How to Make Blue Treats Without Food Dyes

To make the pretty blue jello layer I used butterfly pea tea flowers which I bough online (here's where to get them on Amazon US and Amazon UK).

You'll only need a few small flowers for a vibrant blue effect (10 to 20 depending on the desired effect). The longer you steep the flowers in water, the more vibrant the layer will become.

Butterfly pea tea tastes neutral so you can add any sugar-free extracts to add the flavor you like. Strawberry, blueberry or raspberry extract will work best in these low-carb jello jars.

If you don't have and can't get butterfly pea tea flowers, simply use a few drops of natural blue coloring or add 1 to 2 teaspoons of blue spirulina powder like I did in these Keto Rainbow Cheesecakes.

Recipe Tips

  • Can't have dairy? Swap coconut cream for the heavy whipping cream.
  • Want to make it sweetener-free? Thanks to the sweetness from fresh berries and cream, this recipe will work without sweeteners.
  • Instead of 4 gelatin sheets you can use 1 tablespoon gelatin powder or 1 tablespoon agar powder if you want to make it vegetarian (or vegan if you also replace the cream with coconut cream). This will be enough to soft-set 4 cups (480 ml) of liquid.
  • Want to change the jello color? Skip the berry extract and instead add juice from one lemon. When combined with acidic ingredients, blue butterfly pea tea turns into pretty purple!

Ingredients (makes 4 servings)

Blue jello layer:
Red & white layer:


  1. To prepare the blue jello layer, place 10 to 20 butterfly pea tea flowers into a jar filled with 2 cups of cold water (I used 20 flowers for a deep blue jello). Keto Red, White & Blue Jello Jars
  2. Let it steep at room temperature for at least 30 minutes or in the fridge for up to 8 hours. Keto Red, White & Blue Jello Jars
  3. Pour a few tablespoons of water over the gelatin sheets and leave to soften for a few minutes. (Note: check the recipe tips for vegetarian options and dairy-free options.)
  4. Strain the liquid through a sieve into a saucepan and discard the flowers. Heat up over a medium-high heat. Once hot, take off the heat. Add the granulated sweetener (Erythritol, Swerve or Allulose) and sugar-free extract (blueberry, strawberry or raspberry will work best). Keto Red, White & Blue Jello Jars
  5. Add the softened gelatin sheets and stir until dissolved. Let it cool down to room temperature. (You can speed it up by placing the saucepan into a bowl filled with ice water.)
  6. Divide between 4 glass jars and refrigerate until set. This will take 1 to 2 hours.
  7. When set, prepare the cream layer. Using an electric mixer, whip the cream until slightly thickened. Add powdered sweetener and vanilla extract and whip until stiff peaks form. Keto Red, White & Blue Jello Jars
  8. Slice the strawberries. To assemble, spoon half of the whipped cream on top of the jello layer or use a piping bag (it will be less messy if you do).
  9. Top with the sliced strawberries, and then top with the remaining cream. Keto Red, White & Blue Jello Jars
  10. Serve immediately or store in the fridge for up to 4 days, ideally covered to prevent the cream from drying out. Keto Red, White & Blue Jello Jars

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

I have just post a question about blue butterlfy beans for natual dying after reading the recipe of your wonderful Smurf icecream, then I've found this other recipe that teaches detailes about this ingredients, so let's buy it and start making both these blue summer-refreshing treats 😊 ! You're a godsend inspiring with enthusiasm and precision: thank you!

I am totally in love with butterfly pea tea. It doesn't taste of anything so it's perfect for getting that natural blue (or purple if you add lemon) effect and will work with any flavour. Now I can't stop thinking about all those summer treats! 😊

Thank you, Martina! I'll have to try it and experiment all the ideas that blow in my mind to color this summer 😊 I'm already doing researches of pure powders rather than flowers to infuse, but with an eye on the label as always since I've noticed that many brands add maltodextrin to powder... they won't have me ;- ) !

Good point! I've seen butterfly pea powder too but haven't noticed if they put maltodextrin. I think most will put some kind of anti-clumping ingredient.
