🤔 FAQs
These are the questions we are most frequently asked about making rich Double Chocolate Banana Cake with Espresso Chocolate Frosting.
Start by mashing the banana in a separate bowl, adding in melted butter, sugar, eggs, yogurt, and vanilla extract. Next, add in the flour mixture and whisk until just combined. Transfer the batter to a cake tin and bake for 40-50 minutes.
The great thing about banana cake is that even with ingredients such as flour, butter, and sugar, you still get the benefits of natural sweetness and nutrients thanks to the use of bananas. Banana cake is certainly the healthier option compared to other cakes.
Banana loaf doesn’t usually have icing or frosting added to it while the cake does. While banana loaf can call for heavier flour types such as whole wheat flour and all-purpose flour, banana cake sometimes calls for lighter flours such as pastry flour or cake flour.
The cake batter is first made by combining ingredients such as a flour mixture with eggs, butter, sugar, and vanilla extract. Additional ingredients such as sour cream or heavy cream can also be added to make the cake super moist. Once baked, the cake is then topped with a chocolate icing, frosting, or ganache.
To make a moist cake, add in ingredients such as sour cream. You should also avoid overbaking the cake or overmixing the batter. Once baked, try to frost or ice the cake as soon as it has cooled sufficiently. Lastly, always store the cake properly to prevent it from drying out.
👩🏻🍳 Tips
- Avoid over stirring the cake batter as this will result in an overly dense and crumbly cake. Only stir in the flour mixture until just combined.
- To get a super smooth chocolate ganache, use an immersion blender instead of a spatula or whisk once the chocolate and boiled cream have sat for a bit.
- It’s not recommended to apply the chocolate ganache when the cake is still hot from the oven but you can do so when the cake is still slightly warm. Some of the ganache will end up soaking in the cake, making the cake even more moist and flavorful.
- Reduce the chance of bubbles in the cake batter by tapping the cake pan gently on the countertop just before adding to the oven.
- If you aren’t sure whether the cake is cooked completely, insert a toothpick into the center of the cake. It should come out clean for the cake to be properly cooked.
📚 Variations
- Instead of chocolate ganache, consider using a chocolate frosting, buttercream, or even a simple chocolate sugar glaze.
- Adjust the amount of heavy cream in the ganache to achieve a thinner or thicker consistency.
- For gluten-free chocolate banana cake, use gluten-free flour such as Bob’s Red Mill which is a like-for-like substitution.
- Plain full-fat yogurt can be used instead of sour cream.
- Chopped nuts can be added to the cake batter in addition to the chocolate chips.
🥫 Storage
Store this double chocolate banana loaf in an airtight container in the refrigerator for up to 5 days. You can also wrap the cake with plastic wrap to lock in moisture.
This cake can also be stored in the freezer for up to 3 months, with or without the chocolate ganache.
