Method
Make the batter
- In a large bowl, cream the butter and sugar together until fluffy.
- Beat in the eggs, then mix in the milk.
- Fold in the flour, baking powder, and crushed dried culinary lavender until just combined.
- Gently fold in the fresh blueberries.
Cook in the slow cooker
- Line a greased slow cooker insert with parchment and pour in the batter.
- Sprinkle the streusel topping evenly over the batter.
- Cover and cook on low for 2.5-3 hours until a toothpick comes out clean, with the tops turning just crisp.
Notes
Crush the dried culinary lavender buds finely so the flavor is fragrant, not overpowering. Refrigerate leftover lavender blueberry tea cakes in an airtight container for up to 3 days; rewarm briefly for best texture. Freezing is yes—freeze cooled cakes in a sealed container up to 2 months and thaw overnight. For a dairy-light option, replace the butter with a plant-based butter stick and use unsweetened plant milk in the same amount.
