Notes
Ingredient Notes
Eggs: Bring to room temp to help everything come together smoothly.
Caramel Sauce: Use the caramel ice cream topping that comes in a squeeze bottle. I used Hershey's.
Butter: Use softened butter. Around 1 hour on the counter top should do the trick, but if you're in a hurry cut it into smaller pieces to speed up the process.
TipsKrystle's Tips and Tricks
Easy release: Line your cake pans with parchment paper to ensure your cake come out easily every single time.
Use a cake board: Build your cake with a piece of cake board on the bottom for added stability. Place a dollop of buttercream on the board to prevent your cake from sliding around. This will make it easier to carry from one place to another. It also helps you frost on a rotating cake stand if you desire.
Use a cake leveler for flat layers. This will make stacking them much easier, and also makes it less likely they'll slide off.
Chill Cake: Chill cake after your first layer of frosting. This will help the crumbs stay sealed in, not dragged through the frosting.
Don't Make These Common Mistakes
Do not overbake: Your cake is done when a toothpick inserted in the center comes out clean. It is okay if it has a few crumbs. However, it if still has wet batter continue baking in 2-3 minute increments. Overbaking leads to a dry cake.
Don't Overmix: This can cause too much gluten to develop leading to a tough, dense cake.
Uneven Layers: I like to weigh my cake pans to ensure each layer is the same size. This ensures they bake evenly and layer perfectly.
