			For the Crust & Topping:
- 7 tablespoons (99g) unsalted butter, softened to room temperature
 
- 3/4 cup (150g) light or dark brown sugar, packed
 
- 1 teaspoon vanilla extract
 
- 1 cup (125g) all-purpose flour (spooned & leveled)
 
- 1 teaspoon baking powder
 
- 1/4 teaspoon salt
 
- 1 cup (85g) old-fashioned oats or quick oats (not instant)
 
For the Lemon Filling:
- 1 can (14 ounces) full-fat sweetened condensed milk
 
- 6 tablespoons (90ml) lemon juice (from about 2 lemons)
 
- 1 tablespoon lemon zest (from about 1 lemon)
 
		 
	 
	
		
		
			
- Prepare the oven and pan: Preheat the oven to 350°F (177°C). Line an 8-inch square baking pan with parchment paper for easy removal of the bars.
 
- Make the crust and topping: Using a handheld or stand mixer with the paddle attachment, beat the softened butter and brown sugar on medium-high speed until fully combined, about 1 minute. Scrape down the sides of the bowl, then add the vanilla extract. Beat again on medium-high for 30 seconds until incorporated. Add the flour, baking powder, salt, and oats. Mix on medium speed until combined. The mixture should be crumbly and dry, totaling 3 to 3.5 cups.
 
- Form the crust: Press slightly more than half of the crumble mixture into the bottom of the prepared pan to form the crust. Bake for 12 minutes, then remove from the oven.
 
- Make the lemon filling: In a medium bowl, whisk together the full-fat sweetened condensed milk, lemon juice, and lemon zest until smooth and thick.
 
- Assemble the bars: Pour the lemon filling over the warm crust and spread evenly. Sprinkle the remaining crumble mixture on top.
 
- Bake: Return the bars to the oven and bake for 22 to 25 minutes, or until the edges are lightly golden and the center is set. Avoid over-baking.
 
- Cool and cut: Remove from the oven and cool completely on a wire rack. Use the parchment paper to lift the bars out of the pan and slice into squares.
 
- Storage: Store at room temperature for up to 2 days or refrigerate for up to 1 week. Freeze cut bars in a single layer separated by parchment paper for up to 3 months. Thaw overnight in the refrigerator before serving.
 
		 
	 
	
		Notes
		
			
- Use full-fat sweetened condensed milk for the filling; fat-free versions will not set properly.
 
- You can double the recipe and bake in a 9×13-inch pan: increase crust pre-bake time to 18 minutes and bake filled bars for 35 minutes or until set.
 
- Do not over-bake the bars to maintain a soft and chewy center.
 
- Use parchment paper to easily lift bars out of the pan.
 
- Old-fashioned oats or quick oats work best; avoid instant oats.
