Tips
Use Granny Smith apples for best results as they hold their shape during baking and provide tartness to balance the sweet cake.
Make sure butter is at room temperature before creaming to achieve proper light and fluffy texture.
Cool the cake completely before adding glaze to prevent it from melting and running off.
Good to Know
Cover and store at room temperature for up to 3 days or refrigerate for up to 1 week.
Can be made 1 day ahead without glaze. Add glaze just before serving.
Serve at room temperature or slightly warm. Cut into squares for serving.
Common Mistakes
Don't skip tossing apples with lemon juice to avoid browning and off flavors.

FAQ
Can I use quick oats instead of old-fashioned oats?
Old-fashioned oats work best as they provide better texture when ground. Quick oats may make the cake too dense.
What if I don't have a food processor for the oats?
You can use a blender or skip grinding the oats entirely for a more rustic texture with oat pieces throughout.
How long will this breakfast bake keep?
Store covered at room temperature for 3 days or refrigerated for up to 1 week. The glaze may soften over time.
