Heat your oven to 350°F (175°C). Combine sugar and cinnamon in a small bowl. Grease two loaf pans and coat the insides with the cinnamon-sugar blend.

Grab a big bowl and toss in the cake mix, pudding mixes, eggs, sour cream, oil, and water. Stir it all up until you've got a smooth, thick batter.

Evenly divide the batter between the prepared loaf pans. Spread it out smoothly on top with a spatula.

Bake for about 45 minutes or until a toothpick stuck in the middle comes out clean. Let cool in the pans for 10 minutes, then carefully remove and place on a wire rack to finish cooling.

Stir together the powdered sugar, melted butter, almond, and vanilla extracts in a medium bowl. Add a little milk at a time until the glaze is just right—thick enough to drizzle but not runny.

When the bread is cool, pour the glaze over both loaves. Sprinkle the pistachios on right after so they stick. Let it sit until the glaze hardens before cutting a slice.
