This cranberry coffee cake puts tart berries into a simple butter cake and finishes it with a generous layer of crumbly brown-sugar streusel. Cut a square while it is still slightly warm and you can see the cranberries in the cake, not just on top.
An 8-inch square pan makes nine easy servings for Christmas breakfast, holiday brunch, or a weekend coffee break. The batter is intentionally thick, which helps hold the berries in place. You can use fresh cranberries or frozen ones straight from the freezer.
Why this cranberry coffee cake works
- The streusel uses cold butter so it stays in distinct, buttery crumbs across the top.
- Some berries are folded into the batter and the rest are scattered over it, so each square gets cranberry flavor.
- Every step uses familiar bowls and an 8-inch square pan. A mixer is not needed.
Ingredients and equipment
For the cake
- 2 cups all-purpose flour: Spoon it into the measuring cup and level it. Packed flour can make the cake heavy.
- 1/2 cup granulated sugar, 2 teaspoons baking powder, and 1/2 teaspoon fine salt: These sweeten, lift, and balance the tart berries.
- 5 tablespoons cold unsalted butter: Cut small cubes into the flour mixture until it looks like coarse meal.
- 1 large egg and 3/4 cup milk: Whisk together before adding them to the dry mixture.
- 2 cups cranberries: Halve fresh berries. If using frozen berries, leave them unthawed and whole.
For the streusel
- 1/2 cup all-purpose flour and 1/3 cup packed brown sugar form the crumb base.
- 4 tablespoons cold unsalted butter create small and large crumbs when cut into the flour and sugar.
You will need an 8-inch square baking pan, parchment, two mixing bowls, a whisk, a spatula, and a fork or pastry blender. Keep the butter cold until you are ready to use it.
How to make cranberry coffee cake with streusel
1. Prepare the pan and crumb topping
Heat the oven to 350°F. Grease an 8-inch square pan and line it with parchment, leaving an overhang on two sides. Mix the streusel flour and brown sugar, then cut in 4 tablespoons cold butter until you have irregular crumbs. Chill the bowl while you make the batter.
2. Mix a thick cake batter
Whisk the cake flour, granulated sugar, baking powder, and salt. Cut in the remaining 5 tablespoons cold butter until the mixture resembles coarse meal. Whisk the egg and milk in a second bowl, pour them into the flour mixture, and fold just until the dry flour disappears. The batter will be thick and spreadable. Stop before it becomes smooth from overmixing.
3. Add the berries and streusel
Fold 1 1/2 cups cranberries into the batter. Spread it evenly in the pan, then scatter the remaining 1/2 cup berries over the surface. Sprinkle all the chilled streusel on top in loose clumps. Do not press the crumbs into the batter.
The batter contains raw flour and egg. The FDA advises against tasting raw cake batter and recommends washing hands and utensils after handling it.
4. Bake, cool, and slice
Bake for 45 to 55 minutes. Start checking at 45 minutes in a cake-only spot near the center. A toothpick should come out clean or with a few moist crumbs, not wet batter. Check another spot if you hit a cranberry. If the streusel browns before the center is done, tent the pan loosely with foil. Cool on a rack for 20 minutes, then lift out with the parchment and cut into nine squares.
Fresh and frozen cranberry tips
Fresh berries are easy to halve, which gives smaller cranberry pockets across the cake. Frozen berries can go in unthawed. Fold them in briefly so their juice does not tint all the batter, and expect that the bake may take a few minutes longer. Use the toothpick cue rather than relying on the clock alone.
Keep the berry amount at 2 cups for the first bake. A thicker layer can leave wet pockets near the center, while substantially less fruit changes the tart-sweet balance that makes this a cranberry coffee cake.
Tips for tender cake and distinct streusel
- Measure flour lightly. Spoon it into the cup and level it rather than scooping a packed cup.
- Keep the butter cold. Warm butter can make the streusel pasty instead of crumbly.
- Stop mixing early. Fold until the last dry streak disappears. A perfectly smooth batter is not the goal.
- Check between berries. A toothpick through a juicy cranberry can look wet even when the surrounding cake is baked.
Serving, storage, and make-ahead
Serve squares slightly warm or at room temperature. For a busy holiday morning, bake the cake the day before, cool it fully, and cover it. The streusel is most distinct on the day it is baked, but the cake also makes a practical make-ahead brunch option.
For best texture, keep the plain cake covered at cool room temperature for up to 2 days or refrigerate it for up to 4 days. Refrigeration can soften the crumb topping. Wrap individual, fully cooled squares well and freeze for up to 2 months for best quality. Thaw wrapped in the refrigerator. USDA freezer guidance recommends 0°F or lower and explains that freezer storage times are quality guidelines.
Troubleshooting
Why is the center dense or wet?
The batter may have been mixed too long, the flour may have been packed into the cup, or the center may need more oven time. Measure flour lightly and check two cake-only spots near the middle. Continue baking in 5-minute increments if wet batter remains.
Why did the streusel melt into the cake?
The butter may have warmed while the batter was made, or the crumbs may have been pressed down. Keep the topping chilled and scatter it loosely just before baking.
Why are the cranberries clustered?
Fold most of the berries through the thick batter with a few gentle turns, then spread the batter evenly. Scatter the last half cup over the surface instead of piling it in one spot.
Frequently asked questions
Can I use frozen cranberries?
Yes. Add them while still frozen and fold briefly. They may release more color and the cake may need a few extra minutes in the oven.
Does cranberry coffee cake contain coffee?
No. Coffee cake is a cake to enjoy with coffee or tea; this recipe does not include coffee in the batter or streusel.
Can I make it the night before?
Bake the whole cake the day before, cool it completely, and cover it. Mixing the raw batter ahead and letting it sit overnight is less reliable because the baking powder begins working when the wet and dry ingredients meet.

Cranberry Coffee Cake with Streusel
Ingredients
Method
- Heat the oven to 350°F. Grease an 8-inch square baking pan and line it with parchment, leaving an overhang on two sides for lifting out the cake.
- In a small bowl, stir together 1/2 cup flour and the brown sugar. Cut in 4 tablespoons cold butter with a fork or your fingertips until coarse, irregular crumbs form, from pea-size to small clumps. Refrigerate the crumbs while you make the cake batter.
- In a large bowl, whisk 2 cups flour, the granulated sugar, baking powder, and salt. Cut in 5 tablespoons cold butter until the mixture looks like coarse meal. In a separate bowl, whisk the egg and milk. Pour the wet mixture into the flour mixture and fold just until no dry flour remains. The batter should be thick and spreadable; do not beat it smooth.
- Gently fold 1 1/2 cups cranberries into the batter. Spread the batter evenly in the prepared pan. Scatter the remaining 1/2 cup cranberries over the top, then sprinkle on all of the chilled streusel in loose clumps. Keep the topping on the surface rather than pressing it into the batter.
- Bake for 45 to 55 minutes, beginning checks at 45 minutes. A toothpick inserted into a cake-only spot near the center should come out clean or with a few moist crumbs, not wet batter. Check a second spot if the first hits a cranberry. If the top browns before the middle is done, tent it loosely with foil.
- Cool in the pan on a rack for 20 minutes. Lift out using the parchment, or cut directly in the pan. Slice into 9 squares. The cake can be served slightly warm or at room temperature.
