Why You’ll Love This Recipe

If you’re like me, there is nothing better than a crisp, refreshing drink on a hot summer day. Sometimes water just doesn’t cut it! Enter keto dirty diet coke, the perfect soda upgrade for your low-carb lifestyle.

This version has everything: fizz, flavor, and that creamy swirl you usually only get at fancy soda shops. Plus, it’s quick to make and even quicker to customize. I use Olipop Vintage Cola for a gut-friendly base with only 3g net carbs, and I love how the coconut and lime flavors play together. It’s a soda that actually tastes like something special.

Ingredients You’ll Need

  • Keto-Friendly Cola: I love Olipop Vintage Cola. It tastes just like Diet Coke to me, but it’s made with prebiotics, plant fiber, and botanicals. Only 3g net carbs!
  • Fresh Lime Juice: Brightens the drink with a crisp citrus kick. I usually squeeze half a lime right in.
  • Creamer: I like Nutpods. Original or French Vanilla are both great. You can also use unsweetened coconut cream if you’d like a richer, thicker version.

Make It Your Own: Swaps + Variations

  • Coconut Options: Use Nutpods, coconut cream, or even a keto-friendly coconut syrup if you have one. Each gives a slightly different texture and sweetness.
  • Soda Swaps: I love Olipop, but Zevia, Diet Coke, or another sugar-free cola works too.
  • Vanilla Vibe: Want a little extra sweetness? Try the French Vanilla Nutpods.
  • Spiked Version: Add 1.5 oz of white rum to turn this into the ultimate low-carb cocktail. It’s perfect for summer Friday nights or backyard BBQs.

Recipe FAQs

Can I use any diet soda?

Yes! Any diet soda like Zevia or classic Diet Coke works. Just be sure to check the label for carbs and sweeteners if you’re keto.

Is coconut syrup keto?

Most traditional coconut syrups aren’t, but you can find sugar-free options online. I usually stick to unsweetened coconut cream or Nutpods.

What’s a good non-dairy creamer for this? 

Nutpods are my go-to. They’re creamy, unsweetened, and dairy-free. Coconut cream is another great choice.

Can I turn this into a cocktail?

Yes! Just add a shot (about 1.5 oz) of rum to make it a dirty Diet Coke cocktail. It’s light, fun, and great for summer parties.

This keto dirty diet coke is the ultimate low-carb treat! Bubbly, creamy, citrusy, and ready in under a minute. It’s one of my favorite ways to stay cool and refreshed without breaking from keto. Let me know if you try it!
