jelly Slice can be stored in the fridge for up to 1 week. It is not suitable for freezing.

How to Make Keto Jelly Slice

- How to make the Low Carb Base
- Preheat oven to 320F/160C.
- Mix the almond flour, sweetener, and melted butter.
- Press into the base of a rectangle baking pan and bake for 10 to 12 minutes, until firm and starting to brown on the edges. We used an 11 x 7in brownie pan.
- Cool the base in the fridge for 15 minutes
- How to make the Creamy Jello Bars Filling
- Dissolve the gelatine in the 1/4 cup of boiling water.
- Mix the Sugar-Free Sweetened Condensed Milk and lemon juice together. Add the gelatin and quickly combine, as the hot gelatin will set fast when added to the cold mixture.
- Pour over the cooled base and set in the fridge for 40 minutes, or until firm.
- How to make the Jello Topping
- Dissolve the jello in 3/4 cup of boiling water.
- Add the cold water and allow the jello to cool to room temperature.
- Gently pour the cooled jello over the set filling. We suggest pouring the jello over a spoon to prevent the layer underneath from dissolving under pressure.
- Set in the fridge for an hour or until completely set before cutting into 24 squares. Enjoy!

Hi you mentioned anything about lining the pan with baking parchment so I put it straight in. Im worried its not gonna come out now ;(
Hi Maria,
I don’t line the pan for this recipe, all you need is a nice thin spatula and the bars will come out easily.
