How to Prepare Decadent Butterbeer Cake Jars
Ingredients
- 3/4 cup Unsalted Butter
- 1 cup Granulated Sugar
- 3 large Eggs
- 1 tsp Vanilla Extract
- 2 1/4 cups All-Purpose Flour
- 2 tsp Baking Powder
- 3.4 oz Instant Butterscotch Pudding Mix
- 1/2 tsp Salt
- 1 1/4 cups Cream Soda
- 1 box Instant Butterscotch Pudding Mix
- 2 cups Heavy Cream
- 8 oz Cream Cheese
- 1/4 cup Unsalted Butter
- 6 cups Powdered Sugar
- 1/4 cup Cream Soda
Instructions
- Preheat the Oven: Begin by preheating your oven to 350°F (175°C). This step is crucial as it ensures an even baking process. Grease your baking pan generously to prevent the cake from sticking.
- Cream Butter and Sugar: In a large mixing bowl, use a hand mixer or a stand mixer to beat the unsalted butter and granulated sugar together until the mixture is fluffy and pale. This aeration incorporates air, creating a light texture in your cake.
- Add Eggs and Vanilla: Add the eggs one at a time to the butter-sugar mixture, mixing well after each addition. This gradual method helps the eggs incorporate thoroughly, contributing to the overall stability and structure of your cake. Stir in the vanilla extract for added flavor.
- Mix Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking powder, instant butterscotch pudding mix, and salt. This step evenly distributes the leavening agent and flavorings, preventing clumps from forming which could lead to uneven texture.
- Combine Wet and Dry Ingredients: Gradually add the dry mixture to your creamed mixture, alternating with the cream soda. Start and end with the dry mixture to maintain the cake’s moisture. Mix until just combined; overmixing can lead to a dense cake.
- Bake the Cake: Pour the batter into the prepared baking pan, spreading it evenly. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Keep an eye on the cake to avoid overbaking, which can dry it out.
- Cool the Cake: Once baked, remove the cake from the oven and allow it to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely. Cooling is essential to prevent the frosting from melting when applied.
- Prepare the Frosting: To make the frosting, begin by beating the heavy cream in a large bowl until stiff peaks form. In a separate bowl, beat together the cream cheese, unsalted butter, and powdered sugar until smooth and creamy. Slowly add the cream soda, mixing until fully combined and fluffy.
- Layer the Cake in Jars: Break the cooled cake into small pieces and begin layering in clean jars. Start with a layer of cake, followed by a layer of frosting. Repeat the layers until the jars are full, creating a delightful visual effect.

How to Store Decadent Butterbeer Cake Jars
To keep your cake jars fresh and delicious:
- Refrigeration: Store any leftover cake jars in the refrigerator. They can last up to five days, thanks to the cream and cake, which both benefit from cooler temperatures.
- Sealing: Ensure the jars are tightly sealed to prevent them from drying out and absorbing other odors in the fridge.
- Freezing: For longer storage, you can freeze the cake pieces separately and the frosting. Avoid freezing the assembled jars, as the texture may change. When ready to eat, thaw in the refrigerator overnight before assembling.
Tips for Mastering Decadent Butterbeer Cake Jars
- Room Temperature Ingredients: Using room temperature butter, eggs, and cream cheese ensures they blend smoothly, resulting in a consistent batter and frosting.
- Proper Measurements: Measure your ingredients accurately. Using a kitchen scale can help ensure precision, particularly with flour and powdered sugar.
- Test for Doneness: Use a toothpick to check if your cake is done. The toothpick should come out clean or with a few moist crumbs.
- Frosting Consistency: Ensure your frosting is thick enough to hold up in layers. If it is too runny, add extra powdered sugar to thicken it up.
- Avoid Overfilling Jars: Leave some space at the top of the jars to prevent overflowing, particularly when layering.
Variations
Feel free to customize your Butterbeer Cake Jars with these ideas:
- Flavor Alternatives: Use chocolate cake instead of butterscotch for a rich, chocolatey version, or add spices like cinnamon for a warm twist.
- Seasonal Adjustments: Incorporate seasonal flavors, such as pumpkin spice in fall or peppermint in winter for holiday cheer.
- Diet-Friendly Options: Substitute gluten-free flour and sugar alternatives to make this recipe accessible for various dietary needs.
- Decorative Toppings: Top off the jars with crushed toffee bits or sprinkle of sea salt for added texture and flavor contrast.
FAQ
- Can I use homemade cake instead of box mix?
Absolutely! Feel free to use your favorite homemade butterscotch or vanilla cake recipe instead of a box mix. Just ensure the texture is light and fluffy for optimal layering. - Can I make this recipe ahead of time?
Yes! You can prepare the cake and frosting in advance. Store them separately and assemble the jars on the day you plan to serve them for best freshness. - What if I don’t have cream soda?
If you don’t have cream soda, you can use a mix of lemon-lime soda and a little vanilla extract to mimic the carbonation and sweetness. - Can I adjust the sweetness of the frosting?
Yes! If you prefer a less sweet frosting, reduce the amount of powdered sugar or incorporate some unsweetened whipped cream to balance the flavors. - Is it necessary to use instant pudding mix?
The instant pudding mix adds a rich butterscotch flavor and moisture to the cake. However, you can experiment with using a homemade custard instead, just be mindful that it may change the cake’s consistency.
