This recipe quickly transforms refrigerated buttermilk biscuits into a rustic blueberry coffee cake. Featuring a sweet, buttery oat and cinnamon crumb topping, it's a simple yet satisfying dessert or breakfast treat that comes together in about 30 minutes, perfect for a homemade feel with minimal effort.
This recipe offers a convenient shortcut with refrigerated biscuits. To enhance the crumb topping, consider adding a pinch of nutmeg or a tiny bit of orange zest to the brown sugar-cinnamon mixture. When cutting the biscuits, try to keep them relatively uniform for even baking. Don't overmix the oat topping to maintain its crumbly texture. For extra moisture and richness, a light drizzle of cream cheese glaze (powdered sugar, milk, cream cheese) could be added after baking and cooling slightly. Ensure the blueberries are evenly distributed to prevent soggy spots.
