Things to know about blueberries in baking!

How do you prevent fresh blueberries from sinking to the bottom of the cake?

This is one of the most asked questions when baking with blueberries. To prevent the berries from sinking, toss the blueberries with some of the measured flour before folding them into the batter.

What is better frozen or fresh blueberries in baking?

Fresh blueberries will give you a better texture and fresh flavour in coffee cakes and muffins because they will not be fully cooked. On the other hand, frozen blueberries are good for pies, tarts and jams. But you can use either with some tweaks.

How do you prevent frozen blueberries from sinking to the bottom?

Frozen blueberries act differently in cakes. To avoid the soggy bottoms in cakes or muffins, spoon a third of the batter into the cake or muffin pan first. Then fold in floured blueberries in the remaining batter and spoon on top of the batter that is without the blueberries.

Should you thaw frozen blueberries before baking?

For baking, you don’t need to thaw frozen blueberries. However, it is best to thaw the blueberries first when preparing anything with a short cooking time, like pancakes.

  • In a medium bowl, whisk together eggs, buttermilk, honey, lemon zest, vanilla and remaining brown butter. Add wet ingredients to dry and stir until just combined. Fold in 1 cup of the blueberries
  • Transfer the batter to the prepared cake pan. Scatter and press the remaining 2 cups of blueberries on top. Scatter the walnut crumb mixture over top, breaking up any large lumps. Bake until browned on top, and a toothpick comes out clean when inserted in the middle. 60 - 65 minutes. Let cool for 30 minutes
  • To remove the cake from the pan, run a knife along the edges. Place a large plate on top of the cake pan and turn it upside down. Remove the parchment paper and place your serving plate on top and flip the cake
  • Optional; Once the cake is fully cooled, you can sprinkle it with powdered sugar or drizzle it with cream cheese icing. *Recipe on the blog
