Introduction

Can you tell we are obsessed with orange creamsicle? Our Low Carb Orange Creamsicle Cake was the first proof — this is the one you can drink.

Orange creamsicle is the best summer flavor there is: sweet and refreshing on a hot summer’s day. The good news is you don’t have to wait on an ice cream truck to get it, or even own a blender. Four ingredients go into a shaker bottle, you shake for about five minutes, and the freezer does the rest.

What you get is thick and creamy enough to drink through a straw or eat with a spoon. Just a heads up: no oranges were squeezed in the making of this recipe.

Key Ingredients And Tools

Heavy Cream

Heavy cream is the base, and it is the reason this works without a blender. Shaken hard enough it thickens on its own, and in the freezer its fat is what keeps the result creamy instead of icy. A thinner milk will not do either of those things, which is why the recipe is a cup of cream rather than a cup of something lighter.

Dr. Kellyann Collagen Cooler Orange Cream

The orange comes from a packet: Dr. Kellyann’s Collagen Cooler in Orange Cream.

This collagen cooler is what provides the orange flavor in our keto orange creamsicle smoothie. It’s flavorful, and a packet fits a low-carb day easily. That makes it a practical stand-in for fresh orange, which is harder to fit — a medium one carries around 12g of net carbs. Our guide to oranges on keto breaks down whole fruit, juice, zest, and extracts by serving.

A packet lists 4g of total carbohydrate against 3g of fiber — the label is photographed above.

Lakanto Monk Fruit Sweetener

Two tablespoons of granulated Lakanto go in with everything else. The packet brings some sweetness of its own, so taste before you commit to the full amount — this is the one ingredient here worth adjusting to your own preference, and it dissolves as you shake.

Vanilla Extract

A teaspoon of vanilla is what turns orange into creamsicle. Orange and cream on their own taste like orange and cream; the vanilla is the bit your memory is actually reaching for.

Where you see an em dash: one of the ingredients in this recipe does not publish a figure for that row, so we cannot add one up honestly. We would rather show you nothing there than a zero we cannot stand behind.

About these numbers: We are home cooks, not certified nutritionists. Nutrition is shared as a courtesy. We pick a representative product for each ingredient, and our recipe system works out the totals from the amounts in this recipe, so please treat them as a helpful estimate rather than a guarantee. The brands you buy, any swaps you make, and how generously you portion the recipe will all move these numbers.

Directions

  1. Gather all your ingredients and a blender bottle (or any container with a lid that you can vigorously shake).

    Use a measuring cup and spoon to accurately proportion your ingredients.

  2. Pour all your ingredients into the blender bottle or container of your choice.

    Pour heavy cream, Dr. Kellyann Collagen Cooler Orange Cream, Lakanto Monk Fruit Sweetener, and vanilla extract into your chosen container. Note: adjust the amount of sweetener you add according to your preference. Add more for a sweeter creamsicle smoothie, or add less if you want it to be less sweet.

  3. Shake your chosen container vigorously until the smoothie mixture begins to thicken.

    This should take about five minutes or so depending on how you shake the container.

  5. When the smoothie thickens, place it in the freezer.

    Let it freeze there for at least three hours or until it reaches the consistency that you desire. (Note: before freezing, we added some orange food coloring to our creamsicle smoothie for appearance)

  6. Serve your keto orange creamsicle smoothie in a glass jar and top it off with whipped cream.

    Get a straw and get to drinking your cold and refreshing orange creamsicle smoothie.

    Or if you're like me and want my creamsicle to be more ice cream-like, serve it in a cup or small bowl. Top it off with a dollop of whipped cream, and get yourself a spoon. Enjoy your tasty and fruity orange creamsicle smoothie!

Notes

Preparation

  • Don’t want to freeze your keto orange creamsicle smoothie? You can make it with a blender instead. Pour all your ingredients into a blender. Add a handful of ice cubes if you want your smoothie to be colder and thicker. Blend on high speed until all the ingredients are well combined and the mixture is smooth and creamy. Transfer your smoothie into a glass and serve immediately. Enjoy!

  • Garnish it with a keto-friendly topping. A dollop of whipped heavy cream, a sprinkle of grated orange zest, unsweetened shredded coconut, or a little grated dark chocolate all work as finishing touches, and a slice of orange on the rim of the glass looks the part.

  • If you want a stronger orange, fresh zest is the thing to reach for — it is almost all aroma and very little else. Juice does it too, but the carbs in this drink are low because no fruit is in it, so that is the trade you are making.

Storage

  • This one is made to be eaten out of the freezer, so leftovers are already where they need to be — keep them covered, in a freezer-safe container with a lid rather than the open shaker bottle. The longer it sits the firmer it gets, so give it a few minutes on the counter before you go at it with a straw.

Serving Suggestions

  • This recipe yields approximately two servings.
  • Serve in a glass jar (if you want to drink it) or a small bowl (if you want to eat it like cream).

Frequently Asked Questions

Are oranges keto?

One medium orange has about 12 grams of net carbs, so the whole fruit can be difficult to fit into a strict keto day. This smoothie uses an orange cream collagen mix instead; our guide to oranges on keto compares whole fruit, juice, zest, and extracts.

Can I use a different type of milk instead of heavy cream?

Heavy cream is what the recipe is built around — it is what thickens when you shake it, and it is what makes the frozen result creamy rather than icy. A thinner milk does neither, so swapping it out changes what you get rather than adjusting it.

If you want to try anyway, almond or coconut milk will give you a lighter, icier result, and full-fat coconut milk or coconut cream is the closest thing to the original in body. Treat either as your own experiment rather than this recipe, and tell us how it went in the comments.

Can I make this recipe dairy-free?

Heavy cream is the only dairy in the drink itself, so that is the single thing to replace — the collagen packet, the sweetener and the vanilla are all dairy-free already. Full-fat coconut milk or coconut cream is the usual stand-in, and it is the one with enough fat to behave anything like the cream does. Coconut whips and freezes differently, though, so expect a different texture rather than the same one.

Then there is the whipped cream on top, which the last step and the garnish note both call for and which is easy to miss because it arrives after the drink is already made: leave it off, or swap in whipped coconut cream or another dairy-free topping. See the milk answer above for what else changes.

Can I make this keto orange creamsicle smoothie ahead of time?

It is already a make-ahead recipe. In the shaken version the three hours in the freezer are part of making it, not an optional extra, so shake it in the morning and it is ready that afternoon. Longer than that is fine too — it just keeps getting firmer, so give it a few minutes on the counter before you try to get a straw into it.

The blender version in the recipe notes is the one to use if you want it immediately; that one goes straight into the glass.

Wrap Up

Shake it in the morning and it is waiting for you in the afternoon — through a straw if you catch it early, with a spoon if you leave it longer. Either way is the same four ingredients and the same shaker bottle.

Correction — October 15, 2026: One answer said this smoothie was best drunk immediately, while the recipe needs three hours in the freezer. The freezing is part of making it, and the answer now says so.
