Ingredients for Rhubarb Buckle with Crumb Topping
You don’t need a long grocery list for this one. Here’s what I use:
Buckle:
- 2 cups chopped fresh rhubarb
- 1 teaspoon lemon juice (to brighten up the rhubarb)
- 1 ½ cups all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- 1 cup granulated sugar
- ½ cup unsalted butter, softened
- 1 large egg
- 1 teaspoon vanilla extract
- ½ cup buttermilk (or regular milk with a splash of vinegar)
Crumb Topping:
- ¾ cup all-purpose flour
- ½ cup brown sugar, packed
- ½ teaspoon ground cinnamon
- ¼ teaspoon salt
- 6 tablespoons cold unsalted butter, cut into small pieces
How I Make This Rhubarb Buckle with Crumb Topping
Here’s the step-by-step that I follow, and honestly, it’s pretty straightforward:
Preparing the Rhubarb
- Toss the chopped rhubarb with lemon juice in a bowl. This keeps it fresh and zesty.
- Set it aside while you prep the batter.
Making the Batter
- Whisk together the flour, baking powder, baking soda, and salt in a separate bowl.
- Cream the softened butter and sugar until light and fluffy. This part feels like a mini arm workout but so worth it.
- Beat in the egg and vanilla extract until smooth.
- Alternate adding the dry ingredients and buttermilk to the butter mixture, starting and ending with the dry ingredients. Mix just until combined—overmixing is the enemy here.
Crumb Topping Magic
- Combine the flour, brown sugar, cinnamon, and salt in a bowl.
- Cut the cold butter into the mixture using your fingers or a pastry cutter until it looks like coarse crumbs. This is where that crumbly magic happens.
Putting It All Together
- Pour the batter into a greased 9-inch square baking pan.
- Spread the rhubarb evenly over the batter.
- Sprinkle the crumb topping generously over everything. Don’t be shy here—this is the best part.
- Bake at 350°F for about 45 to 50 minutes or until a toothpick inserted in the center comes out mostly clean (a few crumbs are okay).
- Cool slightly before digging in.
Serving The Rhubarb Buckle with Crumb Topping
I like to serve this warm with a scoop of vanilla ice cream or a dollop of whipped cream. But honestly, it’s great cold too if you’re feeling rebellious.
- Breakfast treat: Pair with a cup of coffee and pretend it’s totally acceptable to eat cake for breakfast.
- Afternoon snack: Goes perfectly with tea or a glass of cold milk.
- Dessert: Add a drizzle of honey or a sprinkle of powdered sugar for a fancy touch.
Tips
- Don’t skip the lemon juice on the rhubarb. It keeps the tartness fresh and bright.
- Cold butter for the crumb topping is non-negotiable. Warm butter just won’t give you that crumbly texture.
- Mix gently but thoroughly. You want the batter smooth, but overmixing makes it tough.
- Use fresh rhubarb if you can. Frozen rhubarb tends to be too watery and mushy.
- Let it cool a bit before slicing. If you’re impatient like me, you’ll want to dig in immediately, but it cuts cleaner when it’s not piping hot.
Variations I’ve Tried (and Loved)
- Add strawberries with the rhubarb for a sweeter, juicier buckle.
- Swap the cinnamon in the crumb topping for nutmeg or ginger for a different spice profile.
- Use oats in the crumb topping for extra crunch and a bit of rustic charm.
- Make mini buckles in muffin tins for portion control and instant cuteness.
