My Tips for the Best Breakfast Squares
- Keep the streusel cold. Cold butter gives the topping distinct crumbs that bake up crunchy instead of melting into a flat sugary layer.​
- Avoid overmixing. Once the flour goes into the batter, I stir only until combined to keep the crumb soft and tender.​
- Watch the bake time. Ovens vary, so I start checking at 28 minutes. Pulling the pan when a toothpick comes out clean helps prevent dryness.​
- Let them rest before cutting. A short cooling time keeps the squares from crumbling and helps the flavors settle.
Variations I Love
Warm Cinnamon Streusel Breakfast Squares are easy to customize with whatever I have on hand.
- Nutty crunch: I add a handful of chopped pecans or walnuts to the streusel for extra texture.​
- Spiced version: I mix a pinch of nutmeg or cardamom into the streusel for a deeper, bakery‑style flavor.​
- Fruit swirl: Before sprinkling on the streusel, I dot the batter with spoonfuls of fruit jam (like raspberry or apricot) and lightly swirl it through for jam‑streusel breakfast squares.​
- Glazed top: Once the squares cool, I drizzle a simple icing made from powdered sugar, milk, and vanilla over the streusel for a coffee‑shop look.​
How I Store and Reheat These Squares
At room temperature, Warm Cinnamon Streusel Breakfast Squares keep well for about 2 days when stored in an airtight container. For longer storage, I refrigerate them for up to 4–5 days; I like to bring slices back to room temperature or give them a quick 10–15 seconds in the microwave before serving so the crumb softens and the cinnamon aroma blooms again.​
They also freeze nicely. I wrap individual squares in plastic and store them in a freezer bag. To enjoy later, I thaw a slice overnight in the fridge or for about an hour at room temperature, then warm it briefly in the oven or microwave until just heated through.
Warm Cinnamon Streusel Breakfast Squares FAQs
Can I double this recipe for a crowd?
Yes. I double all the ingredients and bake the batter in a 9×13‑inch pan. The baking time will be a little longer—usually around 30–35 minutes—so I start checking with a toothpick at the 30‑minute mark.​
Can I use brown sugar in the streusel?
Absolutely. Using part or all brown sugar adds a deeper, caramel note and makes the crumbs slightly softer and more flavorful. I often do half white sugar, half brown sugar in the topping.​
Can I add cinnamon to the cake batter too?
If I want extra warmth, I whisk 1/2–1 teaspoon of cinnamon into the flour mixture before adding it to the batter. This gives the whole square a gentle spice throughout, not just on top.​
What’s the best way to serve these for brunch?
I like to arrange Warm Cinnamon Streusel Breakfast Squares on a platter, dust them lightly with powdered sugar, and set them out with fresh fruit and yogurt. They’re also fantastic with a strong cup of coffee or chai latte on the side.​
