Chef Emma’s Helpful Tips
- Make-Ahead Option: This cake stores beautifully! You can bake it a day in advance, letting the flavors deepen overnight. Just cover it tightly to maintain freshness.
- Ingredient Swaps: If you prefer granulated sugar, you can replace erythritol with the same amount of sugar, but keep in mind this will change the nutritional profile.
- Slicing Perfectly: Ensure the cake has cooled completely before slicing; it helps maintain its fluffy texture and makes it easier to serve.
- Storage Suggestions: Store leftovers in an airtight container in the fridge for up to a week. It also freezes well for up to three months—perfect for a rainy day treat!
