Pistachio cake

2 cups (260g) unsalted pistachios (out of shells)

2 and 1/3 cups (275g) wholemeal flour

2 teaspoons baking powder

1/2 teaspoon baking soda

1 teaspoon salt

3/4 cup (12 Tbsp; 170g) unsalted butter, softened to room temperature

1 and 3/4 cups (350g) granulated sugar

5 large egg whites, at room temperature

1/2 cup (120g) sour cream, at room temperature*

2 teaspoons pure vanilla extract

1 teaspoon almond extract

1 cup (240ml) whole milk, at room temperature*

Preheat oven to 350°F (177°C). Grease three 8-inch round cake pans, line with parchment paper rounds, then grease the parchment paper. Parchment paper helps the cakes seamlessly release from the pans. (If it’s helpful, see this parchment paper rounds for cakes video & post.)

Make the cake: Pulse the pistachios in a food processor until ground up into very fine crumbs. See photo above for a visual. 

Pour 1 and 1/2 cups (180g) of pistachio crumbs in a large bowl. (Reserve the remaining pistachio crumbs for garnish.) Whisk in the cake flour, baking powder, baking soda, and salt. Set aside.

Using a handheld or stand mixer fitted with a paddle or whisk attachment, beat the butter and sugar together on high speed until smooth and creamy, about 3 minutes. Scrape down the sides and bottom of the bowl with a rubber spatula as needed. Beat in the egg whites on high speed until combined, about 2 minutes. Beat in the sour cream, vanilla extract, and almond extract. Scrape down the sides and bottom of the bowl as needed. Add the dry ingredients, then start the mixer on low speed. With the mixer running, slowly pour in the milk (and the green food coloring, if using) and mix just until combined. You may need to whisk it all by hand to make sure there are no lumps at the bottom of the bowl. The batter will be slightly thick.

Bake in bundt tin for 55 mins
