Gluten-Free Cowberry Almond Tart with Crisp Crust Delight
Cowberry Tart
Low-sugar gluten-free cowberry pie with almond crust—bright, tart, and pleasantly nutty.
Nutrition (per serving)
This cowberry tart is one of those joyful, slightly tart desserts that feels both homey and a little special. I love the way the bright cowberries (think lingonberries) sing against a tender almond-based crust — it’s naturally gluten-free and keeps sugar low without skimping on flavor.
It’s perfect for sharing: the crust is simple to make ahead, the filling comes together in minutes, and the finished pie is balanced and fresh — nutty, lemony, and lightly sweet. Serve it slightly warm with a dollop of yogurt or whipped cream for a lovely contrast.
Ingredients
- Almond flour (blanched):2 cups
- Tapioca starch (for crust):3 tbsp
- Granulated erythritol (or coconut sugar):2 tbsp
- Cold unsalted butter, diced:4 tbsp
- Large egg:1 piece
- Vanilla extract:1 tsp
- Salt:1/4 tsp
- Cowberries (fresh or frozen):3 cups
- Granulated sugar (or 2 tbsp honey):2 tbsp
- Tapioca starch (for filling):2 tbsp
- Lemon juice:2 tbsp
- Lemon zest:1 tsp
- Water:2 tbsp
- Egg (for egg wash):1 piece
- Slivered almonds (optional sprinkle):2 tbsp
Instructions
-
Preheat the oven to 350°F. Grease a 9-inch tart pan with removable bottom and set aside.
-
Make the crust: in a bowl combine almond flour, 3 tbsp tapioca starch, erythritol, and 1/4 tsp salt. Cut in the cold diced butter with a fork or pastry cutter until mixture resembles coarse crumbs.
-
Add 1 beaten egg and 1 tsp vanilla to the flour mixture and stir until a soft dough forms. Press the dough evenly into the bottom and up the sides of the tart pan.
-
Chill the crust in the freezer for 10 minutes to firm up slightly, then blind-bake for 12-15 minutes until just golden. Remove and set aside to cool slightly.
-
While crust bakes, prepare the filling: in a saucepan combine cowberries, 2 tbsp sugar, 2 tbsp tapioca starch, lemon juice, lemon zest, and 2 tbsp water. Stir to combine.
-
Cook the filling over medium heat, stirring frequently, until the berries release juice and the mixture thickens, about 6-8 minutes. Taste and adjust sweetness if desired.
-
Pour the hot cowberry filling into the pre-baked crust, spreading it evenly. Brush the crust edge with a beaten egg for shine and sprinkle slivered almonds over the filling if using.
-
Return the tart to the oven and bake for 12-15 minutes more, until filling is bubbling and crust is golden brown.
-
Let the tart cool on a rack for at least 1 hour (the filling firms as it cools). Serve slightly warm or at room temperature with a spoonful of Greek yogurt or light whipped cream.
-
Store leftovers covered in the refrigerator for up to 3 days.
Tips & Notes
- If using frozen cowberries, thaw and drain excess liquid before cooking so the filling isn’t too watery.
- For a nut-free version, substitute the almond flour crust with a gluten-free oat and butter crust (use certified gluten-free oats).
- Keep sugar low by using erythritol or a small amount of maple syrup; lemon juice brightens the berries and reduces the need for added sugar.
- Make the crust ahead and freeze it pressed in the pan — fill and bake on the day you want to serve.
