Low carb tarts are filled with smooth mascarpone and topped with a blueberry sauce to make a creamy yet light low carb and gluten free dessert. A tart that is creamy but still light and refreshing.
The sweet delicate pastry with the mascarpone cream filling makes a delicious summer treat. The touch of lemon in the mascarpone gives it a slight tart flavour and stops it being too sweet. The blueberry topping is the perfect addition for the creamy tart.
The beauty of these blueberry mascarpone tarts is that they are simple to make but look elegant. They could happily match a store-bought dessert yet are a healthier option. I find that this is a great dessert for dinner parties and holidays. The bulk of mine were taste tested at my art class, so they can be enjoyed at any event! You could use other berries for the topping for a berry keto dessert.
The low carb pastry is a delicate melt in your mouth treat made with almond flour. The addition of an egg makes this a rich dessert pastry, perfect for a light creamy filling. I’ve used this pastry in other desserts and it has not yet disappointed me.
HOW TO MAKE LOW CARB TARTS
What you need:
- Mini tart cases, preferable 4 inch ones. I used silicone mini tart cases but you could use tin ones with a removable bottom.
- Almond flour, butter, egg, vanilla extract and ground low-carb sweetener. I used erythritol and ground it with my coffee bean grinder.
- Mascarpone cheese, whipping cream, low carb sweetener and lemon juice. I use erythritol for the sweetener.
- Blueberries for the topping. I used blueberries but other berries would be just as delicious.
HOW TO MAKE LOW CARB PASTRY
The almond flour pastry is made in a food processor as I find it combines well. You could mix the ingredients in a bowl but you need to blend them very thoroughly as you are looking for a rich, slightly stick pastry.
The pastry is pressed into the tart cases rather than rolled. Many low carb pastry doughs are too sticky or delicate to roll out. When you press the pastry into tin, try to get an even as possible coverage.
