Prepare Your Condensed Milk: First, you'll need to prepare your Keto Condensed Milk following its specific recipe. This is best done the day before and allowed to cool completely in the fridge. If you're short on time, you can find a quick substitution tip in the original recipe if needed!
Toast the Almond Base: In a dry, hot non-stick pan or skillet, gently toast the almond flour over medium heat for 5 to 8 minutes, stirring often, until it's lightly golden and wonderfully fragrant. This step really boosts the flavor! Transfer it to a bowl and let it cool down completely (you can pop it in the freezer to speed this up).
Mix the Base Crumble: Once the almond flour is cool, add the melted butter, powdered low-carb sweetener, cinnamon, and sea salt. Mix everything together with a fork or your hands until it forms a lovely crumbly texture. Set this aside.
Whip the Creamy Filling: In a large bowl, combine the heavy whipping cream, mascarpone (or cream cheese), and your chilled Keto Condensed Milk.
Create Stiff Peaks: Using a hand blender or stand mixer, beat the mixture until stiff peaks form – it should be thick and hold its shape.
Add Zest & Juice: Gently fold in the fresh lime juice and finely grated lime zest. If you like, add a few drops of natural green food coloring to get that vibrant lime hue. Mix until everything is just combined and smooth.
Assemble Your Cups: Divide the almond crumble base evenly among 8 small jars or dessert cups (each about 1-cup capacity).
Layer with Lime Cream: Spoon the creamy lime layer over the almond base in each jar. To keep it tidy, start with 2 generous tablespoons per jar, then distribute any remaining mixture.
Whip the Topping: In a separate bowl, whip the remaining 1/2 cup of heavy whipping cream until soft peaks form. Dollop a spoonful of this whipped cream onto the top of each lime cup.
Garnish & Chill: For a final touch, sprinkle with extra finely grated lime zest and add a small lime slice to each cup. Enjoy immediately for a fresh treat, or chill in the refrigerator for up to 5 days. Covering them with cling film helps keep them fresh!
