Expert Tips

- Fresh Blueberries: Use fresh blueberries for the best flavor and texture; if using frozen, do not thaw them to prevent excess moisture.
- Butter Temperature: Ensure your butter is softened, not melted. This helps create a light, fluffy cake when mixed with sugar.
- Mixing Method: Mix the batter until just combined; overmixing can lead to a dense Lemon Blueberry Coffee Cake in a 9×13 Pan.
- Baking Time: Keep an eye on the cake towards the end of baking time; ovens can vary, and you want it perfectly baked without drying out.
- Glaze Consistency: Adjust the glaze by adding more lemon juice or powdered sugar to achieve your desired thickness; it should drizzle easily but hold its shape.
- Cooling Time: Let the cake cool for at least 10 minutes before adding the glaze; this allows the cake to set and prevents the glaze from melting away.
