Set your oven to 350°F (175°C). Use cooking spray or oil to grease two loaf tins. Stir together the cinnamon and sugar in a bowl, then dust the insides of the pans evenly with the mix, making sure to cover all sides and the base.

Get a large bowl and combine the cake mix, pudding mix, eggs, oil, water, and sour cream. Stir until you’ve got a smooth, thick batter.

Scoop the batter into the two prepared loaf tins, dividing it evenly. Spread it out neatly with a spatula so it’s smooth on top.

Pop the pans into your heated oven and bake for about 45 minutes. Use a toothpick to check—they’re done if it comes out clean. Let them rest in the pans for 10 minutes, then gently turn them out onto a wire rack to let them cool fully.

In a bowl, mix the powdered sugar, butter, almond flavoring, and vanilla flavoring. Slowly add milk, mixing well as you go, until it’s thick like syrup but still loose enough to drizzle.

When the loaves are cool, spoon the icing over the tops. While it’s still wet, scatter the crushed pistachios over it. Let the icing firm up before slicing and serving.
