To prepare a streamline hungarian torte recipe, you'll first need to prepare the following ingredients: Preheat the oven to 375?F (190?C) and grease and flour two 9-inch tart pans. Set aside. Melt the butter in the saucepan over medium-low heat. Add the sugar and cook, stirring constantly, until the mixture is completely melted, about 5 minutes. Remove from the heat and add the egg yolks and vanilla. Beat the eggs with an electric mixer until stiff peaks form. Pour the batter into the prepared tart shells, filling each one-third of the way. Bake the tarts for 30 to 35 minutes, or until they are golden brown. Serve warm or at room temperature.
