Tart rhubarb and rich coffee make a cozy pair. The fruit brings bite, and the coffee adds a roasted edge.
That is what makes this rhubarb coffee cake feel old-school and a little special. It has the comfort of a breakfast cake with more depth than the usual sweet pan bake.
What makes rhubarb coffee cake with coffee different
The difference is simple: brewed coffee goes into the batter. That keeps the crumb moist and the finish less sugary.
☕ Did You Know?
Many traditional coffee cakes contain no coffee at all. The name originally referred to a cake served alongside coffee rather than one made with it. Adding brewed coffee directly to the batter gives this rhubarb coffee cake extra depth, helps balance rhubarb’s tartness, and keeps the crumb moist without making the cake taste like a mocha dessert.
How brewed coffee boosts the flavor
Cooled coffee won’t make the cake taste like mocha. It lifts cinnamon, brown sugar, and rhubarb, so the sweetness feels balanced.

Why rhubarb needs a sweet partner
Rhubarb is tart and earthy. Sugar softens it, coffee rounds it off, and strawberries make the cake friendlier without hiding the bite.
The key ingredients that make this cake work
The base is simple: flour, eggs, sugar, baking soda, cinnamon, and salt. Then come 3 cups of chopped rhubarb and 1 cup of cold coffee. Many bakers add 1 1/2 cups of strawberries, plus brown sugar and optional pecans on top.
Choosing the right coffee for baking
Use cooled brewed coffee with a smooth, medium profile. A stronger brew adds depth, but it shouldn’t drown the fruit.

Fresh rhubarb, strawberries, and optional pecans
Cut the fruit evenly so it bakes at the same pace. Rhubarb brings the bite, strawberries add sweetness, and pecans give the top crunch.
How to bake it for the best texture
Heat the oven to 350 degrees F and grease and flour a 9×13-inch pan. Beat sugar and eggs until smooth, mix in the coffee, whisk the dry ingredients separately, then combine and fold in the fruit. One pan gives about 15 pieces.
Mix gently so the cake stays tender
Stop mixing as soon as the batter comes together. Too much stirring can make the crumb tight and heavy.
Watch for the signs it is done
Spread the batter in the pan, add brown sugar and pecans if using, and bake 45 to 50 minutes. The top should be golden, and a toothpick from the center should come out clean.
