I’m pretty sure I’m the reason my sister started drinking London Fog lattes in the first place. Big sister influence is powerful, thankless work. Years later, she’s an Earl Grey ice cream person, and I’m choosing to take full credit for her excellent taste.
These London Fog Ice Cream Sandwiches are the logical conclusion: deeply bergamot-scented Earl Grey ice cream tucked between soft brown sugar vanilla cookies. They’re creamy, chewy, floral without tasting like perfume, and just unusual enough to make a freezer full of them feel like a minor accomplishment.
Why You’ll Love These London Fog Ice Cream Sandwiches
- The Earl Grey actually tastes like Earl Grey. Six tea bags may look aggressive, but cold temperatures mute flavor. We are not going through all this trouble for vaguely bergamot-adjacent vanilla ice cream.
- The cookies stay soft in the freezer. Brown sugar, an extra egg yolk, and a slight underbake give them a chewy texture instead of turning them into something suitable for skipping across a pond.
- They feel genuinely special. Homemade ice cream sandwiches already have dinner-party energy. Add Earl Grey and suddenly everyone assumes you have your life together.
- You can make them ahead. Once assembled, they’re waiting in the freezer whenever dessert is required.
The Secret to Strong Earl Grey Ice Cream
Earl Grey gets its distinctive citrusy-floral flavor from bergamot, and that aroma is exactly what makes a London Fog so good. The problem is that freezing dulls flavor. An ice cream base that tastes perfectly tea-forward while warm can become surprisingly shy once frozen.
That’s why this custard uses six Earl Grey tea bags and a relatively short, controlled steep. You want a confident tea flavor without extracting enough tannin to make the cream bitter. Gently press the bags before removing them, but don’t wring them out like tiny laundry.
Auntie Duck has standards. We do not serve pond water.
Why Brown Sugar Cookies Work Better Here
The cookie might secretly be the most important part of a homemade ice cream sandwich. A perfectly crisp room-temperature cookie can become a dental event after a few hours in the freezer.
These are intentionally soft. Brown sugar adds moisture and a subtle caramel flavor that works beautifully with vanilla and bergamot, while the extra egg yolk adds richness and tenderness. Pull the cookies when the edges are set but the centers still look a little underdone. They’ll finish setting as they cool and stay much more pleasant to bite once frozen.
Tips, Tricks & Variations
Choose a bold Earl Grey. This isn’t the moment for a tea that whispers bergamot from another room. A strongly aromatic Earl Grey gives you the best flavor after freezing.
Don’t skip the custard chill. A thoroughly cold base churns faster and develops smaller ice crystals, which means smoother ice cream.
Cut the ice cream instead of scooping it. Freezing the churned ice cream in an even layer lets you cut tidy rounds that sit beautifully between the cookies. There is significantly less frantic smooshing involved.
Add a dark chocolate edge. Finely chopped bittersweet chocolate gives the sandwiches a little crunch and plays extremely well with bergamot. It’s optional, but highly recommended if you enjoy gilding the lily. Or feathering the duck. We’re committed now.
Try a lemony version. A little finely grated lemon zest in the cookie dough will amplify Earl Grey’s citrus notes without turning these into lemon ice cream sandwiches.
How to Store Homemade Ice Cream Sandwiches
Wrap each sandwich individually once assembled, then store them together in an airtight freezer container. The individual wrapping protects the cookies from drying out and keeps the ice cream from picking up mysterious freezer flavors.
For the best texture, let a sandwich sit at room temperature for about 3 to 5 minutes before eating. You want the ice cream just beginning to soften around the edges while the cookie becomes perfectly chewy.
London Fog Ice Cream Sandwich FAQ
What does London Fog taste like?
A classic London Fog combines Earl Grey tea with milk and vanilla, giving it a creamy flavor with citrusy, floral bergamot notes. These ice cream sandwiches use that same combination, then add brown sugar cookies for a buttery caramel note.
Why are there six Earl Grey tea bags in the ice cream?
Cold temperatures make flavors seem less intense, so the custard needs a pronounced Earl Grey flavor before it goes into the freezer. Six tea bags provide enough bergamot to remain noticeable without requiring a long steep that could make the ice cream bitter. Also, Auntie Duck would expect better.
Can I make the ice cream sandwiches ahead of time?
Absolutely. They’re actually better after an hour or two in the freezer because the cookies and ice cream settle into one glorious little unit. Keep them individually wrapped in an airtight container and let them soften for a few minutes before serving.
Consider these London Fog Ice Cream Sandwiches the natural consequence of years of irresponsible big-sister influence. You’re welcome, Duck.
London Fog Ice Cream Sandwiches
Ingredients
Earl Grey Ice Cream
- 2 cups heavy cream
- 1 cup whole milk
- 6 Earl Grey tea bags preferably strongly bergamot-forward
- 5 large egg yolks
- 2/3 cup granulated sugar
- 1 tablespoon light corn syrup
- 1 teaspoon vanilla extract
- 1/4 teaspoon kosher salt
Soft Brown Sugar Cookies
- 1/2 cup unsalted butter softened
- 3/4 cup packed light brown sugar
- 1/4 cup granulated sugar
- 1 large egg
- 1 large egg yolk
- 2 teaspoons vanilla extract
- 1 3/4 cups all-purpose flour
- 1/2 teaspoon baking soda
- 3/4 teaspoon kosher salt
Optional Chocolate Edge
- 3 ounces bittersweet or semisweet chocolate very finely chopped
Instructions
- Combine the heavy cream and milk in a saucepan and heat until steaming but not boiling. Remove from the heat, add the Earl Grey tea bags, cover, and steep for 10 minutes.
- Gently press the tea bags against the side of the pan, then remove them without aggressively squeezing.
- Whisk the egg yolks, granulated sugar, and corn syrup in a bowl until smooth. Slowly whisk in about 1 cup of the warm Earl Grey cream, then pour the mixture back into the saucepan.
- Cook over medium-low heat, stirring constantly, until the custard reaches 170 to 175°F and lightly coats the back of a spoon.
- Strain the custard through a fine-mesh sieve, then stir in the vanilla and salt. Chill completely, preferably overnight.
- Churn the chilled custard according to your ice cream maker’s instructions. Spread the freshly churned ice cream about 3/4 inch thick in a parchment-lined 8-inch square pan and freeze until completely firm, at least 4 hours.
- Heat the oven to 350°F and line two baking sheets with parchment paper.
- Beat the softened butter, brown sugar, and granulated sugar until creamy. Beat in the egg, egg yolk, and vanilla.
- Add the flour, baking soda, and salt and mix just until no dry flour remains.
- Divide the dough into 16 equal portions, about 2 tablespoons each. Roll into balls, gently flatten, and arrange on the prepared baking sheets.
- Bake for 8 to 10 minutes, until the edges are set but the centers still look slightly underdone. Cool on the baking sheets for 5 minutes, then transfer to a rack and cool completely.
- Use a round cutter approximately the same diameter as the cookies to cut 8 thick rounds from the frozen Earl Grey ice cream.
- Sandwich each ice cream round between two cookies and press very gently. If using the chocolate, roll the exposed ice cream edges in the finely chopped chocolate.
- Wrap the sandwiches individually and freeze for at least 1 to 2 hours before serving. Let stand at room temperature for 3 to 5 minutes before eating.
