Instructions
Pre-heat the oven to 350°F. Line a 9 x 9 inch baking pan with parchment paper that extends over the sides.
Make the Topping
Combine the brown sugar, gluten-free flour, and cinnamon in a medium size bowl. Mix well. Cut in the butter with a pastry cutter, fork, or your fingers.
Set aside.
Make The Cake Batter
Combine all the dry ingredients in a large bowl and whisk.
In a separate bowl combine all the wet ingredients and mix well then add it to the dry ingredients and mix again.
Take 2 TBSP of the topping mixture and sprinkle it over the batter and then mix it into the batter.
Add the blueberries to a small bowl and add 1 Tbsp of flour to the blueberries and mix. Then gently fold them into the batter.
Pour the batter into the prepared parchment lined pan.
Dollop the blueberry jam onto the top of the batter and swirl it in with a butter knife.
Sprinkle the top of the cake with the streusel topping.
Place the baking pan onto a baking sheet pan to catch any spills.
Bake 50-60 min or until tester comes out clean.
If topping starts to get too brown, cover it with foil and continue to bake until done.
Make the Glaze
Once the cake is cooled make the glaze.
In a small bowl combine the powdered sugar and vanilla extract.
Slowly add milk to reach the desired consistency. You want it thick but pourable so you may not need all the milk.
Drizzle over the cooled cake.
Notes
You can make this cake using regular flour and dairy, just swap them out where needed.
The cake will be very tall so make sure you have the parchment paper higher than the top of the baking pan and place the baking pan on a baking sheet to catch any spills.
Cup 4 Cup flour has dairy in it, so if you plan on making it dairy-free please choose another gf flour such as King Arthur Measure for Measure. I have not tried any brand other than the two listed.
