Ingredients You’ll Need

For the Crust (Makes 12 Mini Tarts):

  • 1 1/2 cups almond flour
  • 1/4 cup coconut flour
  • 1/4 tsp salt
  • 1/2 cup cold butter, cubed
  • 1 egg yolk
  • 1 tsp vanilla extract

Optional: Use store-bought keto or gluten-free tart shells to save time.

For the Filling:

  • 1/2 cup unsalted butter, melted
  • 1/3 cup powdered erythritol or monk fruit sweetener
  • 1/4 cup heavy cream or coconut cream
  • 1/4 cup golden syrup alternative (like Lakanto Golden or allulose syrup)
  • 1/4 tsp salt
  • 1 tsp vanilla extract
  • 1/4 tsp cinnamon (optional, for warmth)
  • 1/4 cup chopped pecans or walnuts (optional)

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C) . Grease a mini muffin tin or use pre-made tart shells.

Step 2: Make the Crust (Optional DIY)

In a mixing bowl, combine:

  • Almond flour
  • Coconut flour
  • Salt

Cut in cold butter using a pastry cutter or fork until mixture is crumbly.

Add egg yolk and vanilla, then press the dough into a mini muffin tin or tart pan.

Pierce the bottom with a fork and bake for 10–12 minutes , or until lightly golden. Set aside to cool slightly.

Tip: If using store-bought shells, skip this step!

Step 3: Prepare the Filling

In a medium bowl, whisk together:

  • Melted butter
  • Powdered sweetener
  • Heavy cream
  • Golden syrup alternative
  • Salt
  • Vanilla
  • Cinnamon (if using)

Stir well until smooth and fully combined.

Optional: Fold in chopped nuts for extra crunch and texture.

Step 4: Fill the Tart Shells

Pour the filling evenly into each cooled tart shell—fill almost to the top.

Place the muffin tin back in the oven and bake for 18–22 minutes , or until the filling is set around the edges but still slightly jiggly in the center.

Let cool completely before removing from the tin—the filling firms up as it cools.

Step 5: Serve and Enjoy!

Serve chilled or at room temperature.

Description

Indulge in these sweet, gooey, and buttery delights, guilt-free!


Ingredients

🥜 1 3/4 cups (196 g) almond flour
🍬 3 tbsp (18.26 g) Swerve Confectioners
🧂 1/2 tsp xanthan gum
🧂 1/4 tsp salt
🥚 1 large egg
🧈 3 tbsp (42.61 g) butter, melted
🧈 1/4 cup (56.75 g) unsalted butter
🍬 1/3 cup (60.67 g) Swerve Brown
🍬 1/3 cup (66.67 g) allulose (or BochaSweet)
🥛 1/2 cup (118.29 ml) heavy whipping cream
🍬 1/2 tsp caramel extract (or vanilla extract)
🧂 1/4 tsp xanthan gum
🧂 1/8 tsp salt
🥚 1 large egg, room temperature
🍇 2 tbsp raisins, chopped (or chopped pecans or walnuts)


Instructions

Preheat the oven to 325ºF and lightly grease a non-stick muffin pan. In a large bowl, whisk together the almond flour, powdered sweetener, salt, and xanthan gum. Stir in the egg and melted butter until the dough comes together. Split the dough into two portions. Dust a work surface lightly with more almond flour and transfer one portion of the dough to the work surface. Cover the dough with waxed paper or parchment paper and roll out to an even 1/8″ thickness. Cut out into 3½ inch circles (cookie or biscuit cutters work, as does a drinking glass). Use an offset spatula to carefully lift each crust off the work surface. Press the crusts carefully down into the prepared muffin cups. If they crack at all, use a little extra dough to patch the crack. Repeat with the other half of the dough, then gather the scraps and re-roll to get more circles. You should be able to get at least 12 crusts. Bake the crusts for 12 minutes, then remove and let cool completely to firm up. Combine the butter and sweeteners in a medium saucepan over medium heat. Bring to a boil and cook for 3 to 5 minutes, watching carefully to make sure it doesn’t burn. Remove from heat and add the heavy cream and caramel extract. (The mixture will bubble vigorously, this is normal). Sprinkle the surface with the xanthan gum and whisk vigorously to combine. Whisk in the salt. Let cool to lukewarm, about 10 minutes. Once cooled, whisk in the egg. Divide the chopped raisins or pecans among the tart shells and spoon the filling over top. Fill each crust almost all the way to the top. Bake for 15 to 20 minutes, until the tart edges are golden and the filling is mostly set with a little jiggle in the center (it should still look a little wet in the very center of each tart). Remove from oven and let cool completely, then use a knife to loosen each tart.
