Gluten-Free Pumpkin Pie Streusel Bars

By

NOTES:
* To make oat flour, pulse quick or rolled oats in a food processor or coffee grinder until finely ground.
** If you don't have pumpkin pie spice on hand, make your own using 1 teaspoon cinnamon, 3/4 teaspoon ginger, 1/2 teaspoon allspice, and 1/4 teaspoon nutmeg.

Ingredients

  • For the crust and topping:
  • 1 1/4 cups certified gluten-free oat flour*
  • 2 cups certified gluten-free rolled oats
  • 1 tablespoon cinnamon
  • 1 cup brown sugar
  • 1/4 teaspoon salt
  • 3/4 cup + 2 tablespoons unsalted butter, melted and cooled slightly
  • For the filling:
  • 1 15-ounce can pumpkin puree
  • 2 large eggs
  • 1/3 cup granulated sugar
  • 1/3 cup brown sugar
  • 2 1/2 teaspoons pumpkin pie spice**
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt
  • 1/2 cup evaporated milk
  • Salted Maple Caramel Sauce:
  • 1/4 cup unsalted butter
  • 1/2 cup brown sugar
  • 1/4 cup whipping cream or heavy cream
  • 1/4 cup Grade B maple syrup
  • 1/8 - 1/4 teaspoon salt (I used 1/4 teaspoon)

Preparation

Step 1

1. Preheat the oven to 350∞F. Line an 8" x 8" pan with parchment paper and set aside.

2. Prepare the crust and topping. In a large mixing bowl, stir together the oat flour, oats, cinnamon, sugar and salt. Stir in the butter until well combined.

3. Pat half of the mixture firmly onto the bottom of the prepared pan.

4. Bake for 18-22 minutes or until lightly golden brown. The crust will bubble a little during baking.

5. Let the crust cool for 5-10 minutes while preparing the filling.

6. In a large mixing bowl, stir together all the filling ingredients. Pour evenly over the crust and bake for 12 minutes.

7. Remove from the oven and add walnut-sized pieces of the remaining oat mixture over the filling. It will be a very thick layer and some of it will sink a little into the filling. Bake for another 30 minutes or until the filling is golden brown and firm and the middle is set.

8. Let cool for 1 hour and serve with whipped cream or maple caramel sauce.

Cool completely before covering. Store at room temperature for up to 2 days or in the refrigerator for up to 4 days.

For the sauce:
In a small saucepan over medium heat, melt the butter. Stir in the brown sugar until combined. Add the cream and mix until fully combined, and continue stirring until the mixture comes to a boil. Continue boiling and stirring until it thickens enough to coat the back of a spoon, about 2-5 minutes.

Turn off the heat, remove the pan from the burner, and add the maple syrup and salt (start off with ⅛ teaspoon and add more to taste). Stir until completely incorporated and the salt has dissolved. Use immediately or let cool completely before covering and refrigerating.

Refrigerate for up to 1 week. Before serving, stir to reincorporate the maple syrup and reheat in the microwave at half power for 10-15 seconds or until warm enough for your liking.
