Preheat oven to 350 degrees. Grease which ever sized pans you are using. Makes 2 large loaf pans, 3 smaller loaf pans, or 5 mini loaf pans.
In a medium bowl mix together cake mix, instant pudding, water, and poppy seeds. Add the oil and eggs and beat with a mixer on medium speed for about 4 minutes.
Divide batter into greased baking pans. Bake for 35 minutes (regular-medium sized loaf pans), or until toothpick comes out clean. Cool on a cooling rack, and store in a covered container. See notes for other bake times.
Mini muffins take about 11-12 minutes.
Mini loafs take about 20-30 minutes.
In any type of bake just make sure the toothpick comes out clean.
