Rhubarb-Pistachio Bundt Cake With Rose Glaze

Preparation

1. Make the cake:

   Step 1

   Preheat oven to 350°F. Butter and flour Bundt pan, tapping out excess flour.

   Step 2

   Rub together granulated sugar and lemon zest with your fingers in a large bowl until fragrant. Using an electric mixer on medium speed, cream lemon sugar and 3/4 cup butter until light and fluffy, about 4 minutes. Add eggs 1 at a time, scraping down sides of bowl and beating well between each addition. Beat in rose water and vanilla extract on medium-low speed until just combined.

   Step 3

   Whisk 2 1/4 cups flour, salt, baking powder, and baking soda in another large bowl. With mixer on low, add dry ingredients to lemon sugar mixture in 3 additions, alternating with yogurt in 2 additions, beginning and ending with dry ingredients, scraping down sides and bottom of bowl as needed. Fold in pistachios.

   Step 4

   Cut rhubarb crosswise into 2 1/2" pieces. Using a mandoline set to 1/4" or a very sharp knife, slice rhubarb lengthwise, maintaining as much red skin on stalks as possible.

   Step 5

   Pour one-third of the batter into prepared pan and smooth surface. Add half of the rhubarb, nestling pieces side by side to form a thick ring on top of batter. Pour another third of the batter on top of rhubarb layer; smooth surface. Repeat with remaining rhubarb and batter.

   Step 6

   Bake cake until the surface is cracked and golden brown, springs back to the touch, and a tester inserted into the center comes out clean, 50–60 minutes. Let cake rest in pan 10 minutes, then turn out onto a cooling rack.

2. Make the rose glaze:

   Step 7

   Whisk powdered sugar, milk, rose water, vanilla extract, and salt in a medium bowl until well combined. Glaze should be pourable but stiff enough to hold its shape-it can be thickened with more powdered sugar or thinned with more milk if needed.

3. Decorate the cake:

   Step 8

   Using a spoon, drizzle rose glaze over cooled cake, holding the spoon a few inches above the cake. While glaze is still wet, sprinkle rose petals and pistachios on top.

4. Do Ahead

   Step 9

   Cake can be baked, cooled, wrapped in plastic, and stored at room temperature up to 3 days. Glaze can be made and stored in an airtight container at room temperature up to 5 days.
