Leave the grass-fed butter to soften at room temperature, or put it in the microwave on a low setting for 10 sec.
Put the butter and the cream cheese in a mixing bowl and beat with a hand mixer until creamy.
Wash the lemon in hot water, grate the zest into the cream and squeeze in about 1 tbsp of juice.
Add the yacon syrup and a pinch of salt and beat for 1 more min until fluffy.
Spoon the cream into two dessert bowls and chill for 20 min so the butter firms up slightly again.
Good to know
Butter for dessert? On a keto diet, definitely! This lemon cream tastes like the filling of lemon pralines.
Swaps
Lemon → orange (for a slightly sweeter, warmer citrus note, if your macros allow).
Cooking tips
Make sure all the ingredients are at room temperature. If the cream cheese is too cold, the butter seizes straight away and the cream turns unattractively lumpy.
Storage
In the fridge, the cream sets very firm. Take it out 15 minutes before eating so it softens.
