Been really into blackberries this season, meaning I had to find a way to incorporate blackberries into my favorite and most simple dessert ritual: oat crumbles.
Crumbles are a super low lift and versatile dessert and I usually have all the ingredients in my pantry already.
But of course, in true tavern style, I had to pair this delicious bramble berry with a fragrant herb for a bit of ritual and whimsy.
Thyme is by far my favorite herb to incorporate into desserts (which says a lot because I also really love pairing berries with lavender). Theres a simple festive and fragrant element to thyme that truly elevates any and all desserts I create. It's an unsuspecting herb to pair with desserts, but take my word, it adds a bit of charm that will make you fall in love with it's tiny leaves and earthy smell.

As always, feel free to enjoy this recipe year round. However, like most of my recipes, I love spotlighting season produce, meaning mid-to-late summer would be the best time to enjoy this dessert. Then, or whenever blackberries are in season and abundant within your region!
