Lavender Lemon Weekend Cake with Blackberry Glaze

This fragrant loaf cake combines the floral notes of lavender with bright lemon zest and a hint of blackberry sweetness. The tender crumb comes from crème fraîche, while French butter adds richness. Perfect for weekend brunches or afternoon tea, this cake showcases the classic pairing of lavender and citrus.

Tips

Tip 1

Let the sugar mixture rest after processing to allow the lavender and lemon oils to fully infuse the sugar for maximum flavor.

Tip 2

Use French butter if available as it has a higher fat content and richer flavor that complements the delicate lavender.

Tip 3

Allow the cake to cool completely before glazing to prevent the glaze from melting and running off.

FAQ

Can I use dried lavender from my garden?

Yes, but make sure it's culinary grade lavender that hasn't been treated with pesticides. Use the same amount as called for in the recipe.

What if I can't find blackberry jelly?

You can substitute with grape jelly, apricot jam, or even honey. Strain chunky jams before using to maintain smooth glaze consistency.

How long does this cake keep?

The cake stays fresh for 3 days at room temperature when covered, or up to 1 week refrigerated. The flavors actually improve after the first day.
