1. Place cereal mix in bowl of standing mixer and pour boiling water over it; let stand, stirring occasionally, until mixture cools to 100°F and resembles thick porridge, about 1 hour. Whisk flours in medium bowl.

2. Once grain mixture has cooled, add honey, melted butter, and yeast and stir to combine. Attach bowl to standing mixer fitted with dough hook. With mixer running on low speed, add flours, 1/2 cup at a time, and knead until dough forms ball, 1 1/2 to 2 minutes; cover bowl with plastic and let dough rest 20 minutes. Add salt and knead on medium-low speed until dough clears sides of bowl, 3 to 4 minutes (if it does not clear sides, add 2 to 3 tablespoons additional

all-purpose flour and continue mixing); continue to knead dough for 5 more minutes. Add seeds and knead for another 15 seconds. Transfer dough to floured work surface and knead by hand until seeds are dispersed evenly and dough forms smooth, taut ball. Place dough into greased container with 4-quart capacity; cover with plastic wrap and allow to rise until doubled, 45 to 60 minutes.

3. Adjust oven rack to middle position; heat oven to 375°F. Spray two 9 x 9-inch baking pans with nonstick cooking spray. Transfer dough to lightly floured work surface and cut in half crosswise with knife or bench scraper. Cut each half into thirds, then into thirds again, to make 18 even sized pieces of dough. Gently roll each piece in circular motion to make round, then roll one side of dough in oats and place in baking pan, oat side up. Repeat to fill both baking pans with nine rolls each. Cover lightly with plastic wrap and let rise until almost doubled in size, 30 to 40 minutes. (Dough should barely spring back when poked with knuckle.) Bake until internal temperature registers 200°F on instant-read thermometer, 30 to 35 minutes. Remove rolls from pans and cool on wire rack before serving, about 2 hours.
