Cinnamon Toast Crunch Layer Cake
My cinnamon toast crunch cake has moist and fluffy cinnamon cake topped with fluffy buttercream and crunchy cereal pieces. This tastes just like my favorite cereal in cake form!
If you grew eating Cinnamon Toast Crunch while watching Sunday morning cartoons this is the cinnamon cake recipe for you. It is so moist and topped with the best cinnamon sugar frosting. Can't get enough cinnamon? Try my Cinnamon Roll Pancakes, or a Cinnamon French Toast Casserole next.
Why This Recipe Works: A Sprinkle of Food Science
- Use Buttermilk. It is slightly acidic which gives a soft crumb and also interacts with the baking soda for rise.
- Use Brown Not White Sugar: It holds more moisture and helps keep our cake soft for days.
- Textural Contrast. Crunchy cereal works perfectly with the soft cake and fluffy icing.
- Use Two Leaveners: Baking soda works right away when it meets the acidic buttermilk. Baking powder helps the cake rise during its whole duration in the oven.
Ingredient Notes and Shopping Tips
- Flour: Be sure to measure it correctly by spooning into a measuring cup and leveling with a knife. Avoid dipping your cup into the flour container as you'll likely use too much leading to a dry, dense cake.
- Leaveners: Replace these once or twice a year even if they're still in date. In our text kitchen we write the date we open it on the lid and toss in 6-12 months.
- Cinnamon: For baking I like the sweet and spicy flavor of Simply Organic Ceylon cinnamon, grab it if you see it!
- Eggs: Bring to room temp to help everything come together smoothly. Short on time? Place the in a bowl of warm water for 5-10 minutes.
- Buttermilk: No buttermilk? No problem! Add 1 ½ tablespoons of vinegar or lemon juice with the 1 ½ cups of milk.
Krystle's Tips: Steal My Culinary School Secrets
- Don't Overmix: Mix until the streaks of flour just disappear. Overmixing leads to a gummy, tough cake.
- Perfectly Even Layers: I stink at eyeballing this so I divide it by weight using a food scale.
- Don't Overbake: Bake until a toothpick inserted in the center comes out with a few moist crumbs. If its totally clean you may have overbaked your cake which can make it dry.
- Frost Like a Pro: Do a thin layer of frosting (crumb cake) and then refrigerate for 30 minutes. Frost with an offset spatula for smooth bakery style icing.
- Add Cereal Last: I like to add this just before serving to keep it crunchy.
