Tips For the Best Blueberry Crumble Cake
Light and tasty full of fresh blueberries.
- Blueberries: Use fresh or frozen blueberries for this cake with equal success. If you use fresh, be sure to rinse thoroughly and let air dry a bit before adding the flour. For frozen berries let them thaw slightly and drain any excess water from the thawing. If needed you can a teaspoon or so extra flour to help with the moisture.
- Do Not Overmix: The important part about this cake is to not overmix, this will create a dense tough cake. Especially when you are ready add the blueberries. If you over stir the batter will turn purplish-blue and your berries will begin to collapse.
- Buttermilk: This brings the all-important moisture and tang we all love in the cake. But even more important than that, it will combine with the baking soda and create a chemical reaction that will create air holes. Creating a light airy melt in your mouth texture to the cake. If you do not have any buttermilk on hand, never fear you can make it in a matter of minutes with some milk. Get the recipe here.
- Lemon: Adding lemon juice and zest adds a nice freshness to the cake. Zest your lemon after thoroughly washing and drying the outside. If you do not have a zester, use the smallest holes of a cheese grater. Stop testing when you get to the white part of the peel or pith. This is usually bitter and not very favorable. Juice the same lemon you zested for the icing.
- Nuts: If you want more of a crunch in your topping add ¼ cup of chopped pecans or walnuts to the crumble.
