These classic Vienna Bars, once a favorite at the Reagan White House, feature a buttery shortbread crust, a rich raspberry and chocolate layer, and a fluffy meringue topping with toasted nuts. Elegant and nostalgic, they’re perfect for special gatherings or holiday trays.
Preheat oven to 350°F and prepare a 9x13-inch baking dish.
In a large bowl, cream together softened butter and 1/2 cup sugar until light and airy, about 2 minutes. Mix in egg yolks one at a time.
Gradually mix in salt and flour until a soft dough forms. Press evenly into the prepared baking dish to form a crust.
Bake crust for 13–15 minutes, or until lightly golden at the edges.
Meanwhile, beat egg whites in a clean bowl with a hand mixer until stiff peaks form. Gradually add 1/2 cup sugar and continue beating until glossy stiff peaks form again. Fold in chopped nuts gently.
Spread raspberry jam over the warm crust. Sprinkle with chocolate chips, if using.
Carefully spread the meringue mixture over the jam layer, smoothing to the edges.
Return pan to oven and bake for 18–20 minutes, or until the meringue is just lightly golden.
Let cool for 10–15 minutes, then slice into bars. Allow to cool completely before removing from pan for clean edges.
Notes
These bars can be made a day in advance and stored in an airtight container. For a nuttier texture, lightly toast the nuts before folding into the meringue.
