- Wash the blueberries in a large colander then place them in a large pot of boiling water. Once the water returns to a boil, immediately turn off the heat.
- Remove the blueberries with a slotted spoon, placing them in a bowl covered with a clean kitchen towel to stay warm. Alternatively, you can run the blanched blueberries through the same colander to drain the juices, then place in a bowl and cover to keep warm.
- In a large saute or sauce pan, combine the granulated sugar, Clear Jel, water, and lemon juice, stirring constantly over medium heat until the granulated sugar and Clear Jel dissolves.
- Continue to stir until the mixture thickens and turns into the clear-like gel filling. (7-8 minutes)
- Remove from heat, then add in the blanched blueberries, stirring until fully mixed.
- Place the blueberry filling in a medium-size bowl to cool completely before using in the coffee cake. If not using right away, you can allow the filling to cool completely, then place in a tightly sealed container, and refrigerate it for up to a week.

- Using your hand-held mixer or stand mixer fitted with the paddle attachment, beat together the unsalted butter and vegetable shortening on medium-high speed until well smooth and creamy.

- Reduce the mixer speed to low and gradually add in the whisked dry ingredients until just combined. Be careful not to over mix the batter!
- Spread 2/3 of the batter into the bottom of the prepared 13” x 9” baking pan.
- Top with the homemade blueberry pie filling, then drop spoonfuls of the remaining batter over the top.
