Five ingredients, one cold-butter technique—this transforms Bob's Red Mill 1:1 flour into restaurant-quality pie crust.

The Bob's Red Mill 1:1 flour is non-negotiable here—its blend of white and whole wheat creates that perfect balance of flakiness and structure. Grab it from the baking aisle or online, but avoid substitutions like all-purpose flour alone. The butter must be cold—take it straight from the fridge and cut it into 1/2-inch cubes. Store-brand unsalted butter works fine, but European-style butter with higher fat content yields extra flakiness. Keep everything chilled until you're ready to mix. The ice water is critical for binding without overheating the butter—freeze your measuring cup if your tap water isn't icy enough.

No ice water? Cold water from the fridge works in a pinch, but the texture won't be quite as tender. Short on butter? Lard or shortening can replace half, but the flavor will differ. The sugar might seem minor, but it prevents gluten development in the flour, keeping your crust light. If you're using this for a savory pie, reduce the sugar to 1 tbsp. The salt is standard, but Diamond Crystal measures differently than Morton—use the flat of a knife to level it off for accuracy. For extra flakiness, some bakers add 1 tbsp cornstarch to the flour, but it's optional.

This dough is delicate—handle it like you would a soufflé. Keep it cold until the last moment, and work quickly. Once mixed, wrap tightly in plastic and chill for at least 1 hour before rolling. The dough keeps for 3 days in the fridge or 6 months frozen, wrapped in parchment and foil. For best results, bring frozen dough to room temperature before rolling. Leftovers? Shape into a disk, freeze, and use within 3 months—it's perfect for last-minute pies.

Step-by-step instructions for bob's Red Mill one to one flour pie crust

This cold-butter method guarantees flaky layers every time—no special skills required.

In a large bowl, combine the 2.5 cups Bob's Red Mill 1:1 Flour, 2 tbsp Granulated Sugar, and 0.5 tsp Diamond Crystal Kosher Salt. Use your fingers to mix until the sugar and salt are evenly distributed throughout the flour. This step ensures balanced sweetness and seasoning in every layer of your crust.

I like to press the flour mixture gently through a fine-mesh sieve into the bowl to break up any lumps. This creates a lighter texture in the final crust. Keep the bowl set aside—we'll work with the cold butter next.

Take the 1 cup Unsalted Butter (cubed) from the refrigerator and add it to the flour mixture. Using a pastry cutter or two forks, cut the butter into the flour until you achieve pea-sized crumbles. This process should take about 5-7 minutes of consistent cutting.

Here's the key: the butter should remain cold and firm throughout. If it starts to soften too quickly, place the bowl in the refrigerator for 5 minutes to chill. You're aiming for a texture where the butter pieces are evenly distributed but still clearly visible—this creates those signature flaky layers when baked.

Sprinkle the 0.5 cup Ice Water over the flour-butter mixture, 1 tablespoon at a time. After each addition, gently toss the mixture with a fork or your fingers until the water is absorbed. Be careful not to overwork the dough—just until it begins to come together.

You'll know you've added enough water when the dough forms a shaggy mass that holds together when pressed. It should be moist but not sticky. If it feels too dry, add another teaspoon of ice water. The dough should be cool to the touch—this is crucial for maintaining those flaky layers during baking.

Turn the dough out onto a lightly floured surface and gently shape it into a disk about 1-inch thick. Wrap it tightly in plastic wrap and refrigerate for at least 1 hour (or up to 48 hours). This resting period allows the gluten to relax and the butter to firm up, which is essential for achieving that perfect flakiness.

I always press the dough into a uniform disk shape before chilling. This makes rolling it out later much easier and helps prevent uneven thickness when baking. The longer you chill the dough, the better the results—this is where the magic happens for that restaurant-quality texture.

Remove the chilled dough from the refrigerator and place it between two sheets of parchment paper. Using a rolling pin, roll the dough into a 12-inch circle, about 1/8-inch thick. Gently lift the parchment and transfer the dough to a baking sheet.

Prick the dough all over with a fork to prevent puffing during baking. Line the crust with pie weights or dried beans, then bake at 375°F for 15 minutes. Remove the weights and bake for an additional 10-12 minutes until the edges are golden brown and the bottom is lightly browned. The crust should be firm to the touch.

Pro cooking tips for bob's red mill one to one flour pie crust

Cold Butter Technique

The secret to flaky layers is keeping everything cold. Cut the 1 cup unsalted butter into ½-inch cubes straight from the fridge—never let it sit at room temperature. Use a pastry cutter or two forks to work the butter into the flour until you get pea-sized crumbles.

If the butter starts to melt, pop the bowl in the freezer for 5 minutes to reset it. This cold-butter method prevents the crust from shrinking during baking. 🧈

Ice Water Binding

Never use warm water—ice water is non-negotiable for a tender crust. Add it 1 tablespoon at a time while gently tossing with a fork. The dough should come together just enough to hold when pressed, but not stick to your fingers.

If it feels dry, add another teaspoon. The goal is a cool, shaggy mass that's ready for chilling. I keep a small bowl of ice water in the freezer for quick access.

Chilling for Success

After shaping the dough into a disk, wrap it tightly in plastic and refrigerate for at least 1 hour—I often do 2-3 hours for maximum flakiness. This resting period relaxes the gluten and firms up the butter, which is crucial for those signature layers.

Pro tip: Place the dough on a baking sheet before chilling so you can easily transfer it later without unrolling. Never skip this step—rushing leads to tough crusts. ⏰

Rolling Without Tears

Use two sheets of parchment paper to roll the chilled dough between them. This prevents sticking and makes handling easier. Roll from the center outward to maintain an even 1/8-inch thickness.

If the dough resists, let it rest for 10 minutes in the fridge. A 12-inch pizza roller works perfectly for this. Avoid pressing too hard—just enough to create a smooth surface. 💫

Preventing Shrinkage

Before baking, prick the crust all over with a fork to prevent puffing. Line the crust with pie weights or dried beans, then bake at 375°F for 15 minutes to set the shape.

Remove the weights and bake another 10-12 minutes until golden. The key is patience—rushing causes uneven browning. For extra insurance, blind-bake the crust for 20 minutes if your filling is wet (like berries).

Equipment Upgrades

Invest in a high-quality rolling pin—I recommend the OXO Good Grips for its even pressure. A pastry brush with a fine tip helps apply egg wash evenly. For shaping, a 12-inch pie dish with removable bottom is a game-changer.

If you're serious about pie-making, a pie crust shield prevents over-browning while keeping the bottom crisp. These tools make all the difference in professional results. 🔥
