Instagram Cake is the cake I make when I want something that tastes as good as it looks on your feed. It is a one-bowl chocolate cake with a shiny ganache top and fresh berries, so you get a bakery-style finish without a bakery schedule.

I started making this for my niece's birthday because she wanted a cake that would look good in photos. The first version was dry and crumbly, so I added sour cream and hot coffee to the batter. Now it bakes up moist every single time.
You do not need a stand mixer or a piping bag here. A whisk, two bowls, and a little patience while the ganache sets are all it takes. Let us bake something worth sharing.

About the Ingredients
1 3/4 cups (220g) all-purpose flour
Spoon the flour into the cup and level it off, or your cake turns out dense. For a gluten-free version, swap in a 1:1 baking blend plus 1/4 teaspoon xanthan gum.
3/4 cup (75g) unsweetened cocoa powder
Use Dutch-process cocoa for a darker color and milder taste. Natural cocoa works too but will look more reddish-brown.
1 1/2 teaspoons baking soda
Check the date on your box because old baking soda will not lift the cake. You can substitute 1 1/2 teaspoons baking powder plus 1/2 teaspoon salt in a pinch.
1/2 teaspoon fine sea salt
Fine sea salt dissolves evenly; kosher salt works if you crush it between your fingers first. Do not skip it, since salt makes chocolate taste more chocolatey.
1 cup (200g) granulated sugar
White sugar keeps the crumb light. Coconut sugar gives a caramel note but makes the cake darker and slightly denser.
2 large eggs, room temperature
Room-temperature eggs emulsify better, so set them out 30 minutes ahead. If you forget, rest them in warm tap water for 5 minutes.
3/4 cup (180g) sour cream
Full-fat sour cream adds moisture and tang. Plain whole-milk Greek yogurt is a perfect one-for-one substitute.
1/2 cup (120ml) neutral oil, such as canola
Oil keeps the cake soft even when chilled. Melted coconut oil works but adds a faint coconut flavor.
1/2 cup (120ml) hot brewed coffee
Hot coffee blooms the cocoa and deepens the flavor; you will not taste coffee in the finished cake. Hot water plus 1 teaspoon espresso powder is a great swap.
1 cup (170g) dark chocolate chips, 60% cacao
Chop a good bar instead of using chips if you can, since it melts smoother. Semisweet chips are fine for a sweeter ganache.
2/3 cup (160ml) heavy cream
Heavy cream gives the glossiest ganache. Full-fat coconut milk from a can works for a dairy-free version.
1 cup (140g) fresh raspberries, for topping
Pat them dry so they do not bleed onto the glaze. Sliced strawberries or pomegranate seeds are lovely alternatives.
Tips & Tricks
- Do not overmix once the flour goes in. Stir just until you see no dry streaks, about 15 strokes, or the cake turns rubbery.
- Let the cake cool completely before glazing. A warm cake melts the ganache into a puddle instead of a shiny layer.
- Chill the frosted cake for 20 minutes before slicing. Cold ganache cuts cleanly and gives you those sharp photo edges.
- Measure cocoa and flour by weight if you own a scale. Cup scoops can add up to 20 percent extra flour and dry out the cake.
Pro Tips
Step-by-Step Instructions
1. Heat Oven and Prep Pan
Heat your oven to 350F (175C). Grease a 9-inch round cake pan, line the bottom with parchment, and grease the parchment too.
2. Whisk Dry Ingredients
In a large bowl, whisk the flour, cocoa, baking soda, salt, and sugar until no cocoa clumps remain.
3. Add Wet Ingredients
Make a well in the center and add the eggs, sour cream, and oil. Whisk until the batter is smooth and glossy, about 1 minute.
4. Stir in Hot Coffee
Pour in the hot coffee and whisk gently until just combined. The batter will be thin, and that is exactly right.
5. Bake the Cake
Pour the batter into the pan and bake at 350F (175C) for 30 to 35 minutes. The cake is done when the center springs back and a toothpick comes out with a few moist crumbs, or the middle reads 200F (93C) on a thermometer.
6. Cool Completely
Let the cake rest in the pan for 10 minutes, then lift it onto a wire rack. Cool fully for at least 45 minutes before glazing.
7. Make the Ganache
Heat the cream in a small saucepan over medium heat until it just bubbles at the edges, about 2 minutes, then pour it over the chocolate. Wait 2 minutes and stir until silky.
8. Glaze and Top
Set the cake on a rack over a sheet pan and pour the ganache over the center, letting it drip down the sides. Chill 20 minutes, then pile raspberries in the middle and slice.
Delicious Variations
Mocha Instagram Cake
Add 1 teaspoon espresso powder to the ganache and finish with chocolate curls instead of berries.
Peanut Butter Swirl
Warm 1/3 cup peanut butter and swirl it through the ganache with a skewer before chilling.
Berry Pink Version
Fold 2 tablespoons freeze-dried strawberry powder into the ganache for a soft pink glaze that pops in photos.
How to Store Instagram
Refrigerator
Store in an airtight container in the fridge for up to 4 days. Let slices sit at room temperature for 15 minutes before eating so the crumb softens.
Freezer
Wrap unfrosted cake layers tightly in plastic and foil, then freeze for up to 2 months. Thaw overnight in the fridge and glaze fresh.
Reheating
This cake is best at room temperature, so no reheating needed. If you want a warm slice, microwave it for 10 seconds and the ganache turns fudgy.
Frequently Asked Questions
Q: Can I make Instagram Cake without coffee?
Yes, swap the hot coffee for hot water or hot milk and the cake still bakes perfectly. The coffee only deepens the chocolate flavor, and you never taste it in the finished cake.
Q: Why did my chocolate cake turn out dry?
Dry cake almost always means too much flour or too long in the oven. Weigh your flour if you can and pull the cake when the center reads 200F (93C).
Q: How do I get a shiny ganache glaze?
Use a 1:1 ratio of chopped chocolate to hot cream and stir slowly from the center out. Do not whip it, because air bubbles dull the shine.
Q: Can I use a different pan size?
Yes, two 8-inch pans bake in 22 to 26 minutes, and a 9×13 pan bakes in 28 to 32 minutes at 350F (175C). Start checking early and trust the toothpick test.
Q: Is this cake safe for a gluten-free guest?
It can be if you use a 1:1 gluten-free baking blend plus 1/4 teaspoon xanthan gum. Check every label on your cocoa and chocolate, then bake as written.
Bake this Instagram Cake this weekend and tag me in your photos, because I love seeing your glaze drips and berry piles. Grab your whisk, preheat that oven, and let the cake cool while you make the ganache. Small steps, big impact.
