Oatmeal in a Slice

by David Lesniak, David Muniz from Baked in America

An inviting oatmeal slice recipe, which is ideal for breakfast or on the go. The goodness of oats in a bar, with the sweetness of cinnamon, nutmeg and raisins.

From the book

David Muniz, David Lesniak


This has all the goodness of a bowl of oatmeal only in a slightly different form. People can be quite specific when it comes to their morning oats, so by all means use this as a starting point if you’d prefer another combination. Sometimes we add nuts but we like it gushier so we leave them out. We’ve fiddled with this recipe quite a bit and our conclusion (for the moment, anyway) is that using both types of oats gives just enough structure and texture. It will come out just fine if all you have is one type. Old-fashioned or jumbo oats produce a nubbier loaf, while rolled or quick oats break down in the oven sooner so they are harder to detect in a finished slice. They produce a lovely, moist loaf without the telltale crunch of the larger oats.

2fl oz / 60ml / ¼ cup canola oil or the like
4fl oz / 120ml / ½ cup buttermilk
10oz / 275g / 1¼ cups applesauce, preferably unsweetened
2 large eggs
5½oz / 160g / 1 cup all-purpose or plain flour
1½oz / 40g / ¼ cup whole wheat or wholemeal flour
6oz / 175g / ¾ cup, packed light brown sugar
1½ tsp baking powder
1½ tsp bicarbonate of soda
½ tsp kosher salt
1 tsp cinnamon
¼ tsp nutmeg, freshly grated
2oz / 6og / ½ cup rolled or quick oats (not instant)
2oz / 60g / ½ cup jumbo or slow oats
3-4oz / 85-115g / ½ cup dark or golden raisins

Essential kit

You will need a 12 x 9in/30 x 23cm loaf pan.


Preheat the oven to 180°C/350°F/gas mark 4. Butter a 12 x 9in/30 x 23cm loaf pan, dust with flour and line the 2 long sides and bottom with parchment.

Put the oil, buttermilk, applesauce and eggs into a large measuring jug. By doing it in this order you can measure each successive ingredient into the same jug as opposed to using several. See, the primary chemistry lesson of displacement actually did come in handy! With a small hand whisk or fork, evenly blend everything together.

In a large mixing bowl, mix together the 2 flours, sugar, baking powder, bicarbonate of soda, salt and spices. Add the oats and fruit and toss together. Make a well in the dry ingredients and, all at once, pour in the wet ingredients. Stir until everything is evenly moistened, but be careful not to overdo it. Pour the batter into the prepared pan and even the top with a spatula. Sometimes we sprinkle demerara sugar on top of the batter.

Bake for 50 to 60 minutes, or until the bread is well browned and a thin knife emerges clean from the center. Let the loaf cool for about 15 minutes before removing it from the pan to cool completely on a wire rack. If you cut into the warm loaf, your slice may be a bit crumbly; it slices better when it has a chance to cool and set completely.
