If you are using a 3-quart crockpot, it is recommended that a 2 lb. coffee can be used. It is suggested for a larger crockpot, 5-quart, a 9-cup Bundt pan or a 3 lb. coffee can. Mix pound cake according to package instructions.. Pour half of batter into well-greased and flour coffee, whichever size you are using. Combine streusel ingredients and sprinkle half over the cake batter. Add remaining batter and top with the rest of the streusel. Place can or pan in crockpot. Cover top of can with 8 paper towels. Cover and bake on HIGH for 3 to 4 hours. If using the Bundt pan , bake for 2 to 3 hours. From Rival Crockpot manual. ----
