Chocolate Chip Snack Cake with Chocolate Frosting Ingredients

For the Cake

Unsalted butter
This is your flavor base. It adds richness and helps create that soft, tender crumb.

Granulated sugar
Sweetens the cake and helps create a light, fluffy texture when creamed with butter.

Light brown sugar
Adds moisture and a subtle caramel flavor that makes the cake extra cozy.

Eggs
Bind everything together and give the cake structure. Room temp eggs mix in much more smoothly.

Sour cream
The secret weapon here. Sour cream makes the cake incredibly moist and gives it that soft, melt-in-your-mouth texture.

Milk
Adds just enough liquid to keep the batter smooth and balanced.

Vanilla extract
Brings warmth and enhances all the other flavors.

All-purpose flour
The base of the cake. Be careful not to overmix once it’s added.

Baking powder + baking soda
These work together to give the cake lift and a light texture.

Salt
Balances the sweetness and enhances the flavor.

Chocolate chips
The star of the show. You’ll get little pockets of melted chocolate throughout every bite.

Tips, Tricks, and Substitutions

• Use room temperature ingredients for a smoother batter and better texture
• Don’t overmix the batter once you add the flour or the cake can turn dense
• Mini chocolate chips work great if you want more even chocolate distribution
• Swap sour cream with Greek yogurt in a pinch
• Add flaky sea salt on top for a sweet-salty finish that’s so good
• Want extra chocolate? Mix some chips into the frosting or sprinkle on top

If you love that sweet and salty combo, you should try it on my brown butter chocolate chip cookies too — it’s next level.

How to Make Chocolate Chip Snack Cake

1.  Preheat the oven to 350°F and grease and line an 8x8 or 9x9 pan.
2. In a large bowl, cream the butter, granulated sugar, and brown sugar together until light and fluffy, about 2–3 minutes.
3. Add the eggs one at a time, mixing well after each addition. Stir in the sour cream, milk, and vanilla until smooth.
4. In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
5. Add the dry ingredients to the wet ingredients and mix until just combined.
6. Fold in the chocolate chips.
7. Pour the batter into the prepared pan and smooth the top.
8. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
9. Let the cake cool completely before frosting.

How to Make Chocolate Frosting

• Beat the butter until smooth and creamy.
• Add the powdered sugar and cocoa powder and mix until combined.
• Add the milk, vanilla, and salt, and beat until smooth and spreadable.
• Adjust milk as needed for your desired consistency.

Frost and Serve

Spread the chocolate frosting over the completely cooled cake.
Top with extra chocolate chips or a sprinkle of flaky sea salt if you’re feeling fancy.

Cut into squares and serve!

Why This Cake is so Moist

• Sour cream adds richness and locks in moisture

• The balance of fat and liquid creates a tender texture

Basically… it’s hard to mess this one up.

Optional Upgrades

•  Use mini chocolate chips for better distribution
• Add a sprinkle of flaky sea salt on top
• Serve warm with a scoop of vanilla ice cream (highly recommend)

FAQ

Can I make this chocolate chip snack cake ahead of time?
Yes! You can bake the cake a day in advance and frost it before serving.

Can I freeze this cake with frosting?
You can, but the texture of the frosting is best fresh. If possible, freeze the cake unfrosted.

Can I use Greek yogurt instead of sour cream?
Yes, full-fat Greek yogurt works great and gives a similar texture.

Why did my cake turn out dense?
Most likely from overmixing the batter after adding the flour. Mix just until combined.

Can I use a different pan size?
An 8x8 or 9x9 pan works best. A larger pan will make the cake thinner and bake faster.
