Bourbon Vanilla Bean Milkshake

Vanilla bean milkshakes get an adult upgrade with a splash of smooth bourbon and a crunchy graham cracker rim. Trust me, it's the perfect treat for a warm evening.

Serving: 2 | Prep Time: 10 minutes | Cooking Time: 0 minutes

Ingredients

• 2 cups vanilla ice cream
• 2 oz bourbon
• 1 vanilla bean
• 1/2 cup heavy cream
• 1 tbsp powdered sugar
• 1/4 cup crushed graham crackers

Instructions

1. Split the vanilla bean lengthwise and scrape the seeds. Set aside. (Tip: Use a sharp knife to split the bean easily.)
2. In a small bowl, combine heavy cream and powdered sugar. Whip with a hand mixer until stiff peaks form. (Tip: Chill the bowl and beaters for better volume.)
3. Place crushed graham crackers on a shallow plate. Dip the rim of each glass into the whipped cream, then into the graham crumbs to coat. Set aside.
4. In a blender, combine vanilla ice cream, bourbon, and vanilla bean seeds. Blend until smooth and thick. (Tip: For a thinner shake, add a splash of milk; for thicker, use less ice cream.)
5. Pour the milkshake into the prepared glasses. (Tip: Pour slowly to keep the graham rim intact.)
6. Top with remaining whipped cream and a sprinkle of graham crumbs if desired. Serve immediately.

Don't skip the graham cracker rim—it adds a nostalgic s'mores vibe that pairs beautifully with the bourbon and vanilla. This shake is creamy, boozy, and surprisingly easy to whip up any night of the week.

Salted Caramel Rum Milkshake

Salted caramel and rum? Yes, please. This milkshake is your new favorite adult treat—creamy, boozy, and topped with all the good stuff. It comes together in minutes but feels like a fancy dessert.

Serving: 2 | Prep Time: 10 minutes | Cooking Time: 0 minutes

Ingredients

For the Milkshake

• 3 cups caramel ice cream
• 1/2 cup whole milk
• 2 oz dark rum (like Goslings or Myers's)
• 1/4 cup salted caramel sauce, plus more for drizzling

For Topping

• 1/2 cup heavy cream
• 1 tablespoon powdered sugar
• 1/4 teaspoon vanilla extract
• Flaky sea salt (like Maldon)

Instructions

1. Step 1: Place two glasses in the freezer for at least 15 minutes to chill. This keeps your milkshake cold longer.
2. Step 2: In a blender, combine 3 cups caramel ice cream, 1/2 cup whole milk, 2 oz dark rum, and 1/4 cup salted caramel sauce. Tip: If you want a thicker shake, use less milk; for a thinner one, add more.
3. Step 3: Blend on low speed until smooth, about 20-30 seconds. Don't over-blend or the ice cream will melt too much. Scrape down sides if needed.
4. Step 4: While the blender runs, make the whipped cream. In a medium bowl, whisk 1/2 cup heavy cream, 1 tablespoon powdered sugar, and 1/4 teaspoon vanilla extract until soft peaks form. You can also use a hand mixer for speed. Tip: Cold cream whips better—keep it chilled until ready.
5. Step 5: Pour the milkshake into the chilled glasses, leaving about an inch of room at the top.
6. Step 6: Top each milkshake with a generous dollop of whipped cream. Drizzle with extra salted caramel sauce and sprinkle with flaky sea salt. Serve immediately with a straw.

A sip of this milkshake delivers creamy caramel, a warm rum kick, and that perfect salty crunch. The flaky salt on top isn't just pretty—it makes every bite pop. If you're feeling extra, add a cinnamon stick as a stirrer for a cozy twist.
