👩‍🍳 Step-by-Step: How to Make Strawberry Oatmeal Crumble Bars

1. Make the Crumble

• In a bowl, combine flour, oats, sugars, cinnamon, salt, and baking powder.
• Add cold, cubed butter.
• Use your fingertips or a pastry cutter to mix until you get a coarse, crumbly texture.
• Refrigerate until ready to use.

2. Prepare the Strawberry Filling

• Combine sliced strawberries with sugars, jam, lemon juice/zest, and cornstarch in a saucepan.
• Bring to a gentle boil, then simmer until thickened (about 8–10 minutes).
• Let it cool before layering.

3. Assemble and Bake

• Preheat oven to 350°F (175°C).
• Line your pan with parchment paper.
• Press about ¾ of the crumble into the bottom of the pan and pre-bake for 15 minutes.
• Spread the strawberry filling over the crust.
• Sprinkle the reserved crumble on top.
• Bake for another 25–30 minutes until golden and bubbling.
• Cool completely before slicing into bars.

• Measure flour accurately – too much flour can make the bars dry. Learn how to measure flour properly.

🧊 Storage & Freezing Instructions

These bars keep beautifully:

• Store in an airtight container in the fridge for up to 4 days.
• Freeze individually wrapped bars for up to 3 months.

🔄 Variations to Try

Feeling creative? Switch it up:

❓ FAQs

Can I use frozen strawberries?

Yes! Just thaw slightly before slicing. No need to rinse like you would with fresh berries.

How can I make these bars vegan?

Use dairy-free butter and ensure your jam doesn’t contain gelatin.

How do I prevent soggy bottoms?

Make sure the crust is partially baked before adding the filling and use parchment to help moisture escape.

Why are my bars too crumbly?

You may have added too much flour or not packed the base tightly enough before baking.

Can I use quick oats?

Quick oats can work but the texture won’t be as hearty as rolled oats.
