Substitutions
Here are some tried and tested substitutions and variations for swapping ingredients in this recipe!
- Blackberries: Omit, use frozen, or substitute with raspberries.
- Nutmeg: Optional, can be omitted.
- Plant-based milk: Any variety can be used, such as soy, almond, or oat milk.
- Brown sugar: Replace with granulated sugar if needed. Oh and if you’re a baking nerd like myself – check out this cool guide from the Kitchn on all things sugar so you know which ones to use for your baking adventures.
Storage
Store the coffee cake in an airtight container or tightly covered for up to 3 days, but it’s best enjoyed fresh. For longer storage, freeze in an airtight container for up to 2 months. To reheat, thaw at room temperature for 3 hours if frozen, then warm in the oven if desired.
Expert Tip
Want your blackberries to stay at the top of the cake, not the bottom? Portion out about 1/4 of the batter into your cake tin, then fold the blackberries into the remaining mixture and add to the cake tin. This ensures even distribution of blackberries throughout the cake, with none sinking to the bottom.
