Mini Treacle Tarts

Sue Peterson
These gluten-free mini tarts could easily have been served at Slughorn's Christmas party since they're a great grab-and-go item. They're also good for snacking on lazy fall days.

Ingredients
  

Treacle Filling

  • 4 gluten-free hamburger buns
  • 1 cup corn syrup light
  • 1 cup corn syrup dark
  • 3 lemons juiced and zested

Tart Dough

  • 2 1/4 cups gluten-free flour
  • 1 cup powdered sugar
  • 1/2 tsp. salt
  • 1 cup butter cubed, cold
  • 1/3 cup heavy cream cold
  • 2 egg yolks cold
  • 1 tsp. vanilla extract

Egg Wash

  • 1 tsp. water
  • 1 egg

Instructions
 

Treacle Filling

  • Break the gluten-free hamburger buns into crumbs by hand or with a food processor.
  • In a large bowl, mix together crumbs and corn syrups.
  • Add lemon juice and zest to filling and mix well.
  • Pour filling into a large zipper bag or piping bag. Allow to sit in refrigerator at least until firm, ideally overnight.

Tart Dough

  • Whisk together flour, powdered sugar, and salt into mixing bowl. Add cubed butter.
  • Use paddle on low speed to break up butter cubes until mixture resembles course crumbs.
  • In seperate bowl, beat together egg yolks, cream, and vanilla extract.
  • Pour liquid ingreidents into mixer over dry ingredients. Mix only until liquid is incorporated; be careful not to overmix. If the dough is dry, add 1 tsp. heavy cream at a time.
  • Divide dough into thirds, shape into disks, wrap in plastic, and refrigerate for at least 2 hours.
  • Roll out dough on a floured surface to about 1/8" thick. Cut out rounds using 2 3/4" cutter.
  • Grease mini cupcake pans with preferred cooking spray.
  • Do not push the rounds into the molds. Instead, place the dough over the cavity and turn the dough using four fingers positioned on the outside rim of the round. Do this until dough stretches into the cup. Once the dough is mostly in the pan, push with fingertips carefully to fill the corners.
  • Making 48 tarts will use about three-quarters of the dough. Return remaining dough to refrigerator until it's needed to top tarts.

Egg Wash

  • Beat egg and water together until smooth. Set aside.

Assembly

  • Preheat oven to 400°F.
  • Fill tarts with treacle filling almost to top and level filling so that it's flat.
  • Roll out the remaining dough as before. Tops can be either lattice or any shape for which a cutter is available.
  • Brush tops of tarts with egg wash and cover with top crust.
  • Bake tarts about 15–20 minutes, or until lightly brown.
  • After tarts are cool, remove from pan by placing four fingers at the 2, 4, 8, and 10 positions and gently twist to loosen. Then, use a knife to remove each tart from pan.

Notes

  • A similar gluten-free bread product can be substituted for the hamburger buns if desired.
  • Golden syrup can be substituted for the two corn syrups if desired.
  • The tart dough can stay refrigerated for up to three days. Freeze it if you're keeping it any longer.
  • Gluten-free pie doughs tend to be drier than wheat flour doughs, meaning they are more likely to crack while shaping. Be careful when handling this dough.
  • Be careful not to get the filling outside of the shells. It will make them very hard to remove from the pan.
