Whenever anything is cooked in a slow cooker, you know it’s going to be an easy recipe, and this Raspberry Zinger cake is no exception. Of course, even simple things can benefit from a little finess. These tips are very easy, but they’ll make a big difference in your cake, so don’t skip this section.

Non-Stick Spray is Vital

Don’t be stingy with the non-stick spray. The last thing you want is your delicious cake sticking to the interior of the slow cooker vessel. Get a nice, even, and thorough coat of non-stick spray all over the interior to avoid disaster.

Completely Softened Cream Cheese

Be sure your cream cheese is absolutely, completely softened. You want a fluffy, creamy frosting, and softened cream cheese is how you get there. If your cream cheese isn’t fully softened, you’ll end up with lumpy frosting that has little chunks of plain cream cheese in it.

Room Temperature Eggs

Most people don’t realize this, but using room temperature eggs is very important in baking. Room temperature eggs are less viscous than cold eggs, which allows them to more easily combine with the other cake ingredients. Because eggs help give cake its texture and height, the better they’re incorporated, the better the cake.

Cool the Cake Completely

Cool your cake completely before frosting it. You might be extremely tempted to skip this step because you’ll only be frosting the top of the cake while it’s still in the slow cooker. Where’s the frosting going to go, right? Well… yeah, the frosting isn’t going anywhere, but if your cake is warm, it’s going to turn into a sugary slurry. It won’t be frosting anymore.

Serving Slow Cooker Raspberry Zinger Cake

Serve this cake just like you would any other. Cut out a piece, put it on a plate, and enjoy! This cake is perfect with a glass of milk or a cup of coffee. Its flavor and color make it a great addition to any holiday get-together from Easter to Christmas or even just a weeknight dessert. It’s also the perfect potluck dessert. Just set out the entire slow cooker and let people serve themselves! Wherever and whenever you serve it, everyone always loves it.

Storing Slow Cooker Raspberry Zinger Cake

This cake will keep well in the refrigerator for about three days. Simply leave it in the slow cooker linger with the lid on. For longer storage, you can freeze this cake for up to one month in an air-tight, freezer-safe container.

To freeze the cake, cut it into slices so you can get it out of the slow cooker. Then freeze the pieces individually on a cookie sheet. After completely frozen, wrap them in cling wrap and then in aluminum foil. To serve let the cake defrost in the refrigerator overnight.


Before you go, take a quick look at this FAQ. It has the answers to some common questions about this recipe. They make a great little cheat sheet for quick reference.

Why is my frosting lumpy?
Your cream cheese wasn’t fully softened. If your cream cheese isn’t thoroughly softened you can end up with lumpy frosting with chunks of cream cheese in it.

My frosting got thin when I put it on my cake.
You didn’t let the cake cool enough before frosting it. Heat will make your frosting get thin, so be sure your cake is completely cooled before frosting it.

How long is this cake good?
This cake will keep well in the refrigerator for about three days. You can freeze it for up to a month, as well.

  • 6 Tablespoons Butter – melted

  • 2 2/3 cups All Purpose Flour
  • 1 Tablespoon Baking Powder
  • 1 teaspoon Salt
  • 1 cup Milk
  • 3 Large Eggs
  • 1 Tablespoon Raspberry Jello
  • 1/2 cup of fresh Raspberries – washed and drained (Extra berries for topping)


  • 1 – 8 ounce package Cream Cheese – softened
  • 1/4 cup Milk
  • 1 Tablespoon Vanilla Extract
  • 2 – 3 cups Powdered Sugar
  • 4 – 6 ounces Shredded Coconut – sweetened
  • Fresh Raspberries to garnish


  • First, spray the Crock Pot with Cooking Spray, place the lid on the crock pot, and turn the heat to HIGH, to heat the crock pot.  
  • In the mixing bowl of a stand mixer, (or with a mixer and a bowl) blend the melted Butter, and Oil with the Sugar and Vanilla, until smooth and creamy.  In a separate bowl, add the Flour, Baking Powder, salt, and Raspberry Jello, and stir until completely mixed.  
  • Add the Eggs to the mixing bowl, and blend.  Add the Flour mixture a little at a time, alternating with the Milk, until all ingredients have been added, and mixed until smooth. 
  • Remove the mixing bowl, and fold the fresh Raspberries into the cake batter.  Pour the batter into the crock pot, and cover with the lid. 
  • Cook on high heat for 1 hour, and turn heat setting to low, and cook an additional 30 minutes to and hour, or until a toothpick inserted in the center comes out clean, and cake is no longer wobbly. 
  • When cake is finished, remove the lid and be careful not to drip any condensation from the lid on the cake.  Allow cake to cool in the crock pot, until the Crock liner can be removed.  
  • Remove the crock, and let cool to room temperature.  Place cake/crock in the refrigerator if cool cake is preferred.


  • In the mixing bowl of a stand mixer, place the Cream Cheese, and milk, and blend.  Add Vanilla, and blend.  Add Powdered Sugar about 1/3 cup at a time, and mix until smooth, thick and creamy.  If Frosting becomes to thick, add a few drops of milk to thin.
  • Frost cake with all of the frosting, and generously sprinkle Coconut on top.  To serve, cut in 2 – 3 inch slices.  Enjoy!


NOTE:  For best results, place cake in refrigerator to cool before serving.  Crock Pot temperatures do vary, so just watch the cake to make sure it’s cooking, and when you turn it down, check on it about every 20 minutes until it’s done.
