Step 1

Preheat the oven to 375°F.

Step 2

Place blueberries and chopped rhubarb in the bottom of a medium-sized baking dish (roughly 6x10). Squeeze the fresh lemon juice over the fruit.

Step 3

In a medium bowl, mix together the flour, sugar, egg, and butter. The mixture should have a sandy texture. Top the fruit evenly with this mixture.

Step 4

Bake the cobbler in the preheated oven for 30 minutes, or until hot and bubbly. The topping will be slightly golden.

Step 5

Allow to cool slightly before serving with ice cream or fresh whipped cream.
