The Method for Sheet Cake Bites

Now onto the fun part—baking! Follow these steps to create your Sheet Cake Bites:
Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). Grease your 9×13 inch baking pan to prevent sticking.
Step 2: Combine Dry Ingredients
In a large mixing bowl, whisk together the sugar, flour, salt, and cocoa powder until well combined. Set aside.
Step 3: Heat Butter and Water
In a medium saucepan, melt the butter over medium heat. Add the water and bring it to a boil. Once boiling, pour the butter and water mixture into the dry ingredients and mix until combined.
Step 4: Add Buttermilk and Eggs
Stir in the buttermilk, eggs, and baking soda into the mixture until smooth and well incorporated.
Step 5: Bake the Cake
Pour the batter into the prepared baking pan and spread it evenly. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
Step 6: Cool the Cake
Once baked, remove the cake from the oven and let it cool in the pan for about 10 minutes. Then, transfer it to a cooling rack to cool completely.
Step 7: Prepare the Frosting
In a separate bowl, beat together the ½ cup of butter, cocoa powder, powdered sugar, milk, and vanilla extract until smooth and creamy.
Step 8: Frost the Cake
Once the cake is completely cooled, spread the frosting evenly over the top.
Step 9: Cut Into Bites
Chop the cake into bite-sized squares or rectangles. Sprinkle chopped walnuts on top for an added crunch and flavor.
Seasonal Flavor Boosts

Want to elevate your Sheet Cake Bites even more? Consider these seasonal flavor boosts:
- Mint Extract: Add a few drops of mint extract for a refreshing twist.
- Orange Zest: Incorporate some orange zest into the batter for a citrusy flavor.
- Spices: A pinch of cinnamon or nutmeg can add warmth and depth.
- Fruit: Mix in some chopped strawberries or raspberries for a fruity surprise.
Steer Clear of These
When making your Sheet Cake Bites, be mindful of the following:
- Overmixing the batter can lead to dense cake bites. Mix just until combined.
- Using expired baking soda can affect the rise and texture of the cake.
- Don’t skip cooling the cake completely before frosting to prevent melting.
Save It for Later
If you find yourself with leftover Sheet Cake Bites (if that ever happens!), here are some tips to save them for later:
- Store them in an airtight container at room temperature for up to 3 days.
- For longer storage, freeze the bites in a single layer on a baking sheet, then transfer to a freezer-safe bag for up to 3 months.
- Thaw frozen bites in the refrigerator overnight before serving.
