There's something magical about a root beer float, isn't there? It takes you back to simpler times—maybe to a summer afternoon at the local soda fountain or a family gathering with cousins you haven't seen in years. I remember my grandma making them for us, using her 'secret' ingredient, a dash of cinnamon. It was the best.

Now, I know store-bought root beer is convenient, but trust me, once you taste homemade, you'll never go back. Don't worry, it's surprisingly easy, and the flavor is just so much richer and more complex. Let's get started!

This isn't just a recipe; it's an experience. The fun of mixing the ingredients, the anticipation as the root beer chills, and finally, the pure joy of watching that ice cream melt into the frothy goodness... it's all part of the charm. And seriously, who can resist that first sip? I know I cant!

Oh, and before I forget, a little tip: Don't be afraid to experiment with different types of vanilla ice cream. A good quality French vanilla will add an extra layer of richness, while a simple vanilla bean ice cream will let the root beer flavor really shine. It’s also super important to make sure your root beer is ice cold, so it doesn't melt the ice cream too quickly. Trust me on this one; a warm float is a sad float.

🍽 Ingredients

📖 Instructions

  1. **Brew the Root Beer Concentrate:** In a large saucepan, combine 4 cups of water, 1 cup of granulated sugar, 1/2 cup of brown sugar, 2 tablespoons of root beer extract, 1 teaspoon of vanilla extract, 1/2 teaspoon of sassafras bark (optional, but adds authentic flavor!), and a pinch of cinnamon (grandma's secret!).
  2. **Simmer the Concentrate:** Bring the mixture to a simmer over medium heat, stirring until the sugars are completely dissolved. Reduce the heat to low and let it simmer for about 10 minutes, allowing the flavors to meld together. The aroma should fill your kitchen with a delightful, nostalgic scent.
  3. **Cool the Concentrate:** Remove the saucepan from the heat and let the root beer concentrate cool completely. This will take about an hour at room temperature or you can speed it up by placing the saucepan in an ice bath. Make sure it's really cool before moving on!
  4. **Prepare the Soda Water:** While the concentrate cools, make sure your soda water (or club soda) is ice-cold. The colder, the better!
  5. **Mix the Root Beer:** Once the concentrate is completely cooled, mix it with the ice-cold soda water. Start with a ratio of 1 part concentrate to 3 parts soda water. Taste and adjust the ratio to your liking – some people prefer a stronger root beer flavor. I tend to lean more towards the concentrate side!
  6. **Chill the Root Beer:** Pour the mixed root beer into a pitcher or bottles and chill in the refrigerator for at least 30 minutes. This step is crucial for maximum fizz and flavor. Patience is key, I know!
  7. **Prepare Your Glasses:** Grab your favorite glasses (tall ones work best!) and place them in the freezer for a few minutes to get them nice and frosty. This helps keep your float colder for longer.
  8. **Scoop the Ice Cream:** Scoop 2-3 generous scoops of vanilla ice cream into each chilled glass. Don't be shy with the ice cream – it's the star of the show!
  9. **Pour the Root Beer:** Slowly pour the chilled homemade root beer over the ice cream, filling the glass to the top. Watch as the root beer fizzes and foams around the ice cream.
  10. **Garnish and Serve Immediately:** Add a fun straw and maybe even a cherry on top for a classic touch. Serve immediately and enjoy the nostalgic goodness! Don't wait too long; the best floats are enjoyed right away.

📝 Notes

  • Adjust the sweetness by adding more or less sugar.
  • For a richer flavor, use a good quality vanilla extract or bean.
  • Experiment with different ice cream flavors like chocolate or caramel.
  • Garnish with whipped cream and a cherry for an extra treat!
