Streusel is that heavenly, insanely delicious, crumbly topping made from flour, butter and sugar. It’s used to top cakes, pastry, muffins, pies and sometimes used as a layer in the middle of cakes. There are lots of variations, like using brown sugar or adding in spices such as cinnamon, cardamom or allspice.

There are only a two simple steps to creating a tasty streusel topping. 1. In a small bowl, mix together all of the ingredients, except the butter. 2. Use a pastry blender or fork to cut the cold cubed butter into the streusel mix. This process creates a crumbly mixture, known as streusel, instead of one mass of dough.

*Pro Tips – for the best overnight french toast

Oven French Toast is an incredible time-saver when making breakfast for a crowd.

Assemble everything the night before, then just pop the casserole in the oven. Imagine being free to just sit down, relax and enjoy your morning coffee until breakfast is done.

  • too much dairy or not enough mixing results in a thin custard mixture which can easily make your bread soggy. Measure your ingredients carefully and vigorously whisk the eggs into the cream and milk until completely combined.
  • use the right bread. Standard sliced loaf bread is not sturdy enough to absorb the custard and retain a nice texture. An Italian or French loaf are great for baked french toast, as well as Brioche or Challah.
  • day old bread is best for making french toast. Bread with too much moisture will not absorb the custard mix as readily as day old or dried bread. (see instructions below for drying bread)
  • say “yes” to fresh blueberries! Drain any juice before adding the blueberries to the bread. Thawed frozen blueberries are okay to use as long as the blueberries are well-drained, otherwise, say “hello” to purple french toast!
  • soak the bread for at least 15 – 20 minutes before baking. The entire slice should be coated and soaked in the custard. You might need to press down on the bread to help the custard absorb.
  • adjust the sugar to your tastes – use less sugar if you are going to serve the french toast with syrup or dusted with powdered sugar.
  • buy extra blueberries to use later for garnish and for a luxurious touch, warm your syrup before serving.
