Pumpkin Banana Bread

FullSizeRender 31.jpg

It’s September. School is back in session, it is no longer appropriate to wear white and Starbucks released the infamous PSL. Rather than a classic pumpkin recipe I thought I would experiment a little.

What do you get when you mix banana bread and pumpkin bread?

MAGIC!

On a hunch, I decided to intertwine the recipes for my favourite banana bread and pumpkin bread. With a few alterations, the creation came out perfectly. Not too heavy on the pumpkin, not too heavy on the banana – it is truly a delicious concoction. When serving it to someone, ask what flavour they think it is. About half have said pumpkin, the other half banana. Their minds are blown when you say both.

The banana bread base is an older recipe that has been altered over the years, however the pumpkin bread part comes from Gimmie Some Oven. Also a delicious fall dessert that I often make.

Ingredients:

2 cups granulated sugar
1/2 cup packed brown sugar
3 and 3/4 cup all-purpose flour
2 tsp baking soda
1 and 1/2 tsp salt
2 tsp pumpkin pie spice
1 cup pumpkin puree (pure pumpkin)
3 ripe bananas, mashed
2 eggs + 2 egg whites
3/4 cup melted coconut oil
1/4 cup greek yogurt (I used vanilla greek yogurt, but can also use plain or toffuti sour cream to be non dairy)
1/2 cup milk (can use almond milk to be non-dairy)
2 tsp vanilla extract

Directions:

1) Preheat oven to 350F.

2) Spray 9×13 pan with cooking spray, or line with parchment paper.

3) In a large bowl, mix together the first six ingredients (dry ingredients). Make sure to break up any large clumps.

This recipe is delicious for a crowd. It makes a 9×13 cake. Cut recipe in half to make a loaf cake and reduce the baking time by 10 minutes. It freezes well. Also works well with frosting (I’m partial to cream cheese frosting), but make frosting after defrosting the cake.

Science Fact of the Week:

Pumpkin is rich in vitamins and minerals. It is high in potassium, which may help lower blood pressure. It is also rich in beta-carotene and carotenoids, which, as antioxidants, may protect against cancer and cardiovascular disease. 

Earl Grey Vanilla Cupcakes with Vanilla “Buttercream”

FullSizeRender 27.jpg
Building on my last post, I’ve been on a little bit of a tea-kick. David’s Tea Cream of Earl Grey is one of my favourites, and incorporating it into some of my favourite recipes has been a unique challenge. I modified my vanilla cupcake recipe I’ve been using for nearly 10 years to add the strong earl grey flavour, giving these cupcakes a unique depth.

It took a few tries until this experiment was a success! After all, this is why we chose to call this blog The Science of Baking.

Ingredients:

For the Cupcakes:

1/2 cup earl grey concentrate (2-3 tbsp. earl grey tea and 1/2 cup boiling water)
1 3/4 cup cake flour
1 3/4 cup all purpose flour
1 3/4 cup sugar
2 1/2 tsp baking powder
1 tsp kosher salt
1 cup (2 sticks) nondairy margarine, room temperature, cut into 1/2 inch cubes
4 eggs
1 cup unsweetened vanilla almond milk
2 tsp pure vanilla extract

For the icing:

1 cup (2 sticks) nondairy margarine (softened)
1 tsp pure vanilla extract
4 cups confectioners’ sugar
2 tablespoons unsweetened vanilla almond milk

Directions

Preheat oven to 350° and line cupcake pan with cupcake liners.

1) Steep Earl Grey tea (in filter) with 1/2 cup boiling water. Allow to cool
2) Add the flours, sugar, baking powder and salt. Mix on medium speed until well combined (about a minute).

3) Add margarine, a few cubes at a time until mixture resembles coarse sand.
FullSizeRender 22.jpg
4) Add eggs one at a time
5) Slowly pour in almond milk, vanilla and earl grey concentrate. Beat for 2 minutes until smooth (works best with a mixer), scraping sides of bowl as needed.
6) Fill liners 2/3 full (about 1/4 cup batter) and bake for 15-20 minutes until tops are golden brown and centre is set.

Allow to cool completely before frosting.

7) Make the Frosting: Cream margarine. Add vanilla and gradually add sugar, scraping the sides of the bowl as necessary. Add almond milk and beat until fluffy. If desired, add food colouring.FullSizeRender 26.jpg
Makes 24 cupcakes. These freeze well unfrosted in a ziploc style bag. As well, the batter can be made in a 9 x 13 sheet pan (bake for 35-45 mins) or 9-inch circular pans (bake 25-35 mins) to make a cake.

Science Fact of the Week:

Similar to our friends the blueberries, Pure Vanilla Extract is rich in anti-oxidants such as vanillin. Using imitation vanilla decreases the anti-oxidant quantity, and therefore decreases potential health benefits. Vanilla has been shown to be anti-oxidant, anti-inflammatory,and anti-bacterial. As a result, it may reduce one’s risk of certain cancers. 

