Preheat the oven to 350 degrees F (175 degrees C).

Make the dough: Cut 1/2 cup butter into 1 cup flour using a knife or pastry blender. Add 1 tablespoon water (or as needed) and mix until crumbly, leaving pea-sized chunks. On a floured surface, roll dough out to 3 or 4 inches in width. Place onto a rectangular cookie sheet.

Make the filling: In a small saucepan over high heat, bring 1 cup water and 1/2 cup butter to a boil. Remove from the heat and stir in remaining 1 cup flour; mix until smooth. Beat in eggs, one at a time, mixing well after each addition. Stir in 1 teaspoon almond extract. Spread filling over dough.

Bake in the preheated oven for 55 to 60 minutes. The pastry will fall a little as it cools.

Meanwhile, make the icing: Combine confectioners’ sugar, cream, 1 tablespoon butter, and remaining 1 teaspoon almond extract.

Remove kringle from the oven and immediately spread icing over top.
