Desserts
Betty Crocker’s rhubarb pie recipe delivers that perfect tart-sweet balance we all crave—crisp oat topping meets juicy, spiced rhubarb filling in every bite. This classic dessert captures spring’s bright flavors with a foolproof method that works whether you use a store-bought crust or make your own.
The secret lies in the oat topping, which adds just the right crunch without overpowering the filling.
The filling’s magic comes from a precise sugar-to-rhubarb ratio and a pinch of cinnamon, creating a filling that’s sweet enough to satisfy but tart enough to keep your taste buds engaged.
I’ve tested this recipe countless times, and the key to success is pre-cooking the rhubarb to soften it just enough while preserving its natural juices. This ensures a filling that’s thick and flavorful, not watery.
By the time it emerges from the oven, you’ll have a pie with a golden, crisp oat topping that contrasts beautifully with the tender, bubbling rhubarb beneath. The aroma alone—warm spices and fresh rhubarb—will have everyone gathering around the table.
Serve it warm with a scoop of vanilla ice cream for the ultimate dessert experience.
This recipe is perfect for spring and summer gatherings, where the freshness of rhubarb shines. Whether you’re baking for a family dinner or a potluck, the combination of simplicity and professional results makes it a standout. Let’s get started on creating this timeless classic.

The rhubarb is the star, so grab the brightest stalks you can find—farmers markets have the freshest, but grocery stores work too. Look for vibrant red or pink stalks with no sliminess. Betty Crocker's classic uses 4 cups chopped, so don't skimp on the chopping—smaller pieces cook faster. The sugar-to-rhubarb ratio is key: too little and it's tart, too much and it's cloying. Light brown sugar adds depth without overpowering. For the crust, Pillsbury refrigerated is foolproof if you're short on time, but homemade crusts always impress guests.
No fresh rhubarb? Frozen rhubarb works perfectly—just thaw and drain well. Running out of oats? Crushed graham crackers give a similar texture. The cinnamon in the filling should be ground fresh if possible, but store-bought works fine. For the topping, quick oats won't crisp up right—stick with old-fashioned. Short on butter? Coconut oil works in a pinch, though it has a different flavor. The lemon juice brightens everything—don't skip it, even if your rhubarb seems tart enough.
This pie reheats beautifully—just warm for 10-15 minutes at 350°F to crisp up the topping. Store leftovers covered at room temp for 2 days or refrigerate for 4 days. The oat topping stays crisp for 3 days if kept dry. For serving, I always grab Breyer's vanilla ice cream—it melts just right. Make ahead tip: Assemble the pie, refrigerate overnight, then bake—this helps the filling set perfectly.

