How to Make Galaxy Cookie Dough Cake
This cake is assembled in layers, combining chewy cookie dough with a smooth cream filling and a rich ganache topping. Follow these steps to create this show-stopping dessert.
Step 1: Prepare the Cookie Layers
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. In a medium bowl, whisk together the flour, baking soda, and salt. In a separate large bowl, beat the softened butter, brown sugar, and granulated sugar until light and fluffy. Add the eggs one at a time, mixing well, then stir in the vanilla extract. Gradually add the dry ingredients and mix until combined. Fold in the chocolate chips and sprinkles.
Step 2: Bake the Cookie Layers
Divide the dough into three equal portions and press each into a thin, even layer on separate parchment-lined baking sheets. Bake for 12-15 minutes, or until golden brown. Allow the cookie layers to cool completely before assembling.
Step 3: Make the Cream Filling
In a mixing bowl, beat the softened cream cheese until smooth. Add the powdered sugar and vanilla extract, mixing until well combined. In a separate bowl, whip the heavy cream until stiff peaks form. Gently fold the whipped cream into the cream cheese mixture until smooth and fluffy.
Step 4: Assemble the Cake
Place one cookie layer on a serving plate. Spread half of the cream filling evenly over the top. Add the second cookie layer, followed by the remaining cream filling. Top with the final cookie layer and gently press down to set the layers.
Step 5: Prepare the Chocolate Ganache
In a small saucepan, heat the heavy cream until just about to boil. Remove from heat and pour over the chocolate chips. Let sit for 2-3 minutes, then stir until smooth and glossy. Allow the ganache to cool slightly before pouring over the top of the cake.
Step 6: Decorate and Serve
While the ganache is still warm, sprinkle rainbow sprinkles and crushed cookies on top for extra crunch and color. Chill the cake in the refrigerator for at least 2 hours before slicing and serving to allow the layers to set.
How Long to Chill Galaxy Cookie Dough Cake
Chilling the cake is essential for achieving the perfect texture and flavor. It allows the cream filling to set and the layers to meld together. Here’s a general guideline:
- Quick Chill – 1 hour in the refrigerator (for a softer texture)
- Optimal Chill – 2-3 hours for the best consistency
- Overnight Chill – Ideal if preparing in advance, as it enhances the flavor and structure
If you’re short on time, you can place the cake in the freezer for 30 minutes to speed up the process, but be sure not to freeze it solid.
How to Store Leftovers
If you have any leftover slices, they can be stored and enjoyed later. Here’s how to keep them fresh:
- Refrigerator – Store in an airtight container for up to 4 days. Let it sit at room temperature for a few minutes before serving.
- Freezer – Wrap individual slices in plastic wrap and place them in an airtight container. They can be frozen for up to 1 month. Thaw in the refrigerator before enjoying.
Tips for the Best Galaxy Cookie Dough Cake
To make sure your cake turns out perfect every time, keep these tips in mind:
- Use Room Temperature Ingredients – This helps create a smoother dough and filling.
- Don’t Overbake the Cookie Layers – They should be slightly soft in the center since they will firm up as they cool.
- Chill Before Slicing – This ensures clean layers when cutting the cake.
- Customize the Toppings – Add crushed candy bars, chocolate shavings, or caramel drizzle for extra decadence.
- Make It Ahead – This cake is even better the next day, making it a great option for parties and celebrations.
