1 1/3 cup tapioca flour
1/2 tsp kosher salt
1/4 tsp baking soda
6 Tbsp butter, melted
1/3 cup maple syrup
2 tsp vanilla extract
1 large egg
2/3 cup strawberry preserves
1 cup powdered sugar (if using sugar substitute, do 1/2 substitute and 1/2 real)
2 Tbsp almond milk
1/2 tsp vanilla extract
1 Tbsp rainbow sprinkles
Preheat oven to 350. Line 9x9 baking pan with parchment paper and spray with nonstick spray. In a large bowl, add almond flour, tapioca flour, salt, and baking soda. Whisk to combine until there are no lumps. Add melted butter, maple syrup, vanilla, and egg. Stir until well combine and a dough forms. Transfer half of the dough into prepared pan and press into an even layer. Next, spread strawberry preserves onto base and spread into an even layer. Take two sheets of parchment paper about 10x10 each. Place first sheet on counter and place remaining dough in center. Top with second piece of parchment paper and use a rolling pin to roll the dough into a 9x9 square. The parchment paper/rolling pin is necessary as dough will likely be very sticky and difficult to shape. Gently slide the rolled dough with the bottom sheet of parchment paper off the counter and carefully flip on top of the jam. Gently press down on the edges until most of the jam is covered. Bake for 20 minutes until the top is golden brown. Remove from oven and let cool in the pan for at least an hour. Once cooled, transfer to a baking rack to finish cooling. In a medium bowl, whisk together powdered sugar, almond milk, and vanilla. You may have to adjust amount of almond milk to get to a spreadable consistency. Once bars are completely cooled, add frosting, spreading with a spatula and top with sprinkles. Place in fridge and allow frosting to harden, at least 15 minutes.
