Ingredients
Oatmeal Crumble
- 2 cups (10 oz) all-purpose flour
- 2 cups (6 1/2 oz) old fashioned oats
- 1 cup packed, (6 1/2 oz) light brown sugar
- 1 tsp baking powder
- 2 tsp vanilla extract
- 1/2 tsp table salt
- 16 tbsp (2 sticks, 8 oz) unsalted butter, softened
Blueberry Lime Filling
- 1 12 oz can sweetened condensed milk
- 1/2 cup lime juice
- 2 tsp lime zest
- 2 egg yolks
- 12 oz (about 2 cups or 1 dry pint) blueberries, washed and blotted dry
Instructions
Oatmeal Crumble
- Preheat oven to 350F. Make a sling of parchment paper for a 9 x 13 baking dish, so that the ends hang over the long sides of the dish. Grease the dish well with butter or baking spray.
- In a large bowl, mix together flour, oats, brown sugar, baking powder, vanilla, and salt. Cut the butter into tablespoon sized pieces. Add the butter to the bowl and mix with your fingers until the butter is incorporated and the mixture looks crumbly.
- Remove 2 - 2 1-2 cups of crumble and reserve for the topping. Pour the remaining crumble into the prepared baking dish. Press evenly into the dish, using the bottom of a cup or other wide, flat item.
- Bake for 10 minutes.
Blueberry Lime Filling
- Mix together the condensed milk, lime juice and zest, and egg yolks until smooth and full combined. Let the filling sit and thicken for 5-10 minutes.
- Drop the blueberries evenly over the hot crust. Dollop the lime filling over the blueberries and spread it out with a spatula. Bake the crust and filling for 7-8 minutes.
- Now sprinkle the reserved crumble topping over everything. Then bake for 30-35 minutes, until the filling is bubbly and the topping is golden brown.
- Cool in the pan for 1 hour. Run a knife along the edges of the pan. Pull the bars out of the pan with the sides of the parchment paper and transfer them to a cutting board.
- At this point you can cut the bars, though they will be soft still, or refrigerate them for at least 4 hours to firm them up. To cut use a long knife and slice straight down, wiping off the blade as needed.
Notes
- Storing: Bars can be stored in the refrigerator for 4-5 days or in the freezer for 2-3 months.
- Substitutions: Lemon juice can be substituted for the lime juice. Also, though I prefer the texture of the old-fashioned oats, you can use quick oats if needed.
