These easy sheet pan overnight oat cups combine creamy oats, fresh blueberries, and honey for a fuss-free, wholesome breakfast that’s perfect for busy mornings and meal prep.
Do not overmix the batter to avoid gummy texture. Use silicone muffin cups for easier removal and cleanup. Let oat cups cool fully before removing to prevent sticking. Frozen blueberries can be used without thawing to avoid watery batter. Baking time may vary by oven; check at 20 minutes if oven runs hot.
