the fresh blueberry sauce

I wanted to keep the freshness of the blueberries. To do this, I divided the blueberries and used 1/3 of them for making the sauce. The blueberry sauce takes only about three minutes to cook. Once the sauce is ready, stir in the remaining fresh blueberries, and the topping is prepared.

Key Lime Pie Version

To make this gluten-free key lime dessert into a pie, follow the same directions except using a deep dish-style pie plate.  You may have to adjust the baking time probably by about 3 – 5 minutes longer. The gluten-free key lime pie comes out spectacular!

Ingredients

CRUST
2 cups (224 g)blanched almond flour
3 Tbsp. Coconut sugar or sweetener of choice
1/2 tsp. GF ground cinnamon
1/2 tsp. Sea salt
1/4 cup unsalted butter, melted 
1 large egg
CUSTARD LAYER
5 large egg yolks
1 3/4 cups sweetened condensed milk
2/3 cup lime/lemon juice. (I used half lime and half lemon juice), if you can get key limes, use key lime juice
2 tsp. Lime zest
BLUEBERRY TOPPING
3 cups fresh blueberries, divided
1/2 cup water or fruit juice
2 tsp. lime juice
2 Tbsp. Coconut sugar or sweetener of choice
1/2 tsp. Pure vanilla extract
1 Tbsp. Tapioca flour/starch

Instructions

  1. Preheat oven to 350 F
  2. CRUST
  3. In a food processor, pulse the dry ingredients. Add melted butter and egg and pulse just to combine. 
  4. Using a spatula, evenly spread the mixture on the bottom of an 8-inch non-stick springform pan. Using a fork, poke a few holes in the crust. Place the pan on a baking tray and bake for 10 minutes
  5. CUSTARD LAYER
  6. Meanwhile, whisk the egg yolks until smooth. Add the sweetened condensed milk, lime zest, and lime/lemon juice. Whisk to combine. Pour the mixture into the baked crust
  7. Bake for 20 - 25 minutes, until just set on top. Set aside for 20 minutes to cool slightly
  8. BLUEBERRY TOPPING
  9. While the cake is cooling, prepare the topping. In a medium saucepan, whisk together water with juice, sweetener, vanilla and tapioca flour/starch. Cook over medium-low heat until the sauce starts to thicken. Stir in 1 cup of blueberries and cook until they begin to burst—about 3 minutes.
  10. Remove the saucepan from the stove and stir in the remaining blueberries
  11. Pour the topping evenly over the cake, then cover and chill in the fridge until set, at least 2 - 4 hours or overnight
  12. Using a knife, cut around the cake edges, then remove the cake from the springform pan