Earl Grey Scones with Vanilla Glaze

Now it’s my turn to give this a shot.
FullSizeRender 14.jpg

This summer I developed a bit of a scone addiction. It began when a colleague of mine suggested I try the scones at the coffee shop around the corner from work. Within a week I had tried nearly every flavour. Favourites included Wild Blueberry, Chocolate Espresso and Maple Oat. My colleagues even teased me because the scone would disappear before I even walked into the building door.

Naturally, as the curious person I am, I started looking up recipes. After trying a few others, I settled on The Blueberry Lemon Scone from Sally’s Baking Addiction. Based on some helpful suggestions from friends and a couple of my own ideas, I tweaked this recipe slightly, but I’ll save those hints for a future post.

Outside of The Science of Baking Laboratory, I’ve spent my summer working in an actual research facility. Once a week we have a team lab meeting, and I or my father has baked for every single meeting. I’ve used my lab as test subjects for each of my scone recipes (I don’t think they are complaining). The original blueberry lemon recipe inspired me to create different flavour combinations, and I now prepare a bowl of each flavour following the base of the initial recipe. Today’s post is a delicious Earl Grey Scone that pairs nicely with a cup of coffee.

As noted in the original recipe, working with frozen butter is what makes these scones what they are. I use a food processor to grate the butter, and a pastry cutter to incorporate it. If you don’t happen to have these tools, the butter can be grated by hand, and a fork is a great substitute for a pastry cutter. I also choose to weigh the ingredients to ensure precise amounts, but again, if you don’t have a scale, standard measuring tools will be sufficient. My scone addiction has prompted me to expand my university kitchen (I now own my own food processor – Thanks Mom!). Next up, an electric mixer!

Ingredients:

For the Scones:

2 + 2 tbsp. Earl Grey Tea (I use David’s Tea Cream of Earl Grey)
3 tbsp. boiling water
2 cups (240 g) all-purpose flour (plus extra for counters)
6 tbsp. (75g) granulated sugar
2 and 1/2 tsp. baking powder
1/2 tsp. salt
1/2 cup (115 g) unsalted butter, frozen (I throw it in the freezer ice drawer about 20 mins before I start making the scones, and take it out only when I’m ready to use it)
scant 1/2 cup heavy cream (I use 35% Cooking Cream)
1 tsp. pure vanilla extract
1 large egg

For the Glaze:

1 cup (120 g) confectioners’ sugar
2-3 tbsp. milk
1/2 tsp. pure vanilla extract (or 1/2 of a vanilla bean, seeded)

Directions:

Preheat the oven to 400˚F.

First, mix the boiling water with 2 Tbsp. of earl grey tea leaves. Alternatively, you can use two earl grey tea bags. Let it sit on the counter to cool down. This is the earl grey concentrate that gives the scones a strong earl grey flavour.

Next, take the other two tbsp. of tea leaves and grind them to a fine texture (I use a single-serve blender similar to the magic bullet). I grind them until they about the size of a sugar granule. If you are using tea bags, this isn’t necessary.

Mix the tea with the next 4 ingredients (flour, sugar, baking powder and salt) in a large bowl.

In a small bowl, whisk the scant 1/2 cup of heavy cream, vanilla, earl grey concentrate and egg.
FullSizeRender 7.jpgGrate the butter (by hand or in the food processor) and add to dry ingredients. Use a pastry cutter (or fork) to incorporate. (Please note: this picture is from the blueberry scone recipe – normally you would be able to see the small tea granules similar to the photo above)FullSizeRender 8.jpg Pour wet ingredients over the butter mixture and incorporate with a rubber spatula. Make sure not to over-work the dough.

To cut the scones:

  1. Cut vertically down the middle (creates two pieces)
  2. Cut each half in the middle vertically as well (creates four pieces)
  3. Cut horizontally down the middle (creates 8 pieces)
  4. Cut each of these pieces diagonally (creates a total of 16 scones)

Bake scones for 12-17 minutes. 15 minutes usually works perfectly for me.

If you want scones on demand, these freeze well (pre-cut) in an air-tight container. Ensure that scones are not touching each other (divide with parchment). They can be stored in freezer for a few weeks before baking. Add two minutes to baking time when baking from frozen.

I’ve now prepared extras to keep in the freezer, and just take a single scone out to bake in the toaster oven when I’m craving it. In the toaster oven I’ve found they need about 13 minutes from frozen (but I’m skeptical that we have an aggressive toaster oven).

Allow the scones to cool on wire rack.

Mix ingredients for glaze in separate bowl. Top cooled scones with glaze.

Science Fact of the Week:

Earl grey is a black tea synthesized from Camellia sinesis. Black tea contains polyphenolic compounds. These compounds have been associated with prevention of cancer and cardiovascular diseases (atherosclerosis and coronary heart disease). Although this isn’t the usual delivery vehicle for tea, you can easily pair these scones with a warm cup of earl grey tea to enhance the health benefits.
