Place the white chocolate and milk in a small microwave-safe bowl and heat at half power for 30 seconds. Stir and then continue microwaving in 10 second increments, stirring after each one, until completely melted.
1/4 cup (43 grams) white chocolate chips, 2 tablespoons milk
In a small bowl, beat the cottage cheese, honey, and cream cheese using an immersion blender. You could also use a mini food processor. Process until completely smooth and no chunks of cottage cheese remain.
1/2 cup (118 ml) cottage cheese, 2 teaspoons honey, 2 ounces (57 grams) cream cheese
Add the white chocolate mixture and mix until smooth. Scrape the sides of the bowl as needed.
Put the graham cracker or cookie crumbs at the bottom of a small serving glass and use a shot glass to press them down. Spoon the mousse over the top.
1 graham cracker
Serve immediately (it'll be quite soft) or refrigerate for 30 minutes to an hour or until slightly firmer.