Step-by-step instructions for betty Crocker rhubarb pie recipe
This classic rhubarb pie delivers perfect tart-sweet balance with a crisp oat topping every time.
Prepare the Rhubarb Filling
In a large mixing bowl, combine the 4 cups fresh rhubarb (chopped into 1-inch pieces) with the 1.5 cups granulated sugar and 2 tablespoons lemon juice. Stir gently to coat the rhubarb evenly—this helps balance the tartness with sweetness. Let the mixture sit for 15 minutes while you prepare the crust.
After resting, transfer the rhubarb mixture to a medium saucepan. Cook over medium heat for 8-10 minutes, stirring occasionally, until the rhubarb softens and releases its juices. The filling should thicken slightly but still maintain a chunky texture. Remove from heat and stir in the 0.5 cup all-purpose flour and 1 tablespoon ground cinnamon until fully combined. This creates a perfect thickener that prevents a runny pie filling.
Assemble the Pie Crust
Roll out the pre-made pie crust on a lightly floured surface to fit a 9-inch pie dish. Press it gently into the bottom and up the sides, creating a slight overhang for the classic look. Trim any excess dough from the edges. Chill the crust in the freezer for 10 minutes while you prepare the oat topping.
Preheat your oven to 375°F. This temperature ensures the crust bakes evenly without burning. Line the chilled crust with parchment paper and fill it with pie weights or dried beans. Bake for 8 minutes, then remove the weights and bake for another 5 minutes to create a golden, flaky base. This pre-baking step prevents a soggy bottom when you add the filling.
Layer the Filling and Topping
Pour the cooked rhubarb filling into the pre-baked crust, spreading it evenly. The filling should come up to about ½ inch from the top edge. In a separate bowl, mix the 1.5 cups old-fashioned oats, 0.75 cup packed brown sugar, 1 teaspoon ground cinnamon, and 0.25 teaspoon salt. Sprinkle this oat mixture evenly over the rhubarb filling.
Dot the top with 0.5 cup cold, cubed unsalted butter for extra richness and a golden finish. The butter will melt slightly during baking, creating a crispy, caramelized topping. This step is what makes this pie uniquely delicious—don't skip it!
Bake to Golden Perfection
Return the pie to the 375°F oven and bake for 40-45 minutes, until the filling bubbles gently and the oat topping turns a deep golden brown. The edges should be set, but the center should still have a slight jiggle—this indicates the filling is fully cooked but not overdone.
Let the pie cool completely on a wire rack for at least 2 hours before serving. This resting time allows the filling to set properly and prevents a runny pie. The flavors will deepen as it cools, making each bite even more satisfying.
Serve with Vanilla Ice Cream
Slice the pie into 6 equal servings and serve warm with 1.5 cups vanilla ice cream on the side. The contrast between the tart rhubarb filling, sweet oat topping, and creamy ice cream creates an unforgettable dessert experience.
For an extra touch, brush the top with a simple egg wash (beat the 1 whole large egg with a splash of water) before baking if you prefer a glossy finish. Enjoy this classic rhubarb pie that's perfect for spring gatherings or family dinners!
Pro Tips For Making Betty Crocker Rhubarb Pie
- Trim the Stems: Cut the rhubarb stalks just below the leaf attachment point—don’t waste time peeling. The fibrous core near the stem is tougher, so slice it out if you’re feeling picky, but I’ve skipped it for years with zero complaints.
- Simmer, Don’t Boil: The filling needs a gentle simmer (low heat, small bubbles) for 15–20 minutes to thicken properly. After burning two batches at high heat, I learned: if it’s bubbling hard, it’s too hot. Cover loosely and let it work.
- Skip the Extra Flour: The recipe’s 2 tablespoons of flour is enough for thickening—adding more makes the filling gummy. If it’s still too thin after simmering, swap 1 tablespoon of cold water for cornstarch mixed with a splash of lemon juice instead.
- Chill Before Baking: Let the filling cool to room temp (30–45 minutes) before pouring into the crust. I used to rush it, and the crust would puff up unevenly or even crack. Patience here = a cleaner, prettier pie.
Regional styles of this betty crocker rhubarb pie
Classic Midwest Tartness
The Midwest takes rhubarb pie to heart with a focus on bold, rustic flavors. Here, the filling leans slightly sweeter—try 1¾ cups sugar instead of 1½ cups—to balance the region’s love for hearty desserts.
I’ve seen local bakers add a pinch of nutmeg to the filling for warmth, creating a cozy, spiced profile perfect for spring potlucks. 🌾
New England Crisp Topping
In New England, the oat topping gets a crunchier twist by adding ½ cup chopped pecans to the oat mixture. The nuts toast beautifully during baking, adding texture and a buttery depth.
Some recipes also call for a sprinkle of coarse sugar on top before baking to create a caramelized crust. This version pairs wonderfully with Breyers vanilla bean ice cream.
Southern Buttery Twist
Southern bakers often enrich the filling with 1 tablespoon cornstarch for extra thickness and a touch of butter (2 tablespoons melted) stirred into the cooked rhubarb. The butter adds richness that complements the region’s love of sweet, creamy desserts.
For the topping, some use quick oats (½ cup) mixed with the old-fashioned oats for a softer texture. Serve with whipped cream for a true Southern touch.
Pacific Northwest Freshness
Out West, where rhubarb grows abundantly, the filling stays lighter—just 1 cup sugar to highlight the tartness. The oat topping often includes 1 teaspoon cinnamon and a pinch of cardamom for an aromatic kick.
I’ve seen local bakers use local honey (2 tablespoons) instead of sugar in the topping for a floral note. Pair with local blueberry ice cream for a berry-forward dessert.
Canadian Maple Glaze
Across the border, Canadian bakers sometimes drizzle a maple syrup glaze (¼ cup maple syrup + 1 tablespoon butter) over the baked pie for a sticky, maple-forward finish. The glaze complements the rhubarb’s tartness while adding a signature Canadian touch.
For the filling, some use 1 tablespoon apple cider vinegar instead of lemon juice to enhance the fruit’s natural brightness.
Modern Shortcut Adaptations
For busy bakers, the Midwest and Pacific Northwest both popularize pre-made crusts (like Pillsbury) and instant rhubarb pie filling (found in the baking aisle). These shortcuts save time without sacrificing flavor. I’ve even seen store-bought rhubarb filling paired with a homemade oat topping—it’s a game-changer for weeknight baking. 💡

Frequently asked questions
Can I use frozen rhubarb instead of fresh?
Frozen rhubarb works perfectly—just thaw and drain it thoroughly before measuring. The texture will be slightly softer, but the flavor remains bright. For best results, squeeze out excess moisture with a paper towel to prevent a watery filling.
Why does my filling look too runny?
Runny filling usually means the rhubarb wasn't cooked long enough or too much liquid remains. Always cook the filling until it thickens slightly (about 8-10 minutes), then stir in the flour and cinnamon to bind it. If it's still too thin, simmer uncovered for 2-3 more minutes to evaporate excess liquid.
Can I make this pie ahead of time?
Yes! Assemble the pie (unbaked) and refrigerate for up to 24 hours before baking. This actually improves the filling's texture. For a fully baked pie, store at room temperature for 2 days or refrigerate for 4 days. Reheat slices at 350°F for 10-15 minutes to restore crispness.
What's the secret to the perfect oat topping?
The crispy oat topping relies on old-fashioned oats (not quick oats) and cold butter. Mix the oats with brown sugar and cinnamon, then sprinkle evenly over the filling. Dot with cold butter cubes—they melt just enough to create caramelized pockets of flavor. Bake until golden brown for that satisfying crunch.
Can I substitute the oat topping?
For a different texture, try a lattice crust or crushed graham crackers. For a Southern-style pie, use a simple streusel of ½ cup flour + ½ cup sugar + ½ cup cold butter crumbled over the filling. Just ensure your topping is dry enough to crisp properly during baking.
