In a mixing bowl, combine almond flour, oat flour, melted coconut oil, beaten egg, honey, vanilla extract, salt, and baking powder. Mix until a dough forms.

Wrap the dough in plastic wrap and refrigerate for 15 minutes.

In another bowl, mix the protein powder and almond milk until smooth. Set aside.

Spread a thin layer of fruit jam on one half of the dough after rolling it out.

Roll out the chilled dough on a floured surface to about 1/8 inch thick.

Cut the dough into rectangles and place the filling on half of each rectangle.

Fold the other half over and seal the edges with a fork.

Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.

Place the assembled pop tarts on the baking sheet and bake for 15 minutes or until golden brown.

In a small bowl, mix powdered sugar, almond milk, and vanilla extract until smooth. Drizzle over cooled pop tarts.
