Vanilla Bean Frappuccino Sandwiches (Printable)

Soft coffee cookies paired with creamy vanilla bean ice cream for a refreshing summer indulgence.

# Ingredient List:

→ Coffee Cookies

01 - 1 1/2 cups all-purpose flour
02 - 1/2 cup unsalted butter, softened
03 - 1/2 cup light brown sugar
04 - 1/4 cup granulated sugar
05 - 1 large egg
06 - 2 tablespoons instant espresso powder
07 - 2 tablespoons hot water
08 - 1 teaspoon vanilla extract
09 - 1/2 teaspoon baking soda
10 - 1/4 teaspoon salt

→ Vanilla Bean Ice Cream

11 - 2 cups heavy cream
12 - 1 cup whole milk
13 - 3/4 cup granulated sugar
14 - 1 vanilla bean, split and seeds scraped, or 2 teaspoons vanilla bean paste
15 - 1/4 teaspoon salt

# Directions:

01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - Dissolve instant espresso powder in 2 tablespoons hot water. Set aside to cool to room temperature.
03 - In a mixing bowl, beat softened butter, light brown sugar, and granulated sugar together until light and fluffy, approximately 2-3 minutes. Add the egg and beat until fully incorporated.
04 - Mix the cooled espresso mixture and vanilla extract into the butter mixture until well combined.
05 - In a separate bowl, whisk together flour, baking soda, and salt. Gradually fold the dry ingredients into the wet mixture, stirring until just combined. Do not overmix.
06 - Scoop tablespoon-sized portions of dough onto prepared baking sheets, spacing them 2 inches apart. Gently flatten each portion with your hand.
07 - Bake for 10-12 minutes until set but still soft to the touch. Transfer cookies to a wire rack and cool completely.
08 - In a clean mixing bowl, whisk together heavy cream, whole milk, granulated sugar, vanilla bean seeds or paste, and salt until sugar dissolves completely.
09 - Transfer the ice cream base to an ice cream maker and churn according to manufacturer's instructions. Once churned, transfer to a freezer-safe container and freeze until firm, approximately 2 hours.
10 - Once cookies are completely cooled and ice cream is firm, scoop approximately 1/3 cup of ice cream onto the flat side of one cookie. Top with a second cookie and gently press to distribute the ice cream evenly.
11 - Wrap each sandwich individually in parchment or plastic wrap. Freeze for at least 1 hour before serving to achieve optimal texture.

# Expert Advice:

01 -
  • The coffee cookies are soft enough to bite through without shattering, but sturdy enough to hold creamy ice cream without falling apart.
  • You get that café-inspired flavor combination without needing an espresso machine or complicated equipment.
  • They're impressive enough to serve at gatherings but honestly simple enough to make on a whim when the heat hits.
02 -
  • Room temperature ingredients make a huge difference—cold eggs and butter won't blend smoothly, and your dough will be lumpy and sad instead of creamy and cooperative.
  • Don't overbake the cookies; they should look slightly underdone when you pull them out because they continue cooking on the hot pan and firm up as they cool, which keeps them tender enough to bite through with ice cream inside.
03 -
  • Always use real vanilla bean paste or an actual vanilla bean instead of extract if you can manage it; the difference is noticeable and worth the tiny extra cost for something as simple as ice cream.
  • Chill your ice cream maker bowl for at least 24 hours before churning—a truly cold base freezes faster and creates a smoother, denser texture that holds together better in the sandwich.
